Blindsided By Beverages

Take a couple of seconds to think about your run routine:

You go out for a run of 30-to-60 minutes, which may or may not include a warm-up or cool-down. You come back to the house, drop your soggy shoes and socks at the door, and amble to the kitchen. Once you hit the kitchen you make a beeline for the refrigerator. You open the door, grab a bottle, can or glass of something cold and wet, and slug it down.

Quick - how many calories did you just take in? Even the most anal-retentive runner, the one who counts every calorie of solid food which crosses their lips, can be blindsided by beverages.

Yes, rehydration is necessary after a bout of running. However, we can - mindlessly - take in more calories over the course of sixty seconds than we burned off in the previous ten minutes. When you start to think about it, it's not all that difficult to see why some runners have difficulty losing those last few pounds. You know the ones - those five pounds which can slow you down by 20 seconds a mile.

That's a minute for a 5K. Closer to ten minutes for a marathon. Ask any marathoner who's come "just that close" to a Boston qualifying time what they would sacrifice for ten minutes. Some might mention a pound of flesh, but it's a little closer to five. Naturally, the issue is one of portion control. When I was the age of my oldest grandchild the largest size soda at the major fast food resturant was the smallest size now; same for the french fries.

And when you look closely at a bottle of the most popular "thirst quencher," you find that the 20-ounce bottle represents not one, but two and-a-half servings. And 130 calories go down the hatch quickly. Very quickly.

I am not saying that sports drinks are bad. What I am saying is that we need to pay close attention to what we eat and drink as part of our training...and I consider recovery as important as any training session on the schedule. There are sports drinks on the market which have more trash than treasure, more empty calories than nutritive value. Some drink manufacturers make claims which can hardly be substantiated and usually come with provisos in small print. Personally, I'm too old to read small print. If I can't read it I probably should not drink it.

When it comes to recovering from the run, I will be the first to say this - slow is best.

Slow down. Read the label. And if you can't read it you probably shouldn't eat or drink what is inside it.

Summer is almost here and it's going to be hot. All of us know to drink more fluids and avoid running in the heat of the day. How should the heat effect our mix of intervals and long runs?

I don't presume every runner knows to drink more fluids; more importantly than this, what fluids to drink. While your kidneys are good at controlling the amount of electrolytes passed in urine, your sweat glands are going to push out electrolytes as well as fluid as part of thermoregulation. This means plain water will do you fine while you're at the workplace, if you have a job where most of your day is spent at the desk. However, plain water can be a little, er, boring to the palate; you're not going to drink what doesn't suit your taste. Sports drinks, such as Gatorade, Powerade, Propel, and so on, are good at making certain you have sufficient hydration; the down side of these drinks are that they have a great deal of high fructose corn syrup, a cheap sweetener, and not so much in sodium, potassium, chloride and other electrolytes, which are the things you need most to be replacing.

Oh, contrary to popular belief, the carbohydrates in most beer are countered by the toxicity of the ethanol. Your liver has to work to process the alcohol and remove it from your system before it can assimilate any carbs. Since alcohol can only be passed through the system by urination, sweat or respiration, like that of caffeine, you'll lose more fluid by drinking alcohol or caffeinated beverages (iced tea, iced coffee, energy drinks) than you would sugary drinks, which take longer to pass through the gut.

You can run during the daytime, but understand that the fluid you lose through cooling your body (sweat) is taken from your blood circulating through your capillaries; that's why you'll see folks looking quite red on a hot day when they've been active. The water loss from your blood as part of the cooling process makes the blood thicker and more difficult for the heart to pump through the circulatory system. Think of it like trying to suck honey through a thin straw, compared to sucking water through the same; it's much harder. Since the blood flows slower through the vessels, it takes more pumps of the heart to move it the same distance it would travel with full fluid volume...oh, did I mention the fact your blood is going to the areas of the body needed most at exercise? That means your leg muscles are probably getting the most blood sent to it, next to the brain. That's a long way to go.

So, hotter and more humid conditions of summertime running mean your perceived effort at a particular pace is going to increase. That's bad news. The good news is there aren't many "important" summer races here. The best thing you can do is continue to run through the year, listen to what your body is telling you, and adjust your effort accordingly. As for track workouts and long runs, I suggest finding a sports drink that replaces the minerals and electrolytes you lose through sweat, and keeping a bottle or two available. You can stash bottles on a long run or get your favorite drink at the local convenience store if carrying a bottle is too much of a problem. If those don't work, then adjust your workout times to take advantage of conditions, or run at places where there are water fountains.Swimming or biking may be a good way to get some exercise this summer since it will be so hot. What's the best mix of swimming, biking and running?

Swimming and bicycling are great cross-training, I like them a great deal because of the reduced impact to the musculoskeletal system. The best blend of cross-training activities depends on your fitness level and amount of time you have available to ride or swim. Borrowing the old phrase "the main thing is to keep the main thing the main thing," there is a limited degree of transfer between swimming, bicycling and running; you need to run if you want to be a good runner. If you bicycle, make certain you wear a CPSC or ANSI-approved bicycle helmet, follow *all* the rules of the road, and (please!) refrain from wearing headphones *in your ears* (there are devices that will allow you to listen to music in your helmet AND hear surrounding traffic).I may want to run a marathon this fall. Is it too early to start training this summer?

Good for you. A marathon will teach you a great deal about yourself; your perceived limitations, strengths and weaknesses. Training for a marathon, especially a first marathon, takes at least 18, and up to 26 weeks, depending on fitness level and goal. If your plan is to do LaSalle Bank Chicago Marathon, around the first week of October, this would be the time to begin marathon training. Before you mention heat as an obstacle, let me remind you of a painfully obvious fact: Chicago in the first week of October can range in temperature from the high 80s (last year) to the high 30s (about five years ago). You never know what conditions are going to be like on the day. There are good training plans available, several of which have been used by ECRT athletes to run personal best times and qualify for Boston. The biggest challenge is not so much choosing a training plan, but to follow it through and make certain you toe the line on the day as healthy as possible. A personal note: Running a marathon while injured is not a good idea.
