Mount Diablo Challenge

October 3, 2021

Mt. Diablo is one of the 3 highest peaks in the San Francisco Bay Area climbing 4000 feet with views of the Farallon Islands and the Sierras. The Mt. Diablo Challenge (MDC) is an 11.2-mile, timed bike race that climbs 3249 feet to the summit of Mt. Diablo up South Gate Road. The ride is open to competitive and recreational cyclists – young and old alike. Mt. Diablo State Park is closed to traffic for this event and the first waves can ascend without any descending bike traffic. It’s a once a year opportunity to enjoy riding the mountain without cars!
