Berkeley Trail Adventure

The Berkeley Trail Adventure offers four trail distances through Tilden Regional Park and Wildcat Canyon in Berkeley, California on September 12, 2026.

  • 10K, 6.0 miles, 1,050 ft elevation gain
  • Half marathon, 13.0 miles, 2,800 ft elevation gain
  • 35K, 21.6 miles, 4,600 ft elevation gain
  • 50K, 31.0 miles, 6,800 ft elevation gain

Most of the routes run on technical dirt trails and non technical fire roads, with about 1.5 miles of asphalt on the 35K and 50K near Inspiration Point. The course includes steep and long hills and offers shaded sections under coast live oak and eucalyptus as well as open sections with views of the bay, the Golden Gate Bridge, and on clear days Mount Tamalpais.

Aid stations appear roughly every 5 to 7 miles and provide a variety of food and drink items such as energy gels and chews, stroop waffles, trail mix, boiled potatoes, soda, sports hydration, and seasonal fruit. Runners are advised to carry their own water because the event is cupless; reusable cups will be available for purchase. Aid stations carry basic first aid items but no anti inflammatory medicine.

The event has a total capacity of 350 entrants. All races are chip timed using disposable chips attached to the backs of bibs. An 8.5 hour time limit applies to the 50K and 35K. Free parking is available at Lake Anza in Tilden Park. Dogs on leash are permitted on course with specific starting placement rules. Volunteers receive a race shirt, food, and event credit. Awards include overall trophies, age group medals, finisher medals, and a pint glass for 50K finishers. Visit the organization's website for the most recent information.
