To stay warm and comfortable during your winter runs, it will be important to wear layers.
I am sure if you are like me, less clothing is best, but when it get's cold you need to add clothing, and this causes other issues of comfort. Too much clothes and you feel like you are dragging, too little and you run chilly and stiff. So the happy medium is to have either just the right amount of clothing on, or have the correct clothing on.
The best approach is to dress in layers:
1. The first layer should be made of a wicking material to keep the sweat away from your body.
2. The second layer should be to keep you warm and can be a little heavier
3. The third layer should keep the wind or cold air away from you.
