2026 San Jose Trail Challenge

The event is scheduled for Sep 27, 2026 at Sanborn County Park near West Valley College in Saratoga, California. It is the third edition of the San Jose Trail Challenge and includes options for participants and for spectators.

Sanborn County Park sits on the eastern slopes of the Santa Cruz Mountains and contains giant coastal redwood groves. Trails in the park are described as well groomed but steep and difficult, and the forested setting is shaded and relatively temperate compared with surrounding lowlands. The course runs on flowy singletrack through dense forest, offering pronounced climbs and descents with generally good footing.

The event offers multiple distance options:

  • Trail 50K
  • Trail Half Marathon (21K)
  • Trail 10K
  • Spectators

Race day information includes arrival and heat details, volunteer opportunities, and a runners guide. The description notes nearby parking at West Valley College Parking Lot 5. The terrain and forest cover are emphasized as defining features of the event experience. Visit the organization's website for the most recent information.
