Before The Damage Is Done...Drink

If the casual observer were to look at me after a workout they would wonder if I had been doused with a fire hose. Doesn't matter what time of the year (save for the coldest weeks), what distance, or what intensity. I still am soaking wet. My college cross-country coach, my wife, my athletes and my friends all marvel at what has politely been described as "a very efficient cooling system."

I used to joke, "I sweat when I think." Who would have considered that to be true? I didn't, until I started looking closer at thermoregulation. Our skeletal muscles (including those muscles used for running), liver, heart and our brain all generate body heat. On those days when we're hotter than our surroundings we can radiate heat (think about those infrared scopes used by military and police to observe in dark conditions) to maintain a proper temperature. When the air temperature is hotter than us we absorb heat. Add to the outside heat the heat we generate from our running, and thinking about running...you are thinking about running, right...?

External heat and internal heating can raise our body's core temperature to a point where our brains have to make a command decision; how long can the body go before vital organs are injured? Our brain decides to start shutting less important functions down in order to protect itself, the heart and other vital organs. That usually means skeletal muscles take the hit. Entire muscles don't get shut down entirely, mind you, but a few fibers here and there at first...which we usually recognize as breaks in running form or decreased range of motion (shortened, choppy strides). As the temperature continues to increase the brain becomes more concerned and shuts down more muscle fibers ("is that my calf cramping?") until we decide to either cool things down by slowing down, drinking cool fluid, getting into a cooler environment or stop exercising altogether.

So it's important to keep the core temperature as low as possible, either by deflecting radiated heat from the sun and other surfaces, or by drinking so you can continue to sweat.

Runners who sweat heavily, naturally, will need to take in more fluid per hour. You can determine your sweat ratio by stepping on a scale (naked) before and after a run and looking at the weight difference, adding the volume of fluid you drank during the run, then doing the mathematics to figure out the ratio per hour. Hotter, more humid days might demand more and colder days less, but you'll have a ballpark figure on which to base your hydration plan.

After the run, it's important to begin the recovery process by replacing the fluids lost. Again, the easiest way to know how much is by stepping on the scale to find the difference in pounds between when you started and when you got done. Multiply by 16 to get the number of ounces, then start replacing fluid on a one-to-one or a one-and-a-half-to one ratio.

Naturally, the next question is "what's the best drink?" Water has been the ideal beverage for many years, and works great for most athletes, but an entire industry has developed in the past four decades because of this question. Sweat not only contains water but minerals, lactate, urea and some trace elements. The most common elements found in sweat are the electrolytes; sodium (average 0.9 grams per liter), potassium (average 0.2 grams per liter), calcium (average 0.015 grams per liter) and magnesium (average 0.0013 grams per liter). These values naturally will vary from person to person.

One of the most popular sports drinks on the market provides .4-.5 grams per liter of sodium, .125 grams per liter of potassium and 200-to-220 calories of energy per liter from carbohydrates. There are sports beverages on the market which have protein, others have electrolytes but no carbohydrates, and some include other trace minerals like chromium. This ideally allows the athlete to make up for some of the lost minerals and nutrients before the workout or race is over. The best sports drink, however, is the one which the athlete will actually drink; all the beneficial elements and chemicals a laboratory can offer (whether or not they truly help!) are of little use if the flavor of drink is terrible.

So don't forget to keep that bottle of water or sports drink handy during your runs, or make certain your run routes have places where you can get (or stash) fluids. Drink early and drink often; if you wait until you feel thirsty the damage has already been done.

The Bow That's Continually Bent...

I vaguely recall a story which ( believe) was written by Eusebius, Origen, or one of the early writers of the Christian Church, about St. John (please keep in mind this is from a text I read back in my former life as an aspiring pastor). (I guess) there was a philosopher who went (in disguise of an outdoorsman/hunter) to visit John later on in his life, & was amazed to find him sitting in relaxation stroking a partridge. He asked John about the frivolity of his present activity, to which John responded with a question of his own. 'I see you have a bow in your hand. Do you always carry it about unstrung?' The philosopher replied, 'yes, if I were to keep it continually strung the tension would weaken the bow & I would be unable to use it to down stronger prey when the time came.'

John replied, 'worry not about my present state of relaxation. As you have rightly said, "the bow that is continually bent will cease to shoot straight."'
So, I guess it's necessary for each of us to take time away from our pursuits in order to recharge, redirect, reevaluate, & sometimes even reacquire a perspective we once had or discarded. The hard part is what I like to call a painfully obvious fact: The more time we have away from working out, training, running, bicycling, swimming, just plain flat-out doing, usually provides us time & opportunity for stoopid things...those things which get us in trouble.
And if you're not careful, you can burn up those spousal approval units during down-time, when you probably should be earning them by doing those quality time things. I've found a few of those QTTs can also provide some much-needed perspective on how other people see us...us being defined as athletes, coaches, & athletic event participants...I guess even athletic event providers can be fit into the definition. And I have to admit the first week or two of I'm not getting up early to... is pretty nice, but after a while it does become a nasty little habit. Sleep, as my wife has told me, is one of her guilty pleasures in life. In the past month I've probably increased my sleep time to nearly ten hours a night, much to my d-a-w-g's displeasure.

But worry not...this is the end of the month & I truly intend to be back on the chain gang.Honestly, it has been nice in many ways. Unfortunately, it also means I've spent lots of time on activities which are simple, but much higher in impact (more running, less cycling or swimming). So my body has really had a tough time adapting to a decreased, but different form of stress.

On top of all that, the temperature has gone not so much through the roof as much as it has increased a minor amount. But, the humidity in our area has definitely gone up. Much harder to breathe when you feel like you need gills. Must scale back effort levels or move indoors for a time. That means more boring. I know many who take the entire summer to unbend their bow. While it might work for them I'd rather loosen the string some rather than take it off completely. That way I'm not looking for the notch when September arrives...believe me, it cannot arrive too soon.

ManBearPig Has Left The Building...

...I'm super serial! Well, I would have rather started this with a comment; in fact, I think I will. This last fortnight (that's a two-week period for those of you who graduated from a high school in Florida) has made me want to scream the same words I was greeted with by my friend Betsy when we showed up for Jackson Day, some 40 days ago...
Global warming, my @$$.
Of course, I'm certain the recent temperatures haven't cooled the ardor of my NOLA friends for their Mardi Gras celebrations, which would have taken place yesterday. Ever wonder what the difference would have been between if the Saints hadn't won the NFL championship & the way things are? According to what I recall from NPR, the city was going to celebrate, win or lose.

You have to love a city that can plan a parade in nothing flat. Ask my friend Betsy.
Now that we are in the Olympic fortnight there's plenty of sport to watch on the television. This can be a good thing if your training is focused on indoor stuff, like treadmills & elliptical trainers. I don't care what's on...it could be curling & I'd watch. I kind of draw the line at ice skating & ice dancing.

But, if you're doing track workouts & long road runs in preparation for a longer target event, say a marathon or a half-marathon in the next two weeks to a month...you fight the seemingly irrational desire to watch men beating each other with sticks (My joke term for ice hockey, a sport I have loved since I was old enough to watch televised games...thanks, Dad!) or chicks on ice (luge - as Robin Williams joked, let's not even talk about the two-man luge...'boys, get a room...'). I tip my (stocking) hat in the general direction of the folks who get out in the chill to plod out lap after lap on the track at the university...in the dark. Every time I see a jogger step onto the track & immediately go into what I would call a flamingo stretch I wait to see whether they're going to crash @$$-over-tin cup to the surface. There are easier ways to stretch that quadriceps, dude.

There's where the spinning instructors could teach joggers a thing or two; use the bench as a stretching aid, & don't stretch far beyond your range of motion.
Giving up anything for the next 40 days? Steven, Beverly & I started talking a little about it on the way home from Auburn Masters...obliquely. The discussion was more about cutting back on beer intake in the hope to drop a little extra weight. I go from no beer an evening to two or three an evening every couple of days. Perhaps a little consistency - one or two a night rather than zero, then three or more, then zero - might be a better thing. It's hard to say, & difficult to forecast; especially when you have friends who love the hop.

However, there are two things I want to drop off the buffet tray altogether, & this time period might not be a bad on in which to give it a jump start. I talked before about wanting good ab days; the goal was to put french fried anything on the verboten list. So, I'll be mourning for Mickey D's best offering, & Sonic's tater tots, as well as any other french fry-like products, until Easter. I was able to cut out mayonnaise this way a long time ago (I do mayo every so often, but not like I used to!); perhaps I can moderate or elminate my lust for pommes frites. Soda pop is also ix-nay, but it's small potatoes since I drink maybe 24 ounces a week of the stuff...at the most.
So, maybe lenten resolutions are little more than a re-resolve on the part of many folks; a mini resolution, or a step toward the inevitable new years' ones we consistently fail & try (Typed 'tri' the last time...am I thinking about the multisport thing, or what? What would Freud have to say?) over & over again.

What do you think? Is it better to try, fail, & re-try...or remain content with the status quo? I put my money on trial, screw-it-up, & do it again.

Baby, It's Cold Outside

Hear that thump? If you didn't figure it out that's the sound of the mercury hitting the floor. Most of my friends & loved ones live in less-temperate climes; they are not showing any love. I can guess why; we don't get near the cold they get, & definitely not the snow.
As much as I hate the dark & cold this time of year, the colder temps mean we get to change our favorite meals from salad to stews & soups. Much, much easier to prepare, even for a culinary-clueless clod like me. Stop by the local grocery & grab up some more vegetables for chopping, or stew beef, or chicken breast filets...nothing like a nice hot stew with a large chunk of Panera asiago cheese bread (and a cold beer!) after a workout.
A couple of weeks ago when the first real cool morning occurred, we heard thumps every few minutes on the window of the pool where I train. At the end of the workout, I saw the lifeguard walking outside with a stick or something, trying to pick up the birds who managed somehow to commit suicide by flying into the window. Flying toward the warmth? Not certain.
The other evening, our 'hound decided to climb up on our bed while we were in a state of repose. If the dog were a small breed, like a pekingese, it would not be such a bad thing. However, we're talking about an 80-pound greyhound. All right, I know he has zero body fat. He also learned the behavior from his "uncle" Steve; when Rubin stays over for the weekend, Steve lets the dog share the bed with him. In light of the $90 gas bill from this last month, the dog might spend more time at the office. Now, though, we have to keep more blankets at the house, think about a better dog bed, or break the dog of this new habit. Or perhaps just suck it up & fire up the furnace. Perhaps after Thanksgiving.
I almost have the missus sold on the benefits of cycling arm/leg warmers. She borrowed a pair of mine the other evening at the track, & did like them save for the painfully-obvious fact my arms are a little larger than hers...so they kept slipping down. Beats carrying extra long-sleeved garments & the need to stop and pull the suckers off, in my humble opinion. Just wear a good short sleeve, & pull the arm warmers down to the wrist when you get too warm.

Winter Running, Florida-Style

And yes, that is snow in there. That's Ski Dubai, the only place in the UAE where you might find the (once again, a John Parker quote) white stuff that falls from God. You have to see it for yourself to believe it really exists, namely an indoor ski slope, toboggan run & refreshment lodge in the middle of the desert...all right, how about in the middle of a shopping mall in the desert...with a Krispy Kreme on the ground floor. But I digress from the topic on which I really wanted to write. Returned home from Dubai last Sunday, where the average daytime temperature was closer to 85 than it was 65, the average here in the Redneck Riviera. Before I am accused of complaining about the lack of culture or temperature here at this particular time, let me say I like running in the autumn & winter here in the Florida Panhandle. Most of my friends from around the Northern Hemisphere, in the continental US and Canada, would give their eye-teeth to have nearly year-round training which we here take so much for granted.
Most of the locals here, from my own observation, tend to shut down their training when the conditions are too hot or too cold for their taste, which leaves a window of about two weeks in the year where they get any quality time in. Ah, but that's a personal problem and an unintentional dig. Those of you who feel offended can get in line because I have many persons to which I owe mea culpas.
It's much like my work place...I prefer to have the air conditioning working in full effect because I can always add clothing if things get too cold...which to me beats sweating like a pig. But again I digress. The challenge of running during this time of year is knowing how much clothing to have on, the ability to adjust on the fly for conditions, and portability. I have written on this particular topic before; marveling at the locals who dress more like Nanook of the North at a road race when the temperature drops below 60 degrees...and subsequently overheating at the first mile. Never pretty. After taking a few dollars to invest in cycling arm and leg warmers, I would highly recommend them for running use. Especially the arm warmers. They can be rolled down around your wrists when the conditions are more temperate, or pulled back up when you begin to catch a chill. The use of bicycle-style tights (4-to-8-inch inseam) and removable knee warmers, or knicker-style tights are a happy alternative to worrying over whether to wear running shorts or long tights. Once again, around here, the need to use long tights only comes probably about three to four weeks through the deadest part of winter. Hats (almost a must, as you can retain more heat from your head this way) and gloves are also helpful, especially if your hands and ears get cold easily. Let your conscience be your guide.
Two more items to consider, make that three: Lights/reflectors, glasses, and hydration. Few of us have the opportunity to run during the middle portion of the day and use that decreased amount of daylight, so most of the runs are going to be in conditions that are dark, or near-dark. An ounce of lighting and reflection is worth a pound of pounding from a local driver heading to or from work who is not paying attention to what's going on around them. Pay close attention to drivers, and prepare an escape plan at all times during your run. A pair of sunglasses with interchangeable or photochromic lenses, preferably polarized, will also help cut down the glare of headlights and the effects of sunlight (different from summer conditions). Lastly, don't forget to hydrate, especially important as you won't feel the need to do so like during summer time. However, you still are losing water to perspiration and water vapor from breathing. Just because you're not sweating like you did during the summer doesn't mean your body isn't regulating its core temperature any less.
See you on the track.

My Motivation, and Some Questions

The Lower Half of (Tom Gilbert's) Six Boxes (Motivation, Skills, Training):
Doggone. The temperature went up two degrees in the space of time it took me to think about how I was going to start this piece (originally scribbled 19 July 2008). For those who need a more objective measure, that was approximately one minute, from 6:48 to 6:49 a.m. And yes, I'm feeling less than motivated to head out to the track this morning.
Wait a minute. Coach Mike, unmotivated?
It's not just the heat or the bugs that makes me think twice. I have no races planned for the next four months, so I'm doing a long (boring) cycle of base training; swimming two or three times a week, bicycling once a week, and running as often as weather and other conditions permit. When you don't have anything on the immediate horizon for which to prepare, the forecast of working out alone (especially when base or maintenance training) can make any athlete reconsider their workout.

Sure, there are times you need to suck it up and go out, regardless of what your friends are doing. But it's nice to know you are not the only one suffering through a workout. Sometimes that's the only saving grace; knowing there is someone else insane enough to get up earlier than the rest of the world, or get out and run a few thousand meters of repeats with you while the rest of the world is at a ball game or concert.
Yes, I know we all need to have a life outside of running (or swimming, or triathlon). So, I do appreciate the athletes I train who take time out of their week (or weekend) to slog along with me. The prospect of seeing them at the track (during the week) or at the seashell (mid-week or on the weekend) gives me one more good reason to get out and run.
ASK THE COACH:
Do you have any thoughts on stretching?
I think a lot about stretching (some of my thoughts are printable!), but I don't do much more than work on my achilles tendons. Some runners prefer to not stretch and never have, others do it religiously. If you're going to do it, I would recommend two things:
First, don't stretch unless your muscles are warm, following at least five minutes of activity. A cold muscle will not stretch, and is more likely to tighten up more if you try to stretch it cold.
Second, stretch gently and naturally, with slow, smooth movements. You can stretch without throwing your leg up on a countertop, bleacher bench or trash can. Stretches which keep your feet on the ground are better. Those 'throw-your-leg-on-the-bleacher' stretches are probably going to instigate the stretch reflex, and you'll end up with a muscle that's more tight than when you started.
For this weather, do you have any particular sport drink recommendations? For those of us on a tighter budget, does water work just as well keeping us hydrated?
Water works great for hydration. It has no calories and no evil after-effects, unless you're running for four hours and you run low on electrolytes, but that's another issue. If you're running for no more than an hour and you can stand the taste (or lack of taste), water will do well.
However, once you get beyond an hour of exercise, you need to think about replenishing carbohydrates and electrolytes. Depending on weight and intensity of activity, you'll need between 30 and 60 grams of carbohydrates each hour; that's 16 to 32 ounces of Gatorade (200-400kcal). If you drink Accelerade during that same activity it will take 18 to 36 ounces (150-360kcal) to replenish, and you also get 7-15 grams of protein with the deal.
My recent favorite sports drink is PowerBar Endurance Sun Tea formula; I picked up a canister at Running Wild after a friend’s recommendation. A 16-ounce serving contains 42 grams or carbohydrates (so 12-24 ounces per hour), plus 480 mg of sodium and 25mg of potassium, so I don't have to worry about electrolytes. On top of that, there's 25mg of caffeine and a very light flavor. It mixes well and doesn't leave any gunk in your bottles, either.

Suzanne doesn't like Gatorade or Accelerade at full strength, but she liked the taste of PowerBar Endurance at normal strength. If caffeine isn’t your cup of tea (pun intended), PowerBar Endurance also comes in Lemon-Lime and Fruit Punch.
The best thing you can do is find a drink that meets your needs and stick with it. I can justify spending a little more for a good sports drink when I know it will help me perform well in workouts and on race day.
We've been told to take it easy this summer until it gets a little cooler. How easy is easy, and come fall, how long does it take to recover our strength and get back into racing form?

Just like the workout regimen, easy is in the eye of the beholder. I can tell usually by change in form or footstrike when an athlete is fatigued. Your challenge is to know it for yourself and to be smart enough to back off or pull the plug.
Being in racing form is not a question of how long as much as a question of when. You cannot be at maximal fitness throughout the entire year. You can maintain base through the entire year by running long, aerobic mileage. But the question of racing form is a function of how developed your base is, what variety of speedwork (tempo runs, short specificity, long specificity) you've put in, and how gradual your buildup is intended to be. Longer, more gradual build-ups lead to higher and more extended peak periods of six to eight weeks. Shorter, steeper build-ups lead to lower and shorter peaks.
Ask yourself, 'What is my goal race?' 'How am I going to get there?' 'What am I going to do to make certain I am at my most ready?'
