Mt. Diablo Challenge – 511 Contra Costa

Mt. Diablo Challenge

Traditionally, the Mount Diablo Challenge is a 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‚Äôs land conservation efforts.
