Running in cold weather is something many beginners fear but experienced runners embrace. Once you know how to dress and prepare, running in temperatures as low as -10°C (14°F) is not only manageable — it can be some of the most enjoyable running you do all year. Empty roads, crisp air, and the satisfaction of running while others stay indoors make cold-weather running genuinely rewarding.
How to Dress for Cold Weather Running
The cardinal rule of cold weather running clothing is layering. Three layers work best: a moisture-wicking base layer against your skin, an insulating mid-layer for warmth, and a wind-resistant or water-resistant outer shell. For most runners in temperatures above 0°C (32°F), two layers suffice.
A common mistake is overdressing. You'll warm up within 5 minutes of running, and a run that starts feeling perfect at 0°C will feel uncomfortably hot by kilometre three if you've worn too much. The standard advice: dress as if the temperature is 10°C warmer than it actually is. If it's 2°C outside, dress as if it's 12°C — you'll hit that temperature equilibrium once your body gets moving.
Avoid cotton entirely. Cotton absorbs sweat and clings to your body when wet, which dramatically accelerates heat loss. Stick to moisture-wicking synthetics (polyester, nylon) or merino wool for all layers.
Protecting Your Extremities
Your hands, ears, and face lose heat fastest. These are the areas to prioritise in cold weather. Thin running gloves or mittens are essential below 5°C (41°F). A lightweight running headband or hat that covers your ears is just as important. Once your ears are covered and your hands are warm, most runners find the rest of the body self-regulates well through layering.
Below -5°C (23°F), consider a neck gaiter or balaclava for your face. Running tights rather than shorts become necessary around 5°C for most people, though individual cold tolerance varies significantly. Some runners are comfortable in shorts down to -2°C; others need tights at 10°C. Learn your body's response over a few cold runs and dress accordingly.
| Temperature | Bottom Half | Top Half | Accessories |
|---|---|---|---|
| 10°C–15°C (50–59°F) | Shorts or capri tights | Long-sleeve base layer | Optional light gloves |
| 5°C–10°C (41–50°F) | Running tights | Base layer + light jacket | Gloves, headband |
| 0°C–5°C (32–41°F) | Thermal tights | Base layer + mid-layer + jacket | Gloves, hat or headband |
| -5°C–0°C (23–32°F) | Thermal tights | All three layers | Mittens, hat, neck gaiter |
| Below -10°C (14°F) | Insulated tights | All three layers | Full face protection, mittens |
Breathing Cold Air: Is It Dangerous?
A very common concern among beginners is whether breathing cold air is harmful to the lungs. The short answer: for most healthy people, no. Your airways warm and humidify air rapidly before it reaches your lungs. Breathing cold air during moderate exertion is safe for the vast majority of runners.
However, if you have asthma or exercise-induced bronchoconstriction, cold air can trigger symptoms. Running with a neck gaiter or balaclava loosely covering your mouth pre-warms the air slightly and can make a meaningful difference. Talk to your doctor before running in extreme cold if you have any respiratory condition.
You may notice more mucus production in cold weather — this is normal. Breathe through your nose when the pace allows, as nasal passages warm air more effectively than your mouth. At harder efforts, mouth breathing is unavoidable and perfectly fine.
Watch for Ice: Black ice — nearly invisible ice on pavement — is the biggest safety risk for cold-weather runners. Run on cleared paths, shorten your stride on potentially icy sections, and consider trail-running shoes with more grip in icy conditions. If in doubt, the treadmill is a smarter choice on genuinely icy mornings.
Warming Up in Cold Weather
Your muscles are stiffer in cold temperatures and need more time to reach optimal working temperature. Add 5 minutes to your usual warm-up routine. Walk briskly for 2–3 minutes before jogging, then ease into your target pace rather than starting fast. Dynamic stretches indoors before heading out (leg swings, hip circles, high knees in place) can also reduce the time your body needs to warm up once outside.
Don't skip the warm-up because you want to get the run over with quickly. Cold muscles tear more easily and are more prone to strain. The extra 5 minutes of warm-up is the cheapest insurance against injury in winter running.
After your run, change out of wet, sweaty clothing immediately. Standing around in damp running gear in cold air risks hypothermia, even after a relatively short run. Have dry clothes ready to change into as soon as you finish. For all-season running guidance, see our Complete Beginner's Guide to Running.

Is it safe to run in cold weather?
Yes, for most healthy people. Dress in appropriate moisture-wicking layers, cover your extremities, and be cautious on potentially icy surfaces. If you have asthma, heart conditions, or respiratory issues, consult your doctor before running in extreme cold.
What temperature is too cold to run outside?
There's no universal cutoff, but most running organisations suggest using extra caution below -20°C (-4°F) with wind chill. At those temperatures, exposed skin is at real risk of frostbite. In practice, most recreational runners prefer a treadmill below -10°C (14°F), especially with wind.
Should I breathe through my nose or mouth in cold weather?
Breathe through your nose when you can — it warms and humidifies air more effectively. At higher effort levels, breathe through both nose and mouth. A loose neck gaiter over your mouth can pre-warm air in very cold temperatures without significantly restricting breathing.
Do I burn more calories running in cold weather?
Slightly, but not as much as you might think. Your body does expend extra energy maintaining core temperature in cold conditions, but the difference is modest — perhaps 5–10% more than the same run in mild weather. The bigger calorie factor is always pace and distance, not temperature.
Final Thoughts
The most important thing about running in cold weather is that it is learnable. The principles covered in this guide — from How to Dress for Cold Weather Running, Protecting Your Extremities — give you a proven framework to work from, regardless of your current fitness level.
Start with one change this week. Apply it consistently across a few runs, assess the results, and build from there. Running rewards patience and consistency more than any other input. Show up regularly, progress gradually, and the improvements follow.
