Bike to Work Day was originated by the League of American Bicyclists in 1956, and takes place on the third Friday in May. On this day, cyclists across the country show solidarity and ride together for their health, their cities, and the environment. Bicycle advocacy groups provide tips and route information to encourage people to try bicycle commuting as a healthy and safe alternative to driving. The holiday is supported by many organizations - from local bike shops and restaurants to municipalities and transit authorities. Further, the American Medical Association has endorsed Bike to Work Day as part of its push to encourage active transportation.
40% of all trips in the U.S. are less than two miles, making bicycling a feasible and fun way to get to work.
