Race Information
Just across the East Bay hills from San Francisco, Mt. Diablo beckons! Come stomp to the peak at just under 4000 feet. Choose from a wild range of race distances: 5k, 10k, Half Marathon and 30k are all on tap.
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.
Age group awards will be awarded to the top 3 finishers in 5 year categories (smaller categories for the younger ages).
