Quicksilver Trail Challenge 

1/2 Marathon, 10K, & Kids Run - Oct 19th 2013

Join us for the 2013 Quicksilver Challenge race!


Hosted by the Quicksilver Running Club for many years, the Quicksilver Challenge offers some shorter, yet challenging race distances in Almaden Quicksilver County Park.  The Quicksilver Challenge includes three races: a 10K, a Half Marathon, and a one mile Kids Race run on single track trails and fire roads. You will see parts of the park and the quicksilver mines while running 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 challenging, the friendly aid stations and beautiful scenery make the Quiksilver Challenge an excellent choice for both novice and experienced trail runners.


Be sure to check out this challenging race, in addition to reading all the information below.  Take a look at                          to get a feel for typical times to finish the race.


Volunteers Needed

Volunteers are always needed on race day to help out at the aid stations and at the start/finish area. There are a variety of jobs and hours are flexible. Volunteering is a lot of fun and greatly appreciated by the runners.  If you or someone you know is interested,  just email me.

Please contact me if you have any questions

Have a good training, be safe, and see you on race day!​​
