treadmill

Last winter, much of the U.S. experienced record low temperatures. 

This “polar vortex” caught me completely off guard and sent me running for the treadmill. 

I’ve vowed to run outdoors as much as possible this winter, no matter how low the temperatures drop. 

This time I’ll be prepared to run in the cold, though. 

Here are our top picks for winter running gear that’s guaranteed to keep you warm.
