Zanja Peak Endurance Challenge

The Zanja Peak Endurance Challenge returns to Yucaipa, California on November 14th, offering runners and hikers a rugged and unforgettable experience through the Crafton Hills' breathtaking terrain. This endurance event features three distinct distances catering to different levels of expertise: the challenging 21 Mile Endurance Challenge with over 4300 feet of elevation gain, the more moderate but equally scenic 10 Mile Trail Challenge featuring around 1600 feet of ascent, and a beginner-friendly yet still demanding 4 Mile Trail Experience that adds about 600 feet in vertical. Participants gather at Crafton Hills College Track for both start and finish lines.
Race morning will see Yucaipa's trails alive with runners and hikers as they prepare to tackle the varied terrain laid out by the Zanja Peak Endurance Challenge organizers. The atmosphere is one of camaraderie, respect for nature, and a shared sense of adventure. Runners can expect firm yet slightly soft trail conditions that are both challenging and rewarding underfoot.
Since its inception, this event has become an integral part of Yucaipa’s endurance community calendar. Over the years, it has attracted hundreds of participants annually who come to test their limits on some of Southern California's most pristine trails. A portion of each participant's registration fee—10% in total—is donated directly to the Crafton Hills Open Space Conservancy (CHOSC), supporting critical conservation efforts and trail stewardship that protect these landscapes for future generations.
The course weaves through the rugged beauty of the Crafton Hills, offering sustained ascents and technical descents along with panoramic views at every turn. Runners will encounter three fully stocked aid stations positioned strategically throughout the route to provide necessary hydration and nutrition as they traverse this challenging terrain. The 21 Mile Endurance Challenge is designed for those seeking a true test of endurance, pacing, and grit, while the 10 Mile Trail Challenge captures the spirit of Zanja Peak with its mix of climbs and fast sections, all framed by stunning ridgeline views.
Race morning temperatures in Yucaipa typically range between mild lows to comfortable highs, making it an ideal day for outdoor activity. UV index is expected to be low at around 2.0, ensuring that participants can enjoy the race without excessive sun exposure concerns. Trail conditions are firm and slightly soft, offering a balanced challenge underfoot.
