The 50K and 100k 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 the Quicksilver 50k an excellent choice for a first trail ultra-marathon. The outstanding post-race barbecue is a fitting reward after you’ve met the challenge.


We are always looking for race volunteers, so if you or someone you know may be willing to help out, please fill out our online volunteer form.  The race would not be possible without the wonderful help from our volunteers!


Quicksilver Running Club strives to be one of the “best runs for your buck”. We are a 100% volunteer, nonprofit organization. There are a lot of hours and no one gets paid. You can feel good as part of the proceeds go to charities and good causes. For example we fund schools to help them get sports equipments and foundations to keep parks open and create more trails.​
