What does proper layering of clothing allow for in cold weather running?

Proper layering of clothing significantly enhances insulation and temperature control, which is crucial for running in cold weather. When runners wear layers, they can effectively trap heat close to their body while also allowing for moisture management. The inner layer typically wicks sweat away from the skin, keeping the runner dry and warm. The middle layer often provides insulation, such as fleece or down, which retains body heat. The outer layer acts as a barrier against wind and precipitation, helping to maintain a comfortable temperature.

By adjusting or removing layers as needed, runners can regulate their body temperature more effectively. This adaptability helps prevent overheating during intense exertion or chills during slower periods. Proper layering ultimately ensures that runners can perform optimally and comfortably despite cold weather conditions.
