The Quicksilver Challenge includes 3 races: a 10K, a Half Marathon, and a one mile Kids Race, run on scenic, single track trails and fire roads in the historic Quicksilver mining territory of Almaden Quicksilver County Park. Travel through peaceful oak forests and open meadows, with great views of the Santa Clara Valley and the Santa Cruz Mountains. Although the course is very challenging, the beautiful scenery will make the miles go by quickly. If you’ve only run roads before, the Quicksilver Challenge is a wonderful introduction to trail running.
Online registration has closed but we will be offering same-day registration the morning of the race from 7am.
- 10K: $40
- Half Marathon: $55
The one mile kids race is free and kids can sign up on race day morning.
