Riders of all ages are welcome to join in this event! Riders can compete on any type of non-motorized bicycle, including tandems, uni-cycles and hand powered vehicles. All proceeds benefit Save Mount Diablo’s land conservation efforts to create a national park-sized wilderness in your backyard for you, wildlife and future generations to enjoy.

For information on the 2016 Mount Diablo Challenge, subscribe to our newsletter and follow us on Facebook!

We photograph, video- and audio-record throughout the event, and by entering the space and joining the gathering you are granting us permission to record you.


Not available in XS

The Save Mount Diablo jersey is available now through our Jakroo storefront. 15% of the proceeds go to Save Mount Diablo to help preserve, defend and restore the Diablo wilderness for all to enjoy. Jerseys can be ordered after the event date and will be recieved by mail.


Thanks to all of our generous sponsors, volunteers, park rangers, the Mount Diablo Amateur Radio Club, and the Contra Costa County Sheriff's department. Without your efforts we could not make this event possible!
