Cool Weather Running: Thrive in Winter Training


By Roy Stevenson

The long, hot summer days are behind us and fall leaves and cooler temperatures are signs of the short, cold winter days to come. But just because the weather is changing doesn’t mean you need to stop training outdoors. Just read this refresher on how to run in the cold, and get outside!

Weathering the Cold

Reduce your speed. Don’t be tempted to run at your summer pace in the winter. Unique conditions like snow, ice, wind, low visibility and wearing several layers of clothing will slow you down. Running too fast in cold weather often results in disaster—falling on slippery roads causes abrasions, bruises, broken bones and muscle strains—which can put you out of running for weeks! So settle into your steady winter pace and enjoy it.

Watch the terrain closely. Walk around icy patches and be careful while running downhill and around corners. If you find yourself on slippery terrain, slow down to a shuffle, shorten your stride and run flat-footed for more shoe contact with the ground. Stay relaxed and keep your balance.

Cold Weather Running Myths Debunked

Be wary of myths about cold weather running, especially that running will provide the heat necessary to keep you warm in cold temperatures. Given the combination of low body fat on distance runners, the extreme cold and accumulated sweat in clothing, heat loss often exceeds heat produced during distance running; you can easily get hypothermia if you aren’t dressed accordingly.

Another myth is that lung tissue will freeze in sub-zero temperatures with the rapid breathing of cold air. Research by McFadden (1984) found that cold air poses no danger of damaging our respiratory passages. Even in extreme cold, incoming air warms to 26–32 degrees by the time it reaches the bronchi.

But the downside to exercising in cold air is that during the warming process the humidification of cold air causes water and heat loss from the respiratory tract (mouth, trachea, larynx, bronchi). This moisture and heat loss causes a dry mouth, burning throat, irritation of the respiratory passages and dehydration, which can lead to throat infections. Drink frequently to keep your throat moist and to rehydrate after running.

The Chilling Wind

Always consult the Wind Chill Temperatures Chart (nws.noaa.gov/os/windchill) before going out for your trot. It’s not the actual temperature that causes hypothermia—it’s the combination of temperature and wind speed. Cold wind displaces the insulating warm air that surrounds your body while you run, causing an overall convective heat loss.

Running in a calm 30 degrees can seem quite warm, but running in that same temperature with wind gusting at 20 miles per hour will bring the effective wind chill temperature down to -15 degrees, making it dangerous to run. On cold, windy days run out and back courses: head into the wind on your way out, and return with the wind at your back.

Tips for picking Winter running Clothing

Layer up! Wearing layers traps air between the clothing items, which warms up from your body heat. If you start overheating, increase the airflow to your chest by unzipping your jacket. On the bottom, wear microfiber or polypropylene tights. Polypropylene tights are best when temperatures dip below 40 degrees.

Stay dry. Choose moisture wicking, breathable fabrics, like microfiber or wool, which will keep you drier and warmer than cotton.

Cover your head. You can lose up to 40 percent of your total body heat from your noggin, so on wet, cold or windy days, wear a hat or ski mask made from microfiber or wool.

Protect your digits. Keep your fingers toasty with microfiber or wool gloves or mittens. Mittens are better than gloves because they keep your fingers together, so their combined heat keeps your hands warmer. Choose wool or polypropylene socks for your feet.

Stand out from your surroundings. Wear dark clothing to contrast against snow in the daytime and light-colored, reflective clothing at night. Use a large runner’s reflective vest when running at night, dawn or dusk. Improve your safety by wearing a headlamp or reflective leg bands, armbands, safety lights and an illuminated hat. Caution: Even with reflective gear, drivers may not see you in foggy or rainy conditions. Stay aware.

Cold conditions shouldn’t stop you from training outside; you just need to plan accordingly. But if there’s a blizzard, or the temperature dips below zero, keep yourself safe. Take the day off from outdoor exercise and continue training indoors on a treadmill or track.
