Back on track?

My UK visitor, Liam, the son of my long-time
running buddy, Keith, nears the top of the
challenging Hastings Road hill this morning

I've missed a couple of days of blogging while I had some guests staying.  On Monday, I just did some walking as intended and was pleased that my troublesome heel didn't seem to have deteriorated as a result of Sunday's long run.  I did, however, have some tightness in the lower hamstrings, the same places as cramp threatened many times on Sunday.

I warmed up for over 3km on Tuesday before joining the usual group of Trotters for a 10km run incorporating a few large hills.  The warm-up did the trick and I felt surprisingly good during the run.  My thinking is that, although the Sunday run was thoroughly exhausting, the exhaustion was primarily caused by dehydration.  The dehydration compelled me to run more slowly than would otherwise have been the case, and consequently my body wasn't as trashed as it might have been.  Once my fluid levels were back to normal I was not as tired and sore as feared.

I ran 14km this morning, still somewhat bothered by the hamstring tightness and pain in the right heel, but feel that both issues are improving.

My entry for the Bogong to Hotham 64km trail race in early January has been accepted and becomes my target race in this training cycle.  As part of my planned preparation, I would really like to run in the Deep Space Mountain Marathon, near Canberra, this coming Sunday.  However, I'm reluctant to race if I have any lingering heel or hamstring soreness because I know I will be going all out and risk more serious injury.  Fortunately, it's a low-key event that I can enter at the last minute, so really don't have to commit yet.  My rational self says that over the next four days both injuries will improve sufficiently to let me run.

Fatty acid catalyst?

The usual source of caffeine.

I'm successfully sticking to the caffeine limit I imposed on myself of 200mg or less a day (see blog post titled "Caffeine") after being diagnosed with an Atrial Flutter at the beginning of the year.  I do miss the "feel good" surge I used to get from that strong mug of coffee on days with an early start, but I don't miss the feeling that my blood pressure and heart rate were up.  Generally, I feel healthier without that caffeine and don't think I'll ever go back.

At the time of the blog post about caffeine, I mentioned that it is a legal stimulant that may have benefits for long-distance runners.  Apart from the value of heightened alertness and positive mood, there is evidence it plays a role in energy derivation.  I don't know when the research was first published, but sometime in the 1970s I read about the value of caffeine in releasing fatty acids into the blood stream.  In simplistic terms, as I understand it, during any long distance race, the body primarily derives its fuel from its glycogen stores.  This is the most efficient source of energy but supplies are finite and likely to be exhausted before the end of a marathon.  When the glycogen stores are gone, the body begins to burn fats, a much slower process.

The fatty acids stimulated by caffeine ingestion have been shown to bring fats into the energy fuel process earlier than otherwise, so that a marathon runner's stores of the more efficient glycogen will last longer, perhaps to fuel a late surge in the race.  I read somewhere that two strong cups of coffee about an hour before running was the best timing and dosage and I did try that a number of times during my marathon running heyday.  Of course you never know whether it makes any difference, and the risk is that when you can't do it for some reason (perhaps large race logistics) it can negatively impact your mental state.

I may be smiling, but I was very sick
after this Six Foot Track Marathon.

In recent years, I haven't worried about pre-race caffeine ingestion.  One reason is the negative experience I had in the Six Foot Track Marathon a few years ago, when I was fit enough to do very well for my age.  I drank too much caffeine beforehand and was feeling "wired" by the time the race started.  I never felt good as the race progressed and had difficulty in drinking fluids at the feeding stations.  When I finished, I felt very sick, though didn't accept offered medical assistance.  I just sat in a corner for two hours not doing anything until I felt my equilibrium begin to return and I could start sipping some fluids.

I don't doubt that there are benefits as the research has shown, but to get them, there are factors such as runner weight, usual caffeine consumption, timing, etc., that need to be accounted for in developing the optimal plan.  Now that I'm sticking to my new caffeine-limited regime, I doubt that I'll worry about taking pre-race caffeine.  In fact, I have always felt that if you train over the distances you plan to race, your body will adapt to become more efficient at fuel stores and sourcing anyway.  The more you depend on some pre-race rituals - caffeine ingestion, carbo-loading, sleep - the more likely you are to come mentally unstuck if you can't follow them as planned.

I ran a variation on my usual post-track session 11km this morning, running the length of North Avoca beach and the steep climb up Coast Road instead of the usual climb up Tramway Road.  I felt fatigued right from the start, mostly in the legs, so took it easy.  I have a demanding running schedule for the next three days, and the fresher I can be tomorrow, the better.

Ouch!

Not good news!

After two months of no running, and despondency about my health problems, I know I have put on some weight.  The shorts are a little tighter, as are the T-shirts, and I can't see as many ribs in the mirror.  Up until today, I had tried not to worry about it too much.  Dealing with health concerns and the inability to run were stress enough without beating myself up about my eating or weight (see my blog post about Compensatory Eating).

On Saturday I managed to run 14km, and have now run every day for nearly two weeks.  Although not out of the woods, health-wise, it's time to get back to normal.  "Normal" includes weighing myself regularly and trying to stay at, or below, 68kg.  Not only do I feel healthier at that weight (and my clothes fit better), but it reduces the chances of injury.  I do have a chronic right knee problem (see post titled Adaptation), and it has been quite sore since I resumed running.  I firmly believe that weighing less will alleviate some of the strain.

Much faster and lighter at Croydon in the UK in 1975.

Anyway, after my run this morning, I stepped on the scales for the first time in over two months - 74.0kg!  It was demoralising to see this number, and a big wake-up call.  Even though I can't run the kilometres I would like, I can exert more discipline over what I eat.  It's time to get back onto my "no snacks, no desserts and no second helpings" diet with small breakfasts and lunches.  Occasional treats will be allowed, but I need to be much more strict overall.

My 5km run was a little faster and more comfortable this morning, though my right knee hurt and I'm still running slowly.

Caffeine

45mg of caffeine in my
favourite tipple

Early in my running career I consumed quite a lot of caffeine.  In my twenties, I routinely drank six or seven cups of strong coffee a day, including a cup just before bed which didn't seem to affect my sleep.  At 150mg of caffeine per cup, I would have been consuming about 1000mg of caffeine per day, way above the recommended daily dose (600mg according to the New South Wales Health Department).  At some point, I decided that this was a bad thing because on weekends, when I didn't consume cups of coffee as regularly as when working, I tended to get headaches.  I went "cold turkey" and after two weeks of mild headaches and irritability, the addiction was gone and I did feel generally better.

My running regime makes it important to drink large amounts of fluid, and I have got into the habit of always having a drink at hand.  It's easier to keep hydrating if you enjoy the drink and I have never enjoyed drinking just water.  For a few years I managed to stay caffeine-free, drinking decaffeinated coffee and soft drinks, but when I began my expatriate working life in 1987, and was constantly travelling to different countries, these were not always readily available.

Gradually I settled into accepting the caffeine content of diet colas (Diet Coke seems to be available in most places), which I enjoy drinking (way too much, according to my friends), and trying to limit the consumption to about four cans a day.  I also accepted the occasional coffee.  This would have added up to about 200mg to 300mg of caffeine a day, not an addictive quantity and within the recommended daily maximum.

My "heart-starter" in the last 10 years has been my
pre-run cup of strong black coffee (~175mg of caffeine)

After retiring from work in 2003 and joining Terrigal Trotters in 2004, I changed my regime to having an early morning strong cup of black coffee when I got up and before going for my early morning run.  It helped wake up my body at a time when advancing age seemed to be making the early miles of any run harder and harder, especially the Trotters' 6:00am, or earlier, starts.  I calculate my morning coffee as having about 175mg of caffeine, which is quite a large dose, and though it had the desired effect of pumping me up for the run, it was not always a pleasant feeling and I could often feel veins pulsing in my temple.

The reason for discussing caffeine now is that my research has shown it can be a risk factor in the Atrial Flutter with which I have been recently diagnosed.  Although not the likely cause in my case, it has been a trigger for me to reevaluate my caffeine intake.  My sense is that eliminating the strong early morning coffee and limiting myself to four diet colas a day (or 200mg of caffeine a day), will be a positive move, and that is what I did from last weekend.  I noticed a head-achy feel the first few days and then yesterday morning, after a very early start for the Thursday track session at Terrigal Haven followed by a 10km walk, this developed into a full-blown migraine that had me in bed from about 1:00pm through to 7:00am this morning.  I can't say that it was a withdrawal headache for sure, and given the clots in my bloodstream and the Warfarin I'm taking, there's always a nagging concern it could be something more sinister.  However, today I feel a bit better, though my weekly INR test this morning showed my anti-coagulant level is significantly above the target range (4.8 when it should between 2.0 and 3.0) and I wonder whether this was a factor somehow.

Caffeine is a legal stimulant and research has shown benefits to long-distance runners.  I have experimented with its use and will talk about that in a future blog post.

Hydration

Reaching for a sponge at a drink station
in the inaugural Melbourne Marathon
 in 1978 (2nd, 2:23:06)

It warmed rapidly today, so the small group of us who set out for a long run on local roads at 6am (the first day of Daylight Saving), were glad of our early start by the time we finished.  It was to be my last long run before the Melbourne Marathon next week, and another good test of my fitness level.  The run went well and I felt like I could have kept running when I finished, giving me confidence that, if I run sensibly next week, I won't disgrace myself.  My right knee got quite painful at times, but this was expected.  I was the only one of the group not carrying any fluids for the run, though I did have $10 in my pocket in case emergency hydration needed to be purchased along the way.  As it turned out, I did not need a drink during the 2:56 the 32.5km took me, and wasn't even that thirsty when I finished.

I don't like carrying gear, including fluids, nor do I like stopping during long runs to drink.  Maybe I'm a prima donna, but I find even short stops can break my running rhythm, and there have been times when this has cost me in an event.  My own layman's theory of hydration for distance runners, based on an experiment of one, is that the more long running you do without frequently hydrating, the more your body adapts by "camelling up", i.e., storing fluids in the body in anticipation of the next long run.  It's the same theory that applies to the muscles storing glycogen in response to repeated training runs.  It seems to be common sense to me that the more you do something, and the more you press against the edge of your body's envelope, the more your body adapts to the increasing load.

This morning's long run took in a roller-coaster section
of the Ridgeway

Of course, the trick is not to "tear the envelope", by pushing too far.  I have definitely finished training runs and races seriously dehydrated and in difficulties, though have never ended up on a saline drip.  If conditions are warm to hot, or you are running for many hours, you have to drink or you will cause yourself harm.  I am not advocating a "no drinking" policy and recognise that every individual is different and needs to find their own balance.  However, I would argue that runners who drink frequently in benign conditions are missing an opportunity to train their body to "camel up" and are condemning themselves to carry and/or stop for more fluids in races.  A side effect is that your stomach then has to do some work processing the fluids into the blood stream.  It seems to me that if you can avoid the need for this function, you are likely to run better.

In my best running years, I drank very sparingly during marathon races unless it was hot.  Usually, I would put out plastic sauce bottles containing some flat Coca Cola at each 5km feeding station.  Then I would run through, grab the bottle, and take a couple of well-spaced mouthfuls before discarding it.  If I didn't feel thirsty, or it was nearer the end of the race (does the body really process fluids into the bloodstream in any meaningful way in the last 30 minutes of a race?), or I was in a pack of runners making it difficult to get the bottle, then I wouldn't take a drink.  On average, I would have been lucky to drink a total of more than 400ml during marathon races, and sometimes nothing at all in cool conditions.  I was much more inclined to pour water over myself from a sponge or cup to keep cool.

Of course, for your body to "camel up" between runs, you have to drink a lot of fluids, and I do.  In my case, and I take a lot of flak for this, it's mostly diet colas with some fruit juice and black coffee thrown in occasionally.  Almost no water!  In total, about three litres of fluid a day.

Compensatory eating

When cycling all day, as was the case during my Round Australia
record attempts, the "Big Breakfast" was a daily feature of my
diet, with no weight impact.

The last three weeks of no running has been a test of my dietary willpower, and I'm starting to lose the battle.  I have never been someone who is naturally thin.....and I like my food.  In my teens and twenties, I didn't worry about what I ate at all.  Youthful musculature and plenty of miles, was enough to keep me at a good running weight.  When I reached my running peak, I began to take more care with what I ate but my best racing weight remained around 64kg, with the lightest I ever remember recording being 61kg.

In my latter years, I have considered 66-68kg to be my desirable running weight, but on occasions, have been as high as 76kg.  If I stop running and eat what I feel like, I can rapidly gain those 8kg, and it takes much longer to lose them again.

A few years ago, it became obvious to me that even when running 80-100 kilometres per week, if I didn't watch what I ate, my weight stabilised around 72kg, too heavy to run really well.  In a somewhat obvious epiphany, I realised that my body was no longer able to support the running necessary to bring down my weight, and that if I wanted to maintain a reasonable running weight and stay healthy for my remaining years, I was going to have to cut down on my eating.

Since then, with the exception of hiking and biking trips, I have adhered to some fairly simple dietary rules - no snacks, no desserts and no second helpings.  As a further measure, I limit the size of my breakfast (usually one slice of toast with peanut butter plus a large fruit juice) and eat it as late as possible, and limit the size of my lunch to one sandwich.  Dinner tends to be larger, but limited to one plate only.  I don't drink alcohol or sugared soft drinks, but do drink a lot of diet cola.  Limited treats (maybe chocolate or corn chips) are allowed after long runs or during trips to the cinema.  I try not to beat myself up if I stray occasionally, and permit limited dietary holidays for Easter, Christmas, etc.

This regime has worked well to keep my weight in the 66-68kg range for most of the last three or four years, but I always struggle a bit when I have to stop running because of injury, and that has been the case this week.  One factor is despondency about my injury and its impact on my Melbourne Marathon ambitions.  Another is the change to my daily routine because of my trip to Melbourne.  It has become very easy to have a biscuit for morning tea, or some dessert after dinner.  Partly, it's because I like my food, but partly it is driven by the need for a "feel good" replacement for the running I am missing.  Of course, the "feel good" part only lasts for a few minutes, while the physical consequences can last a lot longer.

I didn't find time to do my scheduled 5km walk today, but still plan to run and walk 5km tomorrow.  It will be the first running I have done for three weeks.  Normally that would be enough time for a soft tissue injury to repair, but I fear I may have walked a little too much in the first week I had off running.  Time will tell.  I'm confident that if I can resume regular running, then I will find it easier to resume my dietary discipline.  If still hampered by injury, then I will have to give myself a good "talking to" about my deteriorating dietary habits.  It's hard enough to come back from injury.  If you are carrying extra kilograms, it not only becomes even harder, but the risk of other injury increases because of the extra weight you are carrying.
