Sanborn Trail Challenge
The Sanborn Trail Challenge takes place on Saturday, March 1, 2025 at Sanborn County Park in Saratoga, California. The event offers multiple race distances on park trails and has an overall 4.5 hour time limit for the half marathon.
- Kids Run
- 1 Mile
- 4 Mile
- 8 Mile
- Half Marathon
The course is composed of about 95% single track. Trails are steep and technical, running through a mixed evergreen forest with Redwood, Douglas Fir, Oak, Madrone, and Tanbark Oak. Most trails are shaded and wooded.
Elevation gain is substantial on the longer routes, for example the 4 Mile route has about 1,315 ft ascent, the 8 Mile about 2,634 ft ascent, and the Half Marathon about 4,528 ft ascent. Shorter routes list smaller ascents.
Aid and facilities are concentrated at the Peterson Grove Picnic Area start/finish, which also serves as a full aid station. Full aid is available at mile 4 for longer races and additionally at miles 8 and 12 for the half marathon. One portable toilet is provided at the start/finish; additional full service restrooms are a few hundred yards away at the Costanoan Group Picnic Area. Courses are marked with ribbons, signs, and gypsum; yellow ribbons mark a sharp turn between Sanborn Trail and Peterson Trail. Drop bag service is not available.
Online and race day registration are offered. Entry fees are non refundable but may be transferred to future Troy’s California Trail Runs under the event transfer policy. Parking requires self registration and carries a $6 per vehicle fee. Volunteers help at aid stations and receive credit toward a future race.
