The temps on the weather forecast won’t feel the same when you’re moving. When dressing to run, the rule of thumb is to add 10 to 20 degrees to the outside temperature to calculate your running temperature. Keep in mind that this number is dependent upon your body size, run pace, and the length of your run. But you should also take the wind-chill factor into consideration. When winds are present, look at the “feels like” temperature to determine what to wear.
Once you get moving, your body heats up fast. And once you stop running, you’ll cool down very quickly, so be prepared to get out of those wet clothes immediately upon finishing your run.
Here’s an informal guide for getting dressed to run in any type of weather:
- 60+ degrees: tank top or singlet and shorts (feels like 70–80 degrees)
- 50–59 degrees: short sleeve tech shirt and shorts (feels like 60–79 degrees)
- 40–49 degrees: long sleeve tech shirt, shorts or tights, mittens or gloves (optional), headband to cover ears (optional) (feels like 50–69 degrees)
- 30–39 degrees: long sleeve tech shirt, shorts or tights, gloves, and headband to cover ears (feels like 40–59 degrees)
- 20–29 degrees: two shirts layered—a long sleeve tech shirt and a short sleeve tech shirt or, long sleeve shirt and jacket—tights, gloves, and headband or hat to cover ears (feels like 30–49 degrees)
- 10–19 degrees: two shirts layered, tights, gloves or mittens, headband or hat, and windbreaker jacket/pants (feels like 20–39 degrees)
- 0–9 degrees: two shirts layered, tights, windbreaker jacket/pants, mittens, headband or hat, ski mask to cover face (feels like 10–29 degrees)
