A good rule of thumb: You should feel chilly during the first mile or so of your run. If you feel toasty soon after heading out the door, you're probably going to get too hot and sweaty later on.
Protecting extremities is also a good idea for retaining body heat. Gloves, hats and face scarves can make a blustery day bearable.
Your winter running wardrobe should also include safety accessories like traction systems and reflective gear. Also be sure to hydrate before, during and after your runs to avoid dehydration. Here are a few gear tips for getting the most out of your next winter run:
