There’s nothing like a cool pint after a hot run – and it might even do you good

The problem most runners have, though, is reconciling sinking a couple of cold ones with the consequential effect on their training. However, although we all know the dangers of drinking too much, moderate beer drinking may be better for us than we think.

Here comes the science bit…

Beer, like red wine, does have health benefits. The malt and hops used in both lager and bitter contain flavonoids, which counter cell damage and help reduce the risk of cancer and heart disease.

Beer also contains B-vitamins and chromium, which help in converting carbohydrate to energy; and choline, which, ironically, protects against liver damage and memory loss. In 2003, a review of studies showed that while heavy alcohol consumption increases the risk of a stroke, moderate consumption may lower it. The recommended daily intake for athletes is 500ml (just under one pint) for men and 250ml (just under a half) for women.

There are also benefits linked to recovery from exercise, says nutritionist Kim Pearson (www.equilibria-health.co.uk).

“Beer contains predominantly water and carbohydrate, both of which are essential in post-race recovery,” she says.

 “A recent study at Granada University in Spain found that the sugars, salts and bubbles in a pint can help athletes absorb fluids more quickly than re-hydrating with water.

“The carbon dioxide in beer helps quench thirst more quickly, while the carbohydrates replace some of the calories lost through exercise.”

A little of what you fancy

Moderate consumption is the key to enjoying a guilt-free beer. Use these guidelines to keep you on the straight and narrow:

• A pre-race beer the night before to help you relax is fine, but keep it to one: alcohol is a diuretic and you don’t want to be dehydrated on the start line.
• Drinking beer after a run is a great way to unwind, but match it with plenty of water and healthy post-training snacks (pork scratchings don’t count).
• Drinking lots of beer during a race is a bad idea but a few sips on a fun run won’t hurt you. Just take care not to drink too much as even a small amount in this situation can cause dehydration and impair judgement.

Try to drink organic beers, advises Pearson. “They are produced with far fewer chemical additives, which make them the healthiest option,” she says. “If your local pub doesn’t sell any organic varieties, then opt for a beer that comes from a smaller, lesser-known brewery, as this is more likely to contain more natural ingredients.”

There’s good and bad news about running in the heat.

First, the bad news: When the temperature rises about 10 degrees C, you’re going to run more slowly and feel worse than you will at lower temperatures. But by gradually preparing yourself for increased temperatures and taking action from the beginning of hot weather runs, you’ll get a welcome dose of the good news. You’ll learn how to hydrate yourself, what to wear, and when and how much your body can take in hot weather, all of which will help you recover faster and run better than others of your ability on hot days. While even the most heat-adapted runners won’t run as fast on hot days as they can on cold ones, they won’t slow down as much nor will they feel as much discomfort.

Until the temperature rises to about 65 degrees F, most runners don’t notice much heat build up, even though it is already putting extra burdens on the system. It takes most folks about 30 to 45 minutes of running (with or without walk breaks) to feel warm. But soon after that, if the temperature is above about 15 degrees C, you’re suddenly hot and sweating. On runs and especially races under those conditions, most runners have to force themselves to slow down. It’s just too easy to start faster than you should when the temperature is between 10 and 15 degrees C because it feels cool at first.

As the mercury rises about 13 degrees C, your body can’t get rid of the heat building up. This causes a rise in core body temperature and an early depletion of fluids through sweating. The internal temperature rise also triggers the rapid dispersion of blood into the capillaries of the skin, reducing the amount of that vital fluid that is available to the exercising muscles. Just when those workhorses are being pushed to capacity, they are receiving less oxygen and nutrients. What used to be a river becomes a creek and can’t remove the waste products of exercise (such as lactic acid). As these accumulate, your muscles slow down.

Scheduling
The best time for hot weather running is early morning. The more you can run before sunrise, the cooler you will feel, compared with how you’ll feel later in the day. The second best time to run, by the way, is right after sunrise, unless the temperature cools off dramatically at sunset, which would make that time more favourable. In humid areas, however, it usually doesn’t cool down much after sunset.

Some tips on how to say cool

• Slow down early – The later you wait to slow down, the more dramatically you’ll slow down at the end and the longer it will take to recover from the run. Walk breaks, early and often, help you lower the exertion level, which conserves resources for the end and reduces heat build up.
• Wear lighter garments – Loose-fitting clothes allow heat to escape. Don’t wear cotton clothing. Sweat soaks into cotton, causing it to cling to your skin, increasing heat buildup. Several materials will wick the perspiration away from your skin: Coolmax, polypro, etc. As moisture leaves your skin, you receive a cooling effect, and these types of materials are designed for this.
• Pour water over yourself – Up to 70 percent of the heat you can lose goes out through the top of your head so regularly pour water over your hair (even if, like me, you are hair challenged). Regularly pouring water on a light, polypro (or a similar material) singlet or tank top will keep you cooler.
• Drink cold water – Not only does cold water leave the stomach of a runner quicker than any type of fluid, it produces a slight physiological cooling effect – and an even greater psychological cooling effect. But don’t drink too much either.
