Crafton Hills Endurance Run — 21 Miles of Grit, Climb, and Community
Welcome to the Crafton Hills Endurance Run, a true testpiece of Southern California trail running where strength meets strategy and every climb tells a story. Starting and finishing on the Crafton Hills College track, this 21-mile adventure launches runners straight from the track into the rugged hills above Yucaipa for a day of relentless elevation, sweeping views, and unforgettable terrain. With 4,370 feet of vertical gain, this course is built for athletes who crave challenge — sustained climbs, fast descents, and the kind of terrain that rewards patience as much as power. Whether you’re chasing a new personal benchmark or simply looking to push your limits on home soil, this is a course that demands respect and delivers pride at the finish line.
Runners will be supported by three fully stocked aid stations positioned throughout the course — each staffed with experienced volunteers ready to keep you fueled, hydrated, and moving strong. From electrolytes and real food to high-energy encouragement, you’ll never feel alone out on the hills.
And this race is about more than miles and elevation — it’s about protecting the trails we love. 10% of all registration fees will be donated directly to the Crafton Hills Open Space Conservancy, helping support conservation efforts, trail stewardship, and the long-term preservation of these incredible local landscapes for future generations of runners and outdoor enthusiasts.

Endure the hills.
