Event overview
The Fleet Feet Fall Classic - Trail takes place on October 18, 2026 in Chico, CA at Upper Bidwell Park (South Rim Trail Head / backside of Bidwell Golf Course). The event includes two trail races:
- Half marathon
- 4-mile endurance challenge
Both races start on the south side of Upper Bidwell Park on Annie’s Trail and follow single-track trails. The half marathon features a significant climb with about 1600 ft of gain in the first half, an aid station at the top of 10-Mile House, and a mostly downhill second half that finishes through Yahi and the golf course. The course includes a creek crossing and mixed trail and fire road sections.
Format, services and logistics
The 4-mile endurance event is run as a repeating 4-mile loop. Runners who finish a loop in under 60 minutes may start the next loop; direction changes every other lap. Rounds continue hourly for up to eight hours, and completing eight loops equals roughly 32 miles. The endurance winner is determined either by last person standing or the first to cross the line in a final-hour foot race; top finishers receive awards.
Aid stations and restrooms: three for the half marathon and two for the 4-mile race, including the Start/Finish and Bear Hole locations offering water, electrolytes and nutrition. Packet pickup, registration deadlines, guaranteed tee-shirt cutoff, parking options, bike valet, sweat check, and awards are provided as described by the organizer. Portions of race proceeds support Chico Velo Trailworks and local fire academy cadets. Visit the organization's website for the most recent information.
