Saratoga, United States • 27 Sep 2026
San Jose Trail Challenge : Sanborn County Park
The San Jose Trail Challenge takes place at Sanborn County Park in Saratoga, California, on the eastern slopes of the Santa Cruz Mountains. The park features giant coastal redwood groves and a mix of shaded and open sections. Trails are described as well-groomed but steep and difficult, with flowy singletrack that offers good footing through dense forest. Racers should expect sustained climbs and descents across soft, single-track surfaces.
Available race distances:
- 10K
- Half Marathon (21K)
- 50K
The venue sits at an average altitude of about 420 meters (1400 ft) and average temperatures are listed near 28ºC (82ºF) for the season. Nearby commercial airports include San Jose (SJC) and San Francisco (SFO).
Logistics notes include the absence of onsite parking for racers; participants must park at an offsite location and use a shuttle to reach the venue. Mandatory equipment requirements include a visible bib number and a timing chip for all participants, and a 500 ml water-carrying vessel for 50K entrants. Recommended items include a hydration system or bottle, warm breathable layers, rugged trail shoes, and protective clothing to guard against brush and variable conditions. Trekking poles and short gaiters are permitted or suggested for comfort on steep, technical sections. Visit the organization's website for the most recent information.
