MCRA Challenge Series

MCRA has put together a series of races on 4 different tracks spanning over a season called the MCRA Challenge Series. Races are held twice a day for a total of 4 races over an event weekend.

All riders MUST have a current race license from an accredited race organization to enter the series. All riders will be required to show documentation at the time of registration. Students of the MCRA Race License Clinic will receive a “by” and be able to register for races without purchasing a race license for that weekend only.
