Cold Weather Running Tips
  • Dress in layers – Choose a highly breathable base layer (this is what you should wear the closest to your skin). A wicking material will move the moisture away from your skin, making you feel more comfortable on your run. Wear a looser, second layer of breathable material. Fleece would be a good choice for this layer on a cold day. This adds insulation between your base layer and outer layer. The outer layer should be breathable, wind-resistant, and water-resistant material.
  • Wear a hat – Your uncovered head is responsible for 40% of heat loss. Try wearing a headband if a hat feels too hot.
  • Protect your hands – Mittens are warmer than gloves because the body heat from the fingers warm each other.
  • Wear warm socks – Socks made of synthetic fibers wick moisture away from your skin. Try to avoid cotton socks.
  • Don’t forget the sunscreen – The sun is still strong, even during the month of November.
  • Don’t overdress – Dress like it is 20 degrees warmer than the temperature. You will warm up after you get moving!
