Quicksilver Endurance Runs

21785 Almaden Road

San Jose, CA 25K, 50K, 50 Miler

This Event Took Place Sat. May 11, 2013


All registered runners for the 2020 race (which had to be canceled due to COVID-19) were offered a race credit for the 2021 or 2022 races. They received an email early January 2021 with instructions on how to register for the 2021 race between Jan 10, 2021 and Jan 16, 2021. General registration opened on Jan 17, 2021. We limited capacity as our permit size is not determined yet due to COVID-19. We may select more runners from the waitlist.

50K & 100K description

Great course, great volunteers, great swag, and great post-race BBQ!

Join us for the 37th 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).

Waitlist and refund policy

Given the above, both races will most likely be full. Consider adding your name to the waitlist (your credit card will only be charged if a spot becomes available for you AND you accept that spot).

Runners who need to cancel their registration are eligible for a 50% rollover of their race registration fee prior to 2/7/2021: cancel your registration via your registration history or via the "Edit" link on your receipt. After 2/7/2021, there will be no refund or credit of entry fees for any reason and under any circumstances (unless the coronavirus forces us to cancel again...).


This race would not be possible without the 100+ volunteers who help the runners have a great day on the trails. Please consider volunteering and sign up here:
