Cahuilla Rez Ultra 2026

Cahuilla Rez Ultra offers multiple trail and road running distances on the Cahuilla Indian Reservation in Anza, California. Options include a Tribal Member 5k and half marathon, plus 6-hour, 12-hour, 24-hour, and 100-mile formats. This event takes place in a mountain desert environment and benefits the Cahuilla Band of Indians, with all proceeds after operational costs directed to the tribe's Youth and Family Committee. The race incorporates cultural and educational components about the Cahuilla people, connecting the event directly to the reservation. The primary ultra course is a 2-mile loop on a double-track dirt road, with approximately 170 feet of elevation gain per lap, totaling around 8,500 feet over 100 miles. The half marathon course covers 13 miles on reservation roads, featuring about 1,500 feet of climb and four aid stations. A main aid station at the softball field provides hot and substantial food choices, along with access to permanent restroom facilities. Camping and crew support are available for longer races, including tent camping on the softball field, car camping in a nearby dirt lot, and limited free RV spots. Participants completing 100 miles receive a buckle, all finishers get a medal, top finishers are awarded handcrafted prizes, and the Tribal Member 5k offers a buckle instead of a shirt.
