*RACE DATE FOR 2015 = MAY 9*

2,430 acres of land extending north from Tilden Park, Wildcat Canyon Regional Park is normally inaccessible to trail runs due to a lack of staging area. Thanks to a generous concession by the East Bay Waldorf School (which sits next to a trailhead), however, we are finally able to make these incredible trails available for a run you won't soon forget! Views of San Francisco, the Golden Gate Bridge, Alcatraz, Mount Tamalpais, the Bay and even the ocean await you.

Trails are primarily fire trails with a few very short sections of paved trail (less than 10%).

All runners will receive custom finisher medals and custom shirts (cotton and tech shirts available). More info on our shirts/awards page.

Age group awards will be awarded to the top 3 finishers in 5 year categories (less for the younger ages).

Hikers/walkers welcome!


Half Marathon: 8:00
10K: 8:15
5K: 8:45

Half Marathon cut-off is 12:30pm.

All races will be professionally chip-timed.

Participation will be limited and shirt sizes (and tech shirts) can only be guaranteed to those who sign up by 4/27, so we recommend early registration.
