The National Bike Challenge is a nationwide event uniting thousands of current bicyclists—and encouraging countless new riders. In its simplest form it is a logging center for users to record miles ridden and be part of the national community of bicyclists. It is a free and easy way to challenge yourself, colleagues and the greater community to ride more. Users compete on a local, state and national level. The Challenge aims to unite 75,000 riders to pedal 35 million miles from May 1, 2015 until September 30, 2015. The Challenge is a successful partnership between PeopleForBikes and Kimberly-Clark’s Scott Natural Brand.
