Put on some fleecy mittens and a headband and your winter running tights and hit the trails! Winter is a fabulous time of year to work on that next 5k or 10k you signed up for - the outdoor running routes aren't as crowded, and the cold air feels GREAT once you've warmed up and run a mile or two! Pick up some new running shoes at Amazon Fashion (formerly Endless.com) and save $15 on orders of $75 or more of select running shoes with coupon code RUNNER12. Hurry, ends 12/15/2012.
