Safety: Take a cell phone with you and let others know where you are. Snow and ice will increase your risk of fall and injury. Being caught out in the cold without a means of contacting friends or family can increase your risk of permanent injury to your limbs from frostbite.
Protect your skin: Your skin will take a beating from the cold. Use Vaseline over your face and thighs. The Vaseline will help to protect the skin from the cold and will keep the clothing from rubbing against your skin and causing sores.
Running in the wind: Running in the wind can be a real chore. Start your run out into the wind so as you are tired coming home you’ll have the wind to your back. Check the weather before you head out for the wind chill factor. If the temperature dips below zero or the wind chill below 20 below zero use the treadmill instead.
