Trailquake

Trailquake 2026 is Brazen Racing’s trail event at Sanborn Park, 16055 Sanborn Rd., Saratoga, CA. It offers 5K, 10K, and half-marathon distances. Runners traverse redwoods and pines on spectacular single-track trails, with ascents to peaks that reward you with panoramic views.

The course suits all levels: experienced runners can push on the hills; newcomers can walk the climbs and conserve energy for flats and downhills. The atmosphere is playful and welcoming—watch for banana slugs along the way and feel the “Richter scale” return to the San Andreas Trail. Finishers can receive shirts or upgrade options; remote runner participation is available. Visit the organization's website for the most recent information.
