Join in the adventure and support Save Mount Diablo!

Save Mount Diablo is teaming up with Brazen Racing for this year's Diablo Trail Adventure. Races will include a Half Marathon, 10K, 5K and Family Hike.

For over 39 years Save Mount Diablo has worked tirelessly to preserve and increase the open space on and around Mount Diablo. In that time, their efforts have taken us from 6,788 acres of open space to over 100,000 acres of open space on and around the mountain! A portion of all entry fees will go to Save Mount Diablo to help them continue preserving open space and trails for all of us to enjoy.

All courses are on trails. While there are some hills, this event, like all Brazen Racing runs, is very friendly to first-time trail runners and experienced runners alike. Depending on the weather, all distances may include mud and creek crossings!

Walkers/hikers are welcome in all distances. Photos of our recent events can be seen here.

Age group awards will be awarded to the top 3 finishers in 5 year categories (smaller categories for the younger ages).

Start times will be: 9:00am for the Half Marathon, 9:10am for the 10K and 9:20am for the 5K. The Family Hikes will begin at 9:45am.
