Because humans are warm weather mammals, it’s critical that we keep our bodies warm, especially when running in the cold.
Endurance runners, with their lean build, are even more vulnerable to cold and wet environments. Also important, and often overlooked, is doing regular sessions of stretching and strengthening exercises. Warming up prior to heading out as well as maintaining your carbohydrates and fluid intake levels in cold weather will yield a better and often safer performance.
