Become a Member Quicksilver 50K - 50 Mile Run Members Log-in

The 50K and 50 Mile races are run on scenic, hilly trails and fire roads, with 5,440 feet of climb in the 50K and 8,530 feet of climb in the 50 Mile. 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 (and no time cut-offs in the 50K!) 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.

You will run or walk through peaceful oak forests and open meadows, with great views of the Santa Clara Valley and the Santa Cruz Mountains.
