From Wikipedia, the free encyclopedia
A pump track , a small track using as little as 10 x 30 feet of land, is a looping trail system of dirt berms and “rollers” (smooth dirt mounds for pumping) for bicycling without the rider pedaling. The name comes from the pumping motion used by the cyclist's upper and lower body as they ride around the track. The purpose of a pump track is to use this pumping motion to maintain speed around the track without pedaling.
