Please, join us for the 2015 Quicksilver Trail Challenge race!


Hosted by the Quicksilver Running Club for many years, the Quicksilver Trail Challenge offers some shorter, yet challenging race distances in Almaden Quicksilver County Park.  The event 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 Quicksilver Trail 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 past results to get a feel for typical race finishing times.

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.  Please, contact the Race Director if you are interested in helping out.

Where does your money go?

The Quicksilver Running Club strives to be one of the “best runs for your buck.” We are a 100% volunteer, non profit organization.  Over the years the Quicksilver Running Club has contributed over $100,000 to various charities. The 2014 Quicksilver Challenge will benefit AchieveKids Schools, located in East Palo Alto and San Jose.


Check-in and Start Time Information:


Races start at 8:00am for the 10K and Half Marathon, and 9:00am for the Kids Race.  Kids do not need to register in advance.


All Runners MUST check-in on race day. Bib numbers and goodie bags may be picked up between 6:45 and 7:45am on race day at the located at the Mockingbird Parking Lot.​  You can look up directions to the race start.


The parking lot at Mockingbird can fill early on race day. THERE IS NO PARKING ON THE STREET ADJACENT TO THE MOCKINGBIRD PARKING LOT. Once the lot is full, cars will be directed to park on residential streets about 1/4 mile from the start area. It is about a 5-minute walk to the starting area from the residential parking area, so allow plenty of time in case you don’t get into the lot.


Course Information and Aid Stations:



Weather and Hazards:

Normal starting temperatures are 45-60F; afternoon temperatures can be anywhere from the 60-90F.  YOU SHOULD CARRY AT LEAST ONE WATER BOTTLE — the weather is often warm and it can be a long time between aid stations if you are moving slowly and are out of water. While the temps are normally moderate, it can feel very warm when it gets into the mid-70s due to trail exposure. Rain is possible, though not likely. Although we work very hard to keep the trail free of poison oak and tall grass, there is poison oak along the course. Be on the alert for rattlesnakes and ticks.




Race Rules:

  1. Race numbers must be worn on the front so they are visible to checkpoint personnel.

  2. Race numbers cannot be transferred to another runner.

  3. No pacers are allowed.

  4. The following aid station cut offs will be applied for the 10K and the Half Marathon:

    • Prospect #3 (2nd pass through) - 10:25 am

    • Randol/Isabel - 11:00 am

    • English Camp - 12:00 pm

    • Finish Line - 12:30 pm

  5. No ties will be allowed for awards.

  6. There will be no drop bags, given the race distances.

  7. If you DROP GO TO THE SCORING TABLE AT THE FINISH LINE to let us know you have dropped.  It is your responsibility to let us know at the finish line that you have dropped. If we call search and rescue because we don’t know where you are, you will likely get a very large bill from the County for the search.


Please contact the Race Director if you have any questions about the event.

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