Running in winter: recommendations for intensity
The more intense your training is, the deeper you will breathe in and out when you run. Deep breaths through your mouth can dry out the mucous membranes and irritate the bronchial tubes, especially in the cold winter air. Intense training sessions such as interval or tempo runs put too much strain on your airways in cold weather.
Instead, a relaxed endurance run is recommended in winter, during which you can still breathe through your nose without any problems. Cold air takes longer to reach your lungs when you breathe through your nose, however, the air is a lot warmer once it gets to your lungs. A light scarf in front of your mouth also helps to warm the air.
Since you can take in less air through your nose than through your mouth, you should reduce the intensity of your exercise. This will prevent shortness of breath or stitches whilst running.
At what temperature is it too cold to jog?
A bit of drizzle or even fresh snow shouldn’t deter you - but at what point is it too cold to run outdoors, even for seasoned runners? In general, experts recommend not jogging or running outdoors when temperatures drop below minus 10 °C. At colder temperatures, sufficient blood flow to muscles, tendons and ligaments becomes much harder, which increases the risk of injury.
You should check the outside temperature before going jogging and running. This will help you to decide whether it is too cold for a run. For many runners, humidity is also a decisive factor, as the air is clearer, and it is sometimes easier to breathe when the humidity is comparatively low.
Running in winter: how to adjust your warm-up and cool-down
In cold temperatures, muscles take longer to warm up. To avoid injuries and muscle strains, you should plan enough time for a thorough warm-up. Here's what to keep in mind when doing a warm-up and a cool-down in winter:
Make the warm-up a little longer and the cool-down a little shorter than in summer: plan at least 15 minutes for the warm-up and run loosely for about one minute at the end.
Stretch in a warmer place so that you don't cool down too much during the warm-up.
Run slowly before picking up the pace. Overall, your run should not reach the same intensity as in summer.
You can prevent sore muscles after a workout by taking it easy.
After your run, get warm quickly and change into dry clothes to reduce the risk of catching a cold.
