National Bike Challenge is a FREE program with the goal of encouraging people to bike for both transportation and recreation. It is sponsored by People for Bikes and Scott Natural. Much like Bethesda Transportation Solutions’ Walk & Ride Challenge, participants in the National Bike Challenge form teams and try to log the most mileage to win great prizes. Bike Challenge teams can have a maximum of ten participants each. Miles are logged either through Strava or Endomondo.
