The 2023 Quicksilver 100K AND 50K Endurance Runs will be held on Saturday, May 13, 2023.

Great course, great volunteers, great swag, and great post-race BBQ! (well that last one was true before Covid)

Join us for the 38th edition of the Quicksilver Endurance Runs. The 50K and 100K races are run on scenic, hilly single track 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. Run for a good cause: 50% of the race proceeds go to non-profits that help kids stay healthy or fund trail advocacy projects.

Both Races will start at the Hacienda Entrance of the Almaden Quicksilver County Park (21785 Almaden Road, San Jose, CA 95120).
