Mt Diablo Challenge

October 1, 2023 @ 8:00 am - 5:00 pm


Valley Spokesmen Bicycling Club is celebrating the 40th annual Mt Diablo Challenge, an 11.2-mile ride that climbs to the summit of Mount Diablo, one of the highest peaks in the Bay Area. It is a 3,249-foot climb up South Gate Road through Mount Diablo State Park that is closed to cars or cyclists not involved in the challenge. It is the one time of year that riders can enjoy the course without external traffic. The ride starts at Athenian School in Danville, CA, which is a 2.9 mile from the registration location at Monte Vista High School. Riders need to plan check-in times and registration guidelines.

There are various waves, and the first wave often descends as other waves are still ascending. The first wave starts at 8:30 am, and the next waves begin every few minutes. For those interested in using the whole road, please plan to participate in the first waves, as later waves must stay to the right. The end of the ride is a descent to Monte Vista High School, the check-in location, where there is food, drink, awards, vendors, and music for a grand celebration. The final wave of riders is encouraged to descend by 12: 45 pm to join the festivities. Water and food are unavailable during the ride, but options are available for purchase to plan for the festivities after the event. There are no SAG vehicles along the curse, but bike mechanic stations will be at the starting area.

Many types of bikes are unique to this cycling road ride: tandem or single road bikes, fixed gear, mountain bikes, unicycles, and even outdoor Elliptical bikes. Riders can use Class 1 e-bikes but will not be eligible to compete for prizes or awards. E-bikes will start in non-elite waves. Adults with children in a tow-behind are also allowed. Note registration details for bike type and count of children for tow-behinds. Riders can establish teams of at least four riders to compete against other teams for the best combined time up the mountain. Co-ed teams are allowed. Team names are set with registration under Event Questions.

Danville offers visitors multiple restaurant options: Revel Kitchen & Bar and The Peasant & The Pear. Mount Diablo also has many dining options with lodging near the summit. Restaurants like Moresi’s Chophouse and Ed’s Mudville Grill are local owners and open. Lodging options in the area include Embassy Suites, Lafayette Park Hotel & Spa, and public campgrounds like Live Oak and Juniper in Mount Diablo State Park.

Mt Diablo Challenge was previously hosted by Save Mount Diablo but has been taken over by Valley Spokesmen Bicycling Club since 2017 to broaden participation, emphasizing family participation. Mt Diablo Challenge benefits Save Mount Diablo through donations made during registration.
