Try a healthy new way to get to work on National Bike to Work Day! Held annually on the third Friday in May, this movement highlights healthy choices, alternative transportation options and is a win for the environment. Established in 1956 by the League of the American Bicyclist, it was timed to coincide with the arrival of warmer weather. Pump up your tires, don your helmet and hit the road (or the bridge!) this year.
