The Save Mount Diablo Challenge, presented by CA Technologies, is traditionally, an 11.2 mile timed bike ride, starting at Athenian School in Danville and climbing up Southgate Road 3,249 feet to the summit of Mount Diablo. We now have a Junction Wave which will end at Mt. Diablo's Junction at 6.5 miles and 1,578 feet elevation gain- great for those building their climbing skills! 1,000 cycling enthusiasts compete and prizes are awarded for several categories in a ceremony at the summit with food and beverages for all. All proceeds benefit Save Mount Diablo’s land conservation efforts.
Thanks to all of our generous sponsors, volunteers, park rangers, and the Contra Costa County Sheriff's department.
Without them we could not host this event.

"Thank you Mount Diablo Challenge for putting on a great event. The event helped me attain a goal I thought I would never reach."
I did the challenge for my first time in 2009 and I was happy with my results (1:21:51) since I was cycling for 3 months and was overweight. After the first event, I made a goal for the following ...year to lose a lot of weight, get "fit" and shoot for a sub 1hr finish. I trained hard for a whole year and I lost 30 lbs in the process. I was so excited to get under an hour (according to my cycle computer and the ride timer at the summit); I shaved off almost 22 minutes off last year's time. I was relieved and in a world of hurt. I had no idea my accomplishment would inspire family and friends to make positive changes in their lives. Some plan to sign up for the 30th anniversary Mount Diablo Challenge. See you next year!" - Francis Ilao
