Oakland Hills Trail Run

Oakland Hills Trail Run takes place in Redwood Regional Park, Oakland, CA, offering 35K, Half Marathon, and 10K distances. Runners traverse a forest of coast redwoods and other park communities, with most of the course on technical dirt trails and non-technical fire roads. Elevation gains are substantial: about 4,550 feet for the 35K, 2,900 feet for the Half, and 1,250 feet for the 10K.

Trekking poles are permitted. The event is cupless, so runners must carry their own water, with aid stations providing gels, snacks, fruit, and drinks. All races are chip-timed, and the field is capped at roughly 330 entrants.
