Diablo Trail Run
Sunday, September 6, 2026
Clayton, California
The Experience
Mount Diablo provides spectacular views of the San Francisco Bay Area and surrounding valleys. The 4 mile course is relatively flat and fast within Mitchell Canyon. The longer events are mountainous and very scenic.
(Distances are accurately measured using a Rolatape® surveyor's measuring wheel.)
