20 Tips to Stay Cool on a Summer Run
1. Try Running Early in the Morning1 of 21
It's the coolest, most serene part of the day, and there's nothing like a morning run to boost your mood all day long.
2. Run Whenever2 of 21
Maybe the morning doesn't work for you. Fine. The long daylight hours make for lots of other options. Meet with a group several evenings each week and save lunchtime for solo runs. Maybe an occasional morning run wouldn't be so awful. Try it and see. Running in winter is more confining simply because there's so little daylight time. Not so in summer.
3. Drink Like Crazy3 of 21
Even if you don't feel thirsty, drink at least 8 oz. of fluid each hour, and more if you're outside or tend to perspire a lot. You'll run better with adequate fluid intake, and you'll feel better, too. By keeping your water storage high, you'll also improve your body's cooling mechanisms.
4. Acclimate With Care4 of 21
You need to acclimate to the heat in a safe and gradual manner, not haphazardly. For the first two weeks of hot weather, do no speed sessions and keep your midday running bouts to 30 easy minutes at most. (You can go longer on cool mornings or evenings.) In 10 days to two weeks, you should be fully acclimated.
5. Go Light and Loose5 of 21
Wear light-colored, loose-fitting clothing. The former will reflect the sun's rays better; the latter will enable you to take advantage of any breeze, including the one you make by running. The new sports-specific synthetics are better than cotton, too. They stay drier and wick moisture better than natural fibers do.
6. Screen it Out6 of 21
To protect yourself from skin cancer and other skin damage, use sunscreen liberally. Do so even on partly cloudy days; harmful ultraviolet rays are not blocked by cloud cover. Another benefit: Sunscreen can decrease your skin and body temperatures, so you'll stay cooler during exercise.
7. Join a Running Club7 of 21
This is a good tip year-round, but running clubs are especially active in summer. Long group runs on the weekend, evening speed sessions during the week, social nights. You'll love the energy and camaraderie of a running club.
8. Maximize Head Room8 of 21
You lose a major portion of body heat through your head, which is bad in winter but good in summer. So on hot days, don't cover your noggin tightly with a hat. Cover it, for sure, but with a loose-fitting hat, preferably made of mesh or some other breathable material.
9. Pour It On9 of 21
There's nothing like the psychological relief of pouring cold water over your head on a hot run. But don't depend on it to keep your body temperature down, because it won't. To help you do that, you need to drink the water.
10. Go Out and About10 of 21
Once every couple of weeks, schedule a run at a nearby park, nature trail or historical park. Bring the family along or go with a running friend or two. Take a picnic with you for after the run, then do some sightseeing.
11. Start Slowly11 of 21
I'm a big proponent of doing this in all seasons, but starting your run slowly is particularly beneficial on hot days. The slower you start, the longer you'll keep your body heat from reaching the misery threshold. If you normally run at an eight-minute mile pace, for example, do your first mile at a 10-minute pace.
12. Head for Water12 of 21
Running near water—whether it's along a river, lake or ocean—is usually cooler and breezier. Urban streams often have paths running alongside of them, if you take the time to explore. And even if the air temperature is about the same, you'll likely feel cooler just being near water.
13. End With a Dunk13 of 21
There is absolutely no better place to start a run than at a pool. Why? Because when you finish your run there, you can take a refreshing dip. Once a week or so this summer, bring your bathing suit and running gear to the pool.
14. Run Fountain-to-Fountain14 of 21
As a fallback for those beastly hot days, design a run that takes in frequent water stops. Water fountains are the obvious choices, but there are many more possibilities. When you map out your route, consider gas stations, health clubs, hospitals, schools, convenience stores and city parks.
15. Make Like a Camel15 of 21
Especially on long runs or trail runs where you'll be away from water sources, bring your own. Use a water belt, pouch or holster for bottles or simply carry it (you'll get used to it). Another option: The night before your long Sunday run, take your bike or car out and stash several bottles along your next day's running route.
16. Heed the Heat Warnings16 of 21
You need to be very sensitive to the warning signs of heat illness, which, if it progresses, can be fatal. If you feel trouble coming on, you need to stop running, find some shade, get liquids and then find a ride or walk home. Following are signs of impending heat illness:
- Headache or intense heat buildup in the head. - Confusion or lack of concentration. - Loss of muscular control. - Oversweating followed by clammy skin and cessation of sweating. - Hot and cold flashes. - Upset stomach, muscle cramps, vomiting, dizziness.
17. Decrease the Speed17 of 21
Do your speed training in the morning or evening. Otherwise, you're really going to put a strain on your system. The heart literally beats faster in high heat, as it's pumping extra blood out to the skin as part of the body's evaporation/cooling mechanism. You won't be able to run as fast, so don't try to.
18. Lower Your Expectations18 of 21
In training and in races, you won't be able to run as fast as you would on cool days. If race day comes, and it's super hot that morning, ease back and treat it as a training run — and drink at all the water stops.
19. Watch What You Drink19 of 21
Both caffeine and alcohol are diuretics, which means they increase urine output. This puts you at greater risk of dehydration. Since hot weather is already causing you to dehydrate faster, be especially careful about your caffeine and alcohol intake in summer. People in my part of the country drink a lot of iced tea. Be careful if you do, as iced tea contains a significant amount of caffeine. An alternative: herbal iced tea.
20. Bag It if It's too Hot20 of 21
Some days are going to be unsafe for running, especially if you live in an urban area where air pollution is also a concern. On those occasions, consider skipping running altogether. Or run inside on a treadmill. Or hit the pool for some laps.
Sure, it's going to be hot this summer. No way around that. But with some planning and a little imagination, you can minimize the downside and make it work for you. Stay flexible, have fun and, above all, be safe.
