Map Your Route
Stable, safe footing should be your priority when planning a winter route, says Andrew Kastor, a running coach in Mammoth Lakes, California (where he lives with his wife, U.S. Olympian Deena Kastor). For early-morning or evening workouts, scout out plowed streets and sidewalks that are well lit, to help you spot black ice. Look for a loop in your neighborhood that you can repeat as many times as you want, recommends Tracey Martinson of Running Club North in Fairbanks, Alaska. That way, if you become tired, slip on ice, or get wet, you will still be close to home and can quickly escape the elements.
Warm Up Wisely
Before any workout, walk around or jog in place indoors for five minutes, recommends Olympian Jeff Galloway, coauthor of A Woman’s Guide to Running. When you head out, give your body time to adjust to the conditions by taking 30-second breaks every few minutes for the first 10 minutes.
Take Cover
Try to avoid open roads and paths near water: Tree-lined trails and city blocks with tall buildings can help protect you from biting winds and snow flurries, says Olympian Lindsey Anderson, assistant track and cross-country coach at Weber State University in Utah.
Cool—Don’t Freeze—Down
To avoid getting too chilled during your cooldown, keep it brief: Slow your pace for three to four minutes, then go inside to stretch. Take off extra layers and keep moving for another five to 10 minutes before showering.
Start Small
If you normally do four miles in the summer, start with two.
“It’s better to underestimate your ability in the cold,” says Martinson. If you have to stop, your body temp will drop rapidly, increasing your risk for hypothermia. Easing into it can also help your airways acclimate, says Burch. In subfreezing weather, it’s helpful to wrap a scarf or neck gaiter around your nose and mouth to warm the air before you breathe it in, says Martinson.
Drink Up
You don’t see your sweat losses in the winter like you do in the summer, so most people give little thought to staying hydrated, says Burch. But you can still sweat just as much (especially if you’re bundled up). Try putting your bottle under your layers to help keep it from freezing
Be Flexible
You may be an a.m. exerciser, but on extremely cold days, your best (and safest) bet is holding off until mid-afternoon, if possible, when temps are at their highest and paths are more likely to be plowed. And yes, there is such a thing as too-lousy weather.
“Stay in if you have to battle wind, snow, ice, and darkness, because there are just too many challenges stacked up against you,” says Kastor
