About the Ride
The 38th Annual Mt. Diablo Challenge will be held on Sunday, October 4, 2020.

Mt. Diablo is one of the 3 highest peaks in the San Francisco Bay Area climbing 4000 feet with views of the Farallon Islands and the Sierras. The Mt. Diablo Challenge (MDC) is an 11.2-mile, timed bike race that climbs 3249 feet to the summit of Mt. Diablo up South Gate Road. The ride is open to competitive and recreational cyclists - young and old alike. Mt. Diablo State Park is closed to traffic for this event and the first waves can ascend without any descending bike traffic. It's a once a year opportunity to enjoy riding the mountain without cars!

At the top, there is food and drink that is much needed after that epic climb. Then cyclists descend and ride over to Monte Vista High School to pick up their goodies, and celebrate winners in 16 age categories, including King and Queen of the Mountain. There is great food, beverages, vendors and music for a grand celebration!

The Event is held to help benefit Save Mt. Diablo, which helps to preserve the mountain, one of the 3 highest peaks in the San Francisco Bay Area with views of the Farallon Islands and the Sierras.

Preparing for the Ride

There are many local rides up Mt. Diablo during the week and on the weekend. We recommend riding up the Mountain during the week if at all possible to avoid the weekend cars. If you cannot ride during the week, an early morning ride up the mountain can be nice especially on an overcast day because most drive up the mountain for the view. Just remember to stay as far right as safely possible and use pullouts when cars are behind you. When you descend, stay close to the right because many cars try to pass cyclists on blind curves.

Here are some training rides to help prepare you for the Challenge

Event Day

Everyone arrives and checks in for the event early at Monte Vista High School located at Stone Valley Road, Danville, CA. Then cyclists ride over to Athenian School on Mt. Diablo Scenic Blvd. to get ready for their wave. Cyclists are grouped by the time they think it will take to finish the climb.

The first wave starts at 8 am and continue every few minutes. The first waves get to ascend using the whole road. Later waves must stay to the right.

At the top, there is a mini-celebration with food and beverages to replenish after the climb. Then cyclists descend in waves and ride over to Monte Vista High School for a grand celebration with lots of delicious food, drink, music, goodies and awards plus vendors with cool gear! Invite the family to join you there for the festivities!
