The Quicksilver Trail Challenge features a Half Marathon, 10K and 1-mile kids race in the historic mining territory of Almaden Quicksilver County Park in San Jose.
The course scenery is a mix of peaceful oak forest and open meadows and the route is both single-track trails and fire roads with views of the Santa Clara Valley and the Santa Cruz Mountains.
Finishers receive swag bags, finisher medals and awards for finishing in the top three. Proceeds support local charities.
