Organized by Troy’s California Trail Runs, the Fall edition uses the historic Almaden Quicksilver trails and old mining roads to deliver a challenging, scenic day of trail running for all abilities. Courses combine roughly 60% dirt roads and 40% single-track, with sustained climbs, technical sections and sweeping valley views—expect a proper hill workout rather than a casual jog. Distances range from a short 5K up to a 50K ultramarathon, with staggered starts and course maps/GPX available from the race page. Check the official event page and the UltraSignup listing for exact start times, parking/aid info and registration details.
