Special this year - 30th edition! - Sign up early
Our 3 races are run on scenic, hilly trails and fire roads. You will run through peaceful oak forests, wide open meadows, and along ridges with spectacular views of the Santa Clara Valley and the Santa Cruz Mountains. Although the course is very challenging, the friendly aid stations and beautiful scenery make Quicksilver an excellent choice for a first trail ultra-marathon. And the outstanding post-race barbecue is a fitting reward after you’ve met the challenge.
Runners who sign up after 4/10 are not guaranteed the nice goodies. We will fill up again this year so sign up today.
