Mount Diablo Challenge

October 3, 2021 @ 7:30 am PDT

We are pleased to announce that the Mt. Diablo Challenge will be held on Sunday, October 3, 2021 and is dedicated to 86-year-young cyclist, Joe Shami (photo right). His love of Mt. Diablo led him to climb it 600 consecutive weeks. It also led to his nickname “The Legend of Mt. Diablo.”  While we may have lost Joe this year when he was hit by a car while on his bike, he will continue to serve as an inspiration to cyclists for years to come.  

October 3, 2021 will be the 38th year that Mt. Diablo State Park will close the road for this epic bicycle climbing event to benefit Save Mt. Diablo and the Mt. Diablo Interpretive Center.  The 11.2 mile, individually-timed ride climbs 3,249 feet to the summit of Mt. Diablo starting up South Gate Road. Mt. Diablo is one of the highest peaks in the San Francisco Bay Area with views of the Farallon Islands and the Sierras. The road is closed for safety and it is limited to 1000 cyclists.  The ride welcomes all ages, abilities, teams and bicycle types.  The first waves ascend without any descending bicycle traffic.  It’s a once a year opportunity to enjoy riding the mountain without cars. Celebrate after the ride with free BBQ, awards ceremony and music.  It’s an epic ride that provides breathtaking scenery while testing your climbing ability.
