Call this a break, traveling and trying to get workouts is one of the hardest things to do in the winter. Well About.com has a great article on running in the winter, from staying hydrated to sunglasses to keep the glare down. Some things that it does not cover is traction and how to stay upright. I like to run off the beaten path so check out YakTrax they make one called the Pro that is made for running in the snow. Anyway About.com article is a good start to making sure you are not left out in the cold.
