Cahuilla Rez Ultra
Anza, United States • 18 Oct 2025
Set on the Cahuilla Indian Reservation in Anza, California, Cahuilla Rez Ultra is a Native‑organized fundraiser for the tribe’s Youth and Family Programming. Runners can choose from a 100‑mile option, 24, 12, and 6‑hour races, a half marathon, and a Tribal Member 5k. The course is a scenic 2‑mile loop on double‑track dirt roads, with about 128 feet of elevation per loop and roughly 6,400 feet of total gain for the 100‑mile distance.
The half marathon is a 13‑mile tour of the reservation. The 24‑hour race offers a star‑filled night with camping. Four aid stations provide essentials; campers may stay at the softball field, with limited RV spots. Visit the organization's website for the most recent information.
