The Zanja Peak Endurance Challenge is a trail running and hiking event in Yucaipa, CA on November 14, 2026, organized by Yucaipa Adventure Company. The event is listed as postponed. It uses terrain in the Crafton Hills and offers multiple course distances that vary in length and elevation.

The full 21 mile route begins and ends at the Crafton Hills College track and includes three fully stocked aid stations. The course description notes sustained climbs, technical descents, and ridgeline views within the Crafton Hills. The 10 mile course is described as a middle distance with challenging climbs, faster sections, and a well-marked route with full support. The 4 mile course is shorter with punchy climbs and is presented as an introduction to trail running.
A portion of registration revenue supports local conservation: 10% of all registration fees will be donated to the Crafton Hills Open Space Conservancy, which focuses on trail stewardship, habitat protection, and open space preservation in the Crafton Hills.
