Join us for a Half Marathon, 10K and 5K offering spectacular 360 degree views of the Bay Area!

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: 8:00am
10K: 8:15am
5K: 8:45am

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 5/01, so we recommend early registration.


Want to run with us, but can't make it in person?
