How do you stay safe running in winter?
Stay safe running in winter by choosing cleared, lit routes, wearing traction on icy days, dressing in layers you can adjust, and making yourself visible in the early dark. Keep your phone warm in an inner pocket, since cold can shut a phone off early. A slip on ice can leave you hurt and cooling fast, so share your location and set a return time. Holler alerts your Guardians if you do not check in.
Winter running checklist
01Plan for ice, not just cold
Shaded corners, bridges, driveway aprons and the edges of puddles that melted at noon are where ice waits on a morning run. Pick routes that get plowed and salted first, shorten your stride on slick patches and land with your feet under your hips. On icy days, slip-on traction cleats or screw-in studs on an old pair of trainers give real grip; take cleats off before running on bare pavement for long, where they wear and skid.
02Dress in layers and cover the extremities
A wicking base layer, a light insulating layer and a wind-resistant shell cover most days. The National Weather Service advises loose layers you can remove before you sweat, covering exposed skin, and mittens over gloves because they keep fingers warmer. Start slightly cool, since you warm up within the first mile, and run the first half into the wind so the sweaty return has the wind at your back.
03Be seen in the dark
Winter pushes many runs into darkness at both ends of the day. Wear a headlamp and reflective or lit gear on your ankles and wrists, which move and catch drivers' eyes. Snowbanks shrink the shoulder, so face traffic and step onto a driveway when a car comes. Our winter running safety guide covers lights and routes in detail.
04Keep your phone warm
Apple says iPhones work best between 32 and 95°F and that very cold conditions can temporarily shorten battery life or shut the phone off. Carry it in an inside pocket against your body, start with a full charge, and do not trust a phone showing a low battery on a cold morning.
05Share your run and set a return time
If you fall on ice and cannot get up, the cold becomes the danger. Share a live link with a Guardian and set a return time. If you have not checked in five minutes after it, Holler sends them an overdue alert with your location. The server keeps the clock even if your phone dies.
06Know the signs of cold injury
The CDC lists shivering, exhaustion, confusion, fumbling hands, memory loss, slurred speech and drowsiness as hypothermia warning signs, and it can happen above 40°F if you are soaked by rain or sweat. Frostbite shows as numb, white or grayish-yellow skin that feels firm or waxy. Get somewhere warm and out of wet clothes, and call 911 for confusion, drowsiness or a body temperature below 95°F.
Related questions
Is it safe to run when it is below freezing?
Many runners do, with the right layers and a route that is clear of ice. Wind chill matters more than the thermometer: the National Weather Service gives the example of 0°F with a 15 mph wind feeling like -19°F, cold enough for exposed skin to freeze in about 30 minutes. On days like that, cover your face, shorten the run or loop close to home.
What if my phone dies in the cold mid-run?
Your live link stops updating and Guardians see the last known location with how long ago it updated. Your return time still runs on Holler's server, so they get an overdue alert if you do not check in. Charge fully and keep the phone warm to avoid it.
Should I run on the road when sidewalks are icy?
Roads may be clearer, but drivers are also skidding and have less room with snowbanks. If you use the road, run facing traffic, wear lights, and step off when cars come. See running alone at night for more.
What should I do first if my fingers or face look frostbitten?
Get indoors. The CDC says to warm the area with warm, not hot, water or body heat, and not to rub it or use a heating pad, stove or radiator, because numb skin burns easily. Frostbite should be checked by a healthcare provider.
