Imagination?

Murray River.

Most of today was spent driving the 1,000km from Melbourne back to Copa.  I was on the road by 5:00am, after a night during which I woke several times.  I suspect the real reason for the disturbed sleep was that I knew I had an early start, but each time I woke, I found myself lying there, very conscious of my heartbeat and trying to determine whether the beat was regular.

After my 5km run yesterday morning, I was checking my pulse and it seemed that there was a double beat about every 20 to 30 seconds, although it could have been my imagination.  I hadn't experienced any breathlessness or palpitations while running, but nevertheless I'm now a bit worried that the double beat, if it's real, signals the early stages of the return of my Atrial Flutter.

Bike path along the Murray.

As I drove north along the Hume Highway in pre-dawn darkness, I wondered about the wisdom of running again today.  However, after three hours of driving and feeling a little tired, I stopped in Albury and set out along a bike path by the Murray River.  It was a pleasantly cool morning and I was pleased to feel more like a runner than earlier in the week, though somewhat apprehensive.  I wasn't running hard, but was moving faster with less stiffness in the muscles and joints.  The faster speed meant my lungs were working a little harder, and I was breathing in on two steps and out on one, but still controlled.  Nevertheless, I was constantly self-assessing myself, looking for any sign that my heart was racing or my blood pressure dropping.

Billabong at the turnaround.

After about 3km of following the full and fast-flowing river, I reached a billabong and the end of the bike path and turned round.  It was nice to see the Murray River looking so healthy after a number of dry years.

Hovell Tree Park.

The path returned through the Hovell Tree Park, where I had finished my 440km three-week hike along the Hume & Hovell Track about ten months ago.  The Hovell Tree was marked, nearly 190 years ago, by one of the explorers after whom the walking track was named.  I could vividly remember finishing there at dusk, completely exhausted after compressing the planned last two days walk into one 50km day.  Despite my exhaustion on that last day, I had a great trip, and being there again made me wish it was a year ago when I was preparing for the trip, with no heart or lung problems in sight.  Just another reminder to make the most of my time.

I was again checking my pulse again after the run, and still wonder if there's an occasional double beat.  Generally, it seems regular and strong (and back under 50bpm at rest), but I still have a nagging concern.  I have an appointment with the cardiologist next week anyway, and he'll confirm one way or the other.  For the time being, I think I keep running daily.

Warfarin?

My usual 5km while staying in Melbourne passes along
some of the leafy Malvern streets.

After six days of running about 5km a day, following two months of no running, I'm about where I expected to be in terms of cardio-vascular fitness.  My diagnosis of Deep Vein Thombosis, Pulmonary Embolism and Atrial Flutter at the start of January, had me worrying whether I would ever run again.  It was a scary time.  Now that my heart is back in sinus rhythm and I'm taking Warfarin to minimise the risk of further blood clots, running is again part of my life.

I have resumed running after injuries many times in 45 years, and generally know what to expect.  There will be two weeks, or longer if I have added a few kilograms, of feeling like a fish out of water.  After that, I will begin to feel like a runner again.  Then, the return to full fitness is generally a function of how long I had been unable to run.

The run passes by the John Landy Oval
(see post here).  

I'm mid-way through the initial couple of weeks and there's no problem with my cardio-vascular system.  I'm breathing easily and my heart rate seems to be behaving itself.  What is bothering me, is how stiff and sore my legs are.  Every morning, I feel like all my joints and muscles need lubrication as I set off.  I'm surprised I don't hear squeaking!  It's worse than I expected, and I have been tempted to blame it on the Warfarin I am taking.  If my blood is slow to coagulate, maybe the inflammation that must be occurring in my ageing and cartilage-poor joints is slower to repair and then dissipate?  Maybe there is some other side-effect?

Looking across John Landy Oval in Malvern's
Central Park.

I have searched high and low on the internet for information about the effects of Warfarin on runners, but instead of finding clues to explain my aches and pains, I have found stories of endurance athletes successfully returning to serious competition while continuing to take Warfarin.  Seems like I will have to accept the ageing process is the main culprit.

Just another 5km this morning at an easy pace, with no problems apart from the above-mentioned stiffness and soreness.

Walking and pondering

The backlots of McMasters Beach on this morning's walk.

I walked about 10km this morning in misty, drizzly, and almost autumnal weather along some less-travelled roads and trails around nearby McMasters Beach.  Walking gives more time to look at your surroundings, and I've enjoyed a closer examination of the forests and properties that I often pass more cursorily on the run.  It's all relative, of course, with walking better than running, and running better than biking, if you want to absorb your environment.  All are better than driving.

The gravestone of Allan McMaster, the first European
settler in the area named after him.

Another advantage of walking, for me at least, is that it is the best time for thinking.  I'm a stroller rather than a power walker, and the gentle perambulation seems to stimulate my analytical brain cells.  As I walked this morning, experiencing no breathlessness or heart palpitations, I wondered about the chances that my heart problems were behind me.  If not, how would the return of the Atrial Flutter (AFl) be triggered?  By running too hard?  And if it was triggered, would it suddenly be as debilitating as it was before the Cardioversion, or would the onset be slower?  What were the chances of reversion, and what were the risk factors?  Wouldn't the cells through which my heart was passing the errant electrical pulses still be there, just a dormant pathway waiting to be reactivated by stress or some other trigger?

Umbrellas were optional on a drizzly morning walk.

There was lots to think about, inconclusively, and I returned home to do some more Googling.  Nothing I could find gave me more certainty, but there were clues.  One study in particular, of men a similar age to me, found that 55% had recurrent AFl within six months of their Cardioversions.  Underlying heart disease, previous episodes of AFl, and enlarged left atriums all seemed to be statistically significant factors in those who reverted.  I'm not conscious of previous AFl events, and my cardiologist found no evidence of heart disease, but he did find "mild Left Atrial dilatation".

Cockrone Lagoon on an autumnal morning.

Other studies have found enlarged left atrial size to be more common in long-term endurance athletes, than others of a similar demographic, and that this seemed to be associated with great incidence of Atrial Fibrillation (AF) and AFl.  So, it seems reasonable to assume I remain at significant risk of reversion.  The great unknown for me, though, is whether the enlarged left atrium was the key factor in the development of my AFl, or was it the Pulmonary Embolism (PE) placing undue pressure on the heart's function that was the trigger.  Although I'm probably stuck with the enlarged left atrium, the PE should be gone soon, if not already.  Does that mean there's a good chance I won't have the problem again?  Probably not, but only time will tell, although there will never be a point at which I can say there is no further risk.

1:1 AV Conduction

One of my heart rate peaks, as measured by the
Holter Monitor.

Late today, I had my Cardiologist appointment to discuss my recent Echocardiogram and Holter Monitor results.  He was a fit-looking guy in his fifties and was sympathetic to my plight and my desire to resume running.

It seems that my efforts to give them something to look at while I was wearing the Holter Monitor a week ago were more successful, and risky, than I thought.  The two episodes I had of palpitating heart and lightheadedness while walking up a steep hill, matched recorded instances of my heart rate reaching around 230 beats per minute.

Diagram of the heart showing the path of the macro-reentry
circuit (wavy red line).

Normally, the upper (Atrium) and lower (Ventricle) chambers of the heart beat at the same rate.  However, with Atrial Flutter (AFl), the Atrium beats significantly faster than usual because of a sort of electrical short-circuit (macro-reentry circuit) and a proportion of these faster beats stimulate beats in the Ventricle.  The rate of conduction is determined by a physiological barrier between the chambers and is usually 2:1 for people with AFl (and sometimes 3:1 or 4:1).  When I walk too hard, or run, my ratio appears to change to 1:1 where every superfast beat in the Atrium stimulates a corresponding beat in the Ventricle.

One medical website I found says "Atrial flutter with 1:1 conduction is associated with severe haemodynamic instability and progression to ventricular fibrillation", so I need to keep my heart rate lower until I get treatment.  This diagnosis was a little more worrisome than I had anticipated.

The cardiologist is scheduling me for an Electrocardioversion within the next week aimed at resetting my heart's electrical system (in layman's terms) using externally-delivered electrical stimulus (the paddles, or similar).  The cardiologist warned that this procedure may not yield a long-lasting solution, so I shouldn't get my hopes up.  I will be able to resume my running, but the AFl could return, and I will have to stop again.

If that happens, then when I'm no longer considered at risk of further Deep Vein Thrombosis or Pulmonary Embolism, they will try a Cardiac Ablation using a catheter inserted into the heart through the femoral vein to cauterise the tissue where electrical short-circuit is occurring in the Atrium.  This procedure has a high success rate and provides a longer-lasting solution, but I know everybody is different and I'm not counting my chickens yet.

I walked about 5km today, with no significant hills, and felt fine.

Psychological effects

5:30am in Terrigal and the first Trotters begin checking
for the Saturday run or walk.

Like most Saturdays, today started with a 4:30am alarm and arrival at the Terrigal Surf Club fifty minutes later to join my Trotters club-mates for our weekly 6:00am run.  Only, I'm not running at the moment......but I'm not alone.

I have never analysed the stats, but my guess is that you could divide the Trotters population into quarters.  One quarter are fit and running well. Another quarter are running, but carrying an injury.  A third quarter are running, but coming back from injury, and the final quarter are unable to run because of illness or injury, some permanently.

Kurrawyba Avenue in Terrigal was on
my walk route this morning.

Many in that final quarter are not only dealing with pain associated with their ailment, but also dealing with the psychological impact.  Fortunately for me, there's no physical pain, but I do feel the psychological effects.

The easiest to deal with is the loss of routine.  Like most serious runners I have always relied on routine to help me fit training in with family and other commitments, and the loss of routine can be destabilising and depressing.  Replacing running with some other form of exercise, if at all possible, and using any additional spare time to work on other useful or meaningful projects has generally worked for me.

One of the most challenging impacts can be the loss of identity.  The thing that most people know about me is that I'm a reasonably good runner.  Although I like to think there are other dimensions to my character, I do also see myself as a runner.  In the last month, in my own eyes, and the eyes of those around me, I am morphing from a serious masters athlete to a senior citizen with cardiovascular problems.

Sunrise over Terrigal.

Along with the loss of identity can go a loss of self-esteem.  The podium finishes that I enjoyed in the past, and these days, just keeping up with younger runners, builds self-confidence.  Absorbing challenging training regimes and successfully planning and preparing for major races also contributes positively to self-esteem.  The longer I am unable to run, the less happy I am with myself, even when there's nothing I can do about it.  And the worse I feel about myself, the more likely I am to over-eat and put on weight and so the downward spiral goes.

I also have real fears that being unable to run for an extended period of time will lead to a deterioration in my overall health.  Of course, it seems likely that running caused my current cardio-vascular problems, and I recognise that running is not a guarantee of good health.  However, I have no doubt that the fitness gained through running has improved my quality of life and fended off other ailments that beset my demographic.  I now worry that all that good work will be undone if I can't get back to serious exercise.

Early morning stand-up paddle boarders.

Finally, I have always found that running refreshes me and helps me deal with life's stresses.  This was certainly true during my working life, where the morning run seemed reset my body clock and wipe away (or at least diminish) problems.  Maybe it's the lack of oxygen getting to the brain, but I always found it difficult to worry about things, or even do relatively simple mathematical calculations, while on the run.

While most of my club-mates ran this morning, I walked a comfotable 6km.  I'm still in a holding pattern.

Perspicacious medicos

Cockrone Lagoon, between McMasters Beach and Copa,
and near our home, is one of my favourite places to walk.

I walked 5km this morning, and although not as bad as yesterday, still felt more breathless than has generally been the case in the last few weeks.  Maybe I've just had a bad couple of days.  I have read stories on the Web of runners coming back from Pulmonary Embolism (PE) who have bad patches.  Nevertheless, I was pleased I had an appointment scheduled for later in the morning with a Respiratory Specialist to get an expert opinion on my situation and some answers to questions.

Cockrone Lagoon.

As it turned out, the Specialist's opinion was that the worst of my Deep Vein Thrombosis (DVT) and PE was past, and that as long as I was taking the anti-coagulant, Warfarin, my prognosis was good.  In fact, if my heart wasn't an issue, he would have been OK for me to resume running, which was good news.  He spent some time checking my pulse, and said he was sure that the breathlessness I had been feeling was due to my heart which was beating irregularly, averaging about 60-70 beats per minute compared to my usual resting rate of low 40s.

Cockrone Lagoon.

He seemed keen that I see the Cardiologist (my appointment is four weeks away) as soon as possible and actually tried to get me an appointment today (they are in the same building).  I think the urgency was driven by his desire to help get me running again rather than any concern about my current condition, although he didn't actually say that.  He told me he was training for a triathlon, confirming to me the wisdom of getting a Specialist recommendation from my sports medicine friend, Dr Jon.  In my experience, medicos who participate in endurance sports have a much better understanding of obsessional distance runners such as myself.  They know how much it means if we cannot run, how much we test our physical limits, and how prone we are to ignore pain.

He prescribed another heart test, a Holter Monitor, and told me to call the Cardiologist when the results were available, mention his name, and I should be able to get an earlier appointment.  I called to arrange the test, and because they had a cancellation, was able to get an appointment this afternoon.  I'm now walking around with electrodes attached to various parts of my chest and connected to a battery powered recorder on a waist belt.  I have to note the time of any breathing or heart events I notice in the next 24 hours and return the device tomorrow afternoon.  Hopefully, I'll be able to get an appointment with the Cardiologist next week and make progress on the heart problem.  I sensed the Specialist I saw today thinks the heart arrhythmia will be correctable, but time will tell.

London

St Paul's Cathedral.

In total, I have lived ten years of my life in the UK and am very fond of the place.  In various blog posts (Frost Fairways,  Chappel, Isle of Dogs), I have described some of my favourite runs there.  The last time I lived in the UK was in 1992, but during the next eleven years when I lived in the US, I made many business trips there, frequently staying in hotels in central London.  Central London is a big place, and depending on where you are staying, the running options can vary.  During the latter part of my working life, when I was employed by Reuters, whose head office was in Fleet Street, my favourite place to stay was a business hotel close to St Paul's Cathedral.  It was easy walking distance from the office (passing an excellent Indian takeaway en route!), and close to the Thames River, a wonderful place to run.

HMS Belfast with Tower Bridge.

For my regular 10km run, I usually set out about 6:00am and headed east along Cannon Street past the imposing St Paul's Cathedral and then Mansion House, Cannon Street and Monument stations which were already disgorging early commuters before arcing around the northern side of the Tower of London and onto the iconic Tower Bridge.  I always enjoyed checking out the river traffic as I crossed the bridge and looking at the retired HMS Belfast anchored upstream.  On the southern side of the bridge, I descended a stairway to begin my journey westwards along the southern bank of the Thames.

Millennium Bridge and St Paul's Cathedral.

At first the route wound through some narrow back streets passing refurbished warehouses and stereotypical London pubs before joining the promenade along the river bank which I followed all the way to Westminster Bridge.  On the way it passed landmarks such as the Millennium Bridge, the Tate Modern, Southbank, and the London Eye, all the time providing superb views of the London skyline to the north across the river.  After crossing the river again beneath Big Ben, the route turned right to follow the Victoria Embankment downstream and back to the northern end of the Millennium Bridge from where it was a short run back to the hotel.

London Eye and Southbank.

It was a generally flat course along wide paved footpaths and promenades that made for a fast run if I was feeling good, which was often the case.  In summer, London had milder temperatures and lower humidity than my US abodes, and in winter, it was also milder and nice to run in shorts for a change after the winter gear required in the US.

I've been told that my recovery from the Pulmonary Embolism could be long and erratic.  Today served to emphasise the point when I struggled all of the way round what should have been an easy 5km walk in Copa.  I didn't feel my heart racing, maybe because I walked so slowly, but it was exasperating and a little alarming to feel so unfit.  My breathing was heavy and laboured and I even contemplated sitting down on a bench with a kilometre to go when I began to feel a little spaced out.  Instead, I just walked even more slowly and made it home OK.  The rest of the day was pretty sedentary and I had no problems.  On the plus side, I had a call from the office of the Respiratory Specialist I wasn't scheduled to see for another month to say they had a cancellation tomorrow, so I'm hopeful of getting a useful opinion about my situation and prognosis.

“On Death and Dying”

Looking towards Avoca Beach from North Avoca
during today's walk.

Serious runners with more than a few years behind them will be familiar with the psychological impact of injuries.  As discussed in my post titled "Punctuated Equilibrium", major injuries have derailed my running and racing plans and, perhaps, permanently inhibited my running potential.  Even soft-tissue injuries that later healed completely, were devastating when they thwarted plans for a big race. In dealing with such injuries, to some degree or another, I have recognized my own emotional progression in the stages identified by Elizabeth Kubler-Ross in her seminal work “On Death and Dying” - Denial, Anger, Bargaining, Depression, Acceptance.

With my recently-diagnosed health problems - Deep Vein Thrombosis (DVT), and associated Pulmonary Embolism and Atrial Flutter - I can feel myself travelling the same road again.  The territory is familiar, though maybe amplified by the potential whole-of-life impact of the diagnosis, and I am confident I will eventually reach the "Acceptance" stage.  In the meantime, I'm tracking my progress through the earlier stages of the process.

Avoca Lagoon.

Denial.  When, during the Terrigal Trotters' Santa Run just before Christmas, I first experienced unusual shortness of breath, palpitating heart and excessive fatigue, I didn't believe there was a serious problem.  It was warm and humid, I had been training hard, and I was wearing an Elf suit.  Worst case, I had picked up some kind of bug, which would pass in a few days.  I was still in denial a week later, but finally accepted something was seriously wrong when I struggled badly a week later in the monthly Trotter's 10km Time Trial.

North Avoca Lake Track.

Anger.  After the diagnoses, it appeared likely the originating DVT resulted from failing to drink enough following a warm long run before having a longish nap.  Low blood pressure, viscous blood, and inactivity combined to produce clots.  No doubt other risk factors were involved, but addressing these two may have prevented the problem.  I kept returning to the day in question and asking myself why I didn't stop at a store on the way home to buy a drink, as I would usually do, and why I recently started having post-run naps when for decades I had "pooh-poohed" the idea?  Why had the heart and lungs that had served me faithfully for 45 years of serious running now let me down?  Shouldn't the years of training have made them more resilient?  Would things have been different if I hadn't recently changed my shoe brand after decades with Nike Pegasus?  Overnight I had moved into a new demographic.  I was now discussing heart issues with my step-mother as an equal when a month earlier we had seemed to live on different health planets.  There was also anger that I could no longer exercise with the same intensity, perhaps impacting my health in other respects.

Avoca Lagoon.

Bargaining.  I have kept Googling, reviewing the medical websites and the experiences of others, and theorising on the quickest acceptable way to return to running.  Positive snippets of information are seized on, but often discounted or disregarded after rational consideration.  If I have larger lung and heart capacity than the average human, then even if they are functioning sub-optimally, I should be able to jog conservatively when others would be limited to a walk?

I'm still in the "Bargaining" phase because I don't have good information about my prognosis yet.  No doubt, I'll keep coming up with hypotheses that get me back to running sooner rather than later, but know that expert opinion based on my particular situation is needed, and that feedback will only start with my specialist appointments at the end of February.  I periodically experience some symptoms of the "Depression" and "Acceptance" phases, but feel those phases are yet to come, and I will discuss them in a future post.

Another 10km of easy walking for exercise today following the early morning track session at Terrigal Haven.  I tried walking somewhere less familiar to make it more interesting and that seemed to work.  If I want to keep walking 10km each day, maybe I'll have to drive to some varying locations.

Punctuated equilibrium

Hanging upside down was one of
the treatments I tried for my chronic
back injury.

When I was in my running prime, I gave little thought to athletic decline.  I knew many veteran (masters) runners and recognised my potential as a runner would decline as I aged.  However, I never thought much about the process.  If anything, I expected the decline to be a smooth glide path.  Each year would see slightly slower times for benchmark distances and I would be chasing podium places as I entered each new age group.  It was a naive and simplistic view of the process, and my only defence is that these issues seemed remote and I didn't give them sufficient thought.

Now, with ageing parents and my own ageing body, it has become obvious the process of ageing and athletic decline is more akin to the evolutionary biology theory of "punctuated equilibrium".  This postulates that, over time, long periods of stability with little change are punctuated by events causing significant change.  Rather than being on a gradual descent to our ultimate demise, or the end of our running career, we have periods, often lasting years, when our abilities and capabilities remain relatively static.  As runners, these stable periods may include various soft tissue injuries and oscillating fitness, but our basic capabilities are essentially unchanged.

Looking towards North Avoca from Avoca Beach
during this morning's walk.

Significant events for runners are those injuries from which we never really fully recover, despite how hard we train.  There were no more Personal Bests for me after a back injury (spondylolisthesis) sustained  in 1979 brought to an end the steady improvements I had seen in the preceding years.  Likewise, a serious knee injury in 2006 meant a lot of time off running and a limit on training load I could sustain in subsequent years.  I could plot other significant injuries over the years that have also had a lasting impact on my running capability.

Looking from Copa, low cloud covers Mount Bouddi
during this morning's walk.

Now I'm trying to reconcile myself to the capability change that will result from my Deep Vein Thrombosis and associated Pulmonary Embolism and Atrial Flutter.  I'm still in the midst of this "event" and don't know the level of capability I will emerge with, but it will almost certainly be less.  Goals will have to be recalibrated, or frustration will build.  I'm not reconciled to these changes yet, but can sense I am in the midst of the process and will eventually accept what must be.

This morning, I walked a comfortable 10km in misty rain beneath low cloud.  It was a nice change from the relentless summer weather of the last three weeks.

When to run again?

My walking route this morning took me through the
Avoca Beach Markets.

When I went to bed last night I had decided that today's exercise would include some light jogging.  It's not so much that I'm desperate for an endorphin high, or even the satisfying fatigue that follows a run.  It's more that I was very fit four weeks ago and I can feel that condition ebbing.  I know these feelings are familiar to all injured runners, but this time around I'm conscious that a miscalculation on when to start running again could feasibly have fatal consequences rather than just a setback in recovery time.

Avoca Beach Markets.

So, this morning, while enjoying my cup of decaffeinated coffee, I surfed the Web and pondered the most rational approach to a return to running.  I don't want to take stupid risks, but I don't want to be too timid either.  Finally, I decided to just walk 10km today and use the time to work out a rational strategy.  I do my best thinking while walking.

The first conclusion I reached was that the Deep Vein Thrombosis (DVT) diagnosed seventeen days ago was still at significant risk of throwing off small clots that could impact my lungs and heart.  Many sites on the Web indicated a minimum of four weeks and usually six weeks for DVT's to resolve themselves.  I should probably wait another three weeks and possibly an "all clear" from another ultrasound exam of the lower right leg before resuming jogging.

Avoca Beach Markets.

The second conclusion I reached was that my exercise, whether walking or running (when the time comes), should be at a pace which does not push my heart/lungs into what I'm calling the "Amber Zone".  Twice during today's 10km walk, near the top of steep and longish hills, I could feel myself beginning to struggle for breath and an unpleasant sort of pressure (not pain) building in the base of my chest as my heart began to race.  It was as though the clutch was slipping and no drive was being transferred from the engine to the wheels.  This was the same feeling I had when running faster up hills just before being diagnosed with Pulmonary Embolism (PE), so I'm becoming familiar with it.  I didn't have to stop walking for the sensation to abate today, but did need to slow right down to a dawdle.  I would define the "Red Zone" as being the need to stop and sit down, and I have not reached that point yet, nor do I want to.

Avoca Beach Markets.

Like most chronic injuries, I feel like I'm starting to get a handle on how to manage it, but know it is not wise to look for the "edge of the envelope" as has been my inclination in the past.  I also know that, even after the DVT has resolved itself and the clots in the lungs are no longer an issue (which could take months), I will still likely need some sort of medical procedure to address the Atrial Flutter problem before I can start running hard again.  Patience!

[I have posted my Post-DVT Training Diary here, or it is accessible from the Links menu at right.]

Fibrillation or flutter

Part of my walk around Copa today

I wasn't really anticipating any good news when I had a long consultation with my GP today, just a summary of the tests so far and referrals to some specialists.  If anything, I came away a little more positive.  She confirmed that all of the blood tests for more sinister underlying conditions had come back within normal range, and provided more detail on the cardiac tests and leg ultrasounds.

Apparently, the cardiologist diagnosed Atrial Flutter (AFl) rather than Atrial Fibrillation (A-fib) as being my heart condition, and according to the GP, this is the better diagnosis to have.  I gather A-fib is chaotic disorganised beating of the Atria while AFl is regular, but way too fast, beating of the Atria and may be a little easier to treat and sometimes stops of its own accord.

Looking north from Captain Cook Lookout
during today's walk

The leg ultrasound report found "some occlusive thrombus in one of the peroneal veins from 7cm below the knee crease to 20cm below".  The GP says her starting theory would be that the thrombosis in the leg has thrown off small clots that have impacted both my lungs (Pulmonary Embolism) and heart (AFl), but has referred me to a respiratory specialist and a cardiologist to try and confirm the diagnosis and prescribe treatment.  In the meantime, I continue with the Warfarin anti-coagulant.  The earliest specialist appointments are six weeks away, but I guess the fact that I'm not seen as an urgent case is a good sign.  It probably means, however, that my exercise is going to be limited to walking until at least the end of February and any prospect of returning to serious marathon training in time for the Gold Coast Marathon in July is remote.

Looking south from Captain Cook Lookout during
today's walk

I won't abandon the marathon goal until I speak with the specialists, and dearly want to resume regular running.  However, I am already mentally more focussed on the need to be fit for my next planned adventure, a 3500km southbound hike along the Appalachian Trail from Maine to Georgia in the eastern US starting in Autumn (October) and finishing in the Spring (March).  I know there is a possibility that this too could be scuppered by my current health problems, but I'm trying to be optimistic.

I walked about 8km today, not particularly quickly, and felt fine the whole way.  I gather that regular leg use is recommended in the treatment of Deep Vein Thrombosis, so being able to walk 8km without pain or other problems must be a good thing, I reckon.

Little (Beach) hiccups

Looking towards McMasters Beach

For today's blog post, I was planning to write about one of my favourite local 10km runs, the Little Beach circuit, and set off to walk it with my camera.  This was to be my longest walk since I stopped running two weeks ago, but I reckoned that provided I didn't push it I would be OK.  Going clockwise, the first section of this course goes along the beach to the village of McMasters Beach.  It was a beautiful sunny Sunday morning and the beach was busy with holidaymakers walking and jogging its length.  The fairly steeply sloping beach meant walking up on the softer sand to avoid getting my shoes wet by the occasionally larger incoming wave and I could feel I was working harder than if I had been walking along a road.

McMasters Beach

I didn't slack off, keeping up a good pace and left the beach at McMasters to climb a steep concrete path that would take me towards Bouddi National Park.  I walked quickly up the short hill, but near the top began taking huge gulps of air and could feel my chest pounding, as it had done on a few runs in the week before being diagnosed with Pulmonary Embolism (PE).  Not good!  Only a month ago, I would have run up this hill without even noticing it.  I slowed to strolling pace and decided to cut my walk short and head home.  On more gradual gradients at an unpressured pace, I was fine and got home without further concern, but the whole episode was quite depressing.  Not knowing whether the problem is the PE or Atrial Fibrillation (AF) or both, and what can be done about it, just compounds the problem.

I know I just have to be patient, and although I'm determined to keep walking up to 10km a day, this morning's episode reinforced the need to avoid pushing the pace.  According to my Web research, there's no standard time for blood clots to dissolve, whether in the legs or lungs and I must resign myself to several more months of limited exercise, at least.

Cockrone Lagoon at the end of today's walk

Today was also the day on which the 64km Bogong to Hotham race was held in the Victorian Alps, an event I had been training for before the PE hit.  Several times during the day, I thought enviously about where the runners would be on the course, and that hasn't helped my mood.  I have a consultation scheduled with my GP tomorrow, and although not expecting any new revelations, I do anticipate getting referrals to specialists where I'm hoping for more clarity about my condition and prognosis.  However, it won't be a speedy process.

More theories

I unexpectedly struggled midway through a long trail run
near the Barrington Tops four months ago.

The longer it takes to see specialists about my Pulmonary Embolism (PE) and Atrial Fibrillation (AF), the more time I spend on researching the conditions on the Web, talking to other people, retrospective self-analysis and theorising about my prognosis.

I was quite depressed following the surprise (to me) AF diagnosis, but after researching athlete experiences for yesterday's blog post (see Endurance athletes and A-fib), I'm starting to feel cautiously optimistic that I will be able to resume running.  Maybe I have had Paroxysmal (occasional) AF for some time, triggered by exercise fatigue.  Many people have AF and are unaware of it.  Maybe AF explains the unexpected and sudden onset of severe fatigue during some long runs in the past six months, including the Melbourne Marathon (see blog post Reality check).  I had put them down to lower back issues affecting my stride, for want of a better explanation.  When AF occurs, the heart beats inefficiently and less oxygen reaches the muscles causing fatigue.  The long runs when I had trouble were all at a time when I was building from a lay-off and possibly going a bit too hard for my level of fitness.  Later long runs, when I was fitter, but running within myself, were faster without trouble.

Struggling in the Barrington Tops

This is all amateur conjecture, and perhaps there will never be certainty, but it does make me think, that once the PE and Deep Vein Thrombosis conditions are resolved through time and Warfarin, I will be able to make a return to running, much more aware of my situation and more able to manage it.

It was a beautiful summer morning for the regular Terrigal Trotters Saturday run.  I was there early to take care of runner registration as Kev, the Club Registrar was away in Parkes for the Elvis Festival, and enjoyed greeting the 100+ runners who turned out.  Many kindly asked after my health and I later had the benefit of talking to a couple of club-mates who recently had surgery for similar heart issues.  My regret at not being able to join everybody for the 11km "Round Drive" run was somewhat tempered by a pleasant 6km walk with some great coastal views and the usual post-run bonhomie.

Perseverance is not always good

Deep Vein Thrombosis is the formation
 of a blood clot (thrombus) in a deep
 vein, predominantly in the legs.

There are whole worlds out there that I know little or nothing about.  I'm a bit of a current affairs nut, and an avid reader on a wide range of subjects, but there's nothing like a new injury or illness as motivation to expand your knowledge of a subject.

During my running life I have had serious injuries to my Achilles tendons, knees and lower back, as well as the usual torn and strained muscles, tendons and ligaments.  In each case, I've learned a lot about those injuries, including through missteps I have made in dealing with them.

I like to think that my own experiences allow me to offer soundly-based views on the running-linked injuries of friends when asked.  In the case of soft tissue injuries, I generally advise patience and the avoidance of activities that worsen the symptoms.  If something seems more serious or inexplicable, I usually suggest starting with a doctor.  They have a range of diagnostic tools at their disposal and a broader range of knowledge about the possible causes than ancillary or alternative health care professionals.  I'm not a fan of starting with the latter because I believe their field of knowledge and the tools they have available make it less likely they will consider all of the possible sources of a problem.  This can lead to misdiagnosis and a delay in recovery.

Pulmonary Embolism  is a blockage of the main artery
of the lung or one of its branches by a substance
 that has travelled from elsewhere in the body
through the bloodstream (embolism).

In the last two weeks, through doctors, the Web, and articles given to me by others, I've become a lot wiser about the subjects of Deep Vein Thrombosis (DVT), Pulmonary Embolism (PE) and Atrial Fibrillation (AFib), and their associated symptoms, treatments and prognoses.  Of course, there's much more I don't know about these subjects, but one thing I have learned is that runners need to be much quicker in seeking the opinion of a doctor if they start to feel inexplicably short of breath, dizzy or light-headed, or experience chest pains, hyperventilation or persistent leg pain.  There can be life-threatening medical conditions underlying these symptoms and endurance runners are at higher risk of developing them, especially if they have a long background of endurance training.

Atrial Fibrillation is the most common cardiac arrhythmia
(heart rhythm disorder).  The normal regular electrical impulses
generated by the sinoatrial node are overwhelmed by
disorganized electrical impulses usually originating in the
roots of the pulmonary veins, leading to irregular conduction
of ventricles impulses which generate the heartbeat.

Many runners, and particularly males, think seeking medical advice about these symptoms is a waste of time and/or a sign of weakness.  All endurance athletes get used to dealing with fatigue and injury "niggles" and there's a strong temptation to dismiss them as a "cost of doing business".  Two friends, both distance runners, have recently been diagnosed with PE, but only after persevering with their symptoms for much longer than me and ending up in hospital emergency wards.

I will now be quick to advise any runners suffering from the symptoms described above to urgently seek the advice of a doctor.  Early intervention is important and delay could be fatal.  It's just not worth the risk of persevering.

After mentoring this morning's track session at the Terrigal Haven, I walked for about 6km, feeling fresh and healthy the whole way, and wishing I could be running my usual post-track session 11km.

Trotters

Terrigal

Last night was the monthly Terrigal Trotters Committee Meeting at the Terrigal Surf Life Saving Club.  I always get a sense of privilege rocking up to the Surf Club on a Monday evening during holiday season.  Terrigal is a very popular holiday destination and during the summer you have to make your way through throngs of holiday makers knowing that by next month's meeting they will all be back at work or school and you will still be here, continuing to enjoy the delightful beach, hinterland and weather that have attracted them for their vacation.

Terrigal Surf Life Saving Club

Over my athletic career, I have belonged to a succession of running clubs - Melbourne High School Old Boys (defunct), Kew Camberwell District (defunct), Croydon Harriers (UK), Colchester & Tendring (UK), Watford Harriers (UK), St Louis Track (US) - and now Terrigal Trotters.  Along the way I have served in various Committee positions in some of these clubs and Terrigal Trotters stands out as unique.  Most Clubs seem to rely on two or three people to do much of the work assisted occasionally by other club members.  At Terrigal Trotters, without counting the numbers, I would guess that there are 20 people who make a very significant contribution to the Club's activities and many more who are willing to help out with particular events.

Terrigal Trotters Santa Run

The Committee is energetic and the Club inclusive.  Membership is growing and there are new people showing up for every Saturday's run, many of whom soon become hooked on the format and camaraderie.  It's fun to be a part of and volunteers enjoy involvement in professional and successful events.  Such success feeds on itself, drawing in more volunteers and participants.

Each month, one of the Committee Meeting agenda items is to nominate people who have made an exceptional contribution to the Club in the previous month and then select a Club Person of the month.  It is illustrative that there were 30 members nominated for their efforts in the past month.  Surely a sign of a vibrant club doing it's bit to promote fitness, health and fun.

Terrigal Trotters Christmas Party

My exercise today was another 5km walk around Copa.  I felt good and really wanted to be running.  Unfortunately, resumption still seems to be some way off.  My Echocardiogram this morning revealed significant Atrial Fibrillation in my heart and the specialist immediately sent me off for an Electrocardiogram (ECG) which confirmed his diagnosis.  The results still have to be reviewed by a Cardiologist, so I don't have a detailed report, but Googling the condition makes it plain that I have been lucky, will remain on Warfarin to reduce the risk of Stroke, and will need to consult some specialists before daring to run again.
