The Quicksilver Trail Challenge includes 3 races: a Half Marathon, a 10k, and a one mile free 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. All entrants will receive a swag bag, all finishers will receive a commemorative medal, and the top three overall and top in each age group will receive a prize as well. Proceeds from this event will again be donated to local charities. The one mile kids race will be free. Visit the Quicksilver Trail Challenge event page for complete details.
