Join us and become a sponsor of the iconic Mt. Diablo Challenge Memorial Ride. It is an 11.2-mile, chip-timed bike ride to the summit of Mt. Diablo in San Francisco's East Bay. It is planned for Sunday, October 1, 2023, at Mt. Diablo State Park in Danville, CA. The park is closed to cars for this event for the safety and enjoyment of riders. The event is open to riders of all ages and abilities. Elite riders compete to be crowned King or Queen of the Mountain. A celebration follows the ride at nearby Oak Hill Park. The celebration features an awards presentation, BBQ lunch, Cheers garden, live music, and vendor fair. About 800+ riders, 100 volunteers, 300-400 friends and family are expected to attend the celebration.  

The Event will be heavily promoted in traditional and social media and cycling organizations, helping sponsors reach a local, regional, and national audience. There are multiple sponsorship opportunities available from $15,000 to $2,500. Half of the net proceeds from the event will be donated to bicycling safety and conservation on Mount Diablo.
