The best trail running races in the San Francisco/Bay Area geared towards the recreational & casual trail runner.

For more than a decade, Sasquatch Racing has been producing lighthearted, fun, accessible, goofy trail races (or ‘trail parties’ as we often call them) at some of the most beautiful venues in the Bay Area.

All our trail races include a 5K/10K option for those new to the trail as well as a more challenging half marathon distance with plenty of ascent/descent for more seasoned trail runners looking for a challenge. 

No matter what distance you tackle with us, you can count on awesome swag (shirt/race woodallion/custom bib) and a fun post race ‘party’ complete with delicious snacks from Bellwether Farms, Jambar, and others. You can also expect an awesome post race BREWFEST with delicious, chilled brews and a custom, commemorative beer sampler stein!
