Mount Diablo Challenge

East Bay's "Best Uphill Bike Ride"

Sunday, September 25th, 2016

The “Mount Diablo Challenge” is a family-friendly 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. Cycling enthusiasts compete and prizes are awarded for several categories in a ceremony at the Expo Area with food and beverages for all. 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.

Stay & support fellow riders/friends during expanded awards ceremony while enjoying a BBQ lunch by Slow Hand BBQ.
