Mountain Bike Required

SWEEPS keep track of a specific rider field by riding behind the last rider in that wave. Course Marshals, the Scoring Team and racers all look to the Sweep to gauge where the last rider in a wave is positioned on course. Sweeps must ride a mountain bike with appropriate safety gear and this role may require riding endurance. You only need to be as fast as the slowest rider in the field.
