Stay warm!

1. Dress in Layers

Layers provide options when cycling in the cold if the weather warms up or if you are overdressed. A base layer that wicks sweat and keeps moisture away from the skin and an outer layer protecting from wind and precipitation are necessities. In between, wear fleece or other fabric that retains heat. Boot covers that are waterproof keep out snow and slush and keep feet protected. Hats and helmet covers prevent loss of heat through the head. Gloves designed for winter biking keep fingers and hands warm and able to control and brake. Goggles and a face mask shield from wind damage and skin chapping. No visible skin is a good rule to follow. Winter winds and weather chaps exposed skin.

2. Drink Up

Hydration is important even when it's cold outside and you're not as thirsty. Many times athletes forget to properly hydrate when exercising in cold temperatures. Your body requires just as much fluids as when it's hot, but it's not as obvious as in higher temperatures. Get a fluid system that resists freezing in low temperatures. Finding your water supply frozen stiff is a quick way to get dehydrated while winter biking.

3. Don't Risk It

Never cycle when it's icy or temperatures get severely cold. The same is true if a storm is near. It's not worth it to get a ride in if it's risking your life. Either hop on the trainer for a ride or find another indoor activity to get your heart rate up. Wrecking your bike on a patch of ice is a recipe for disaster, for both you and your bike.

4. Be Prepared

Always take a cell phone in case of emergency. Winter weather is unpredictable, so make sure someone always knows where you are and is available to come help if necessary. Leave a map of the route and the time of departure so that if you're not back in a reasonable amount of time, someone can find you. Take an adequate supply of fluid and snacks, and all the normal repair gear you'd take, such as a spare tire, pump and tools.

5. Have Fun

Cold weather cycling is fun. It's a great way to get out of the house and get your exercise at a time you normally wouldn't want to be outside. As long as you take the proper precautions (and exercise indoors if cold weather is severe), there's no need to worry.
