Berkeley Trail Adventure

The Berkeley Trail Adventure takes place in Tilden Regional Park, offering participants the opportunity to run through the natural landscapes of the East Bay. The course features a mix of shaded sections lined with coast live oak and eucalyptus trees, as well as open, exposed trails. On clear days, runners can see views of the San Francisco Bay, the Golden Gate Bridge, and Mt. Tamalpais.

The event offers four distinct distances:

  • 50 km (8.5-hour time limit)
  • 35 km
  • Half Marathon
  • 10 km

The race follows a cupless policy to reduce waste on the trails. Participants are responsible for carrying their own water bottles or reusable containers, as paper cups are not provided at aid stations. Stocked aid stations are positioned every 5 to 7 miles and offer a variety of snacks such as fruit, cookies, pretzels, and electrolyte drinks.

Free parking is available at Lake Anza within Tilden Park. Participants who finish their respective distances receive a custom medal, while those completing the 50 km also receive a pint glass. Custom trophies are awarded to the top three male and female finishers in each distance, and age-group medals are provided across several categories.

Registration for the event includes a performance tri-blend shirt, provided the participant registers by the specified deadline in late August. Visit the organization's website for the most recent information.
