Embark on an unforgettable ultra-running experience at the Cahuilla Rez Ultra, set for October 17, 2026, in Anza, CA. This unique event, hosted on the scenic Cahuilla Indian Reservation, offers distances for every ambitious runner: a challenging 100-mile race, 24-hour, 12-hour, and 6-hour timed events, and a Half Marathon. The course for the fixed-time races and the 100-miler features a runnable 2-mile double-track dirt road loop, presenting rolling hills with approximately 170 feet of elevation gain per loop, accumulating to around 8,500 feet over 100 miles. The Half Marathon takes runners on a 13-mile tour of reservation roads, also on double-track dirt, with about 1,500 feet of climb. Typical race day conditions in October feature pleasant highs around 83°F and lows near 56°F, with minimal chance of precipitation, providing an ideal climate to push your limits.

What truly sets the Cahuilla Rez Ultra apart is the opportunity to run on sovereign tribal lands, offering a culturally enriching experience amidst the beautiful mountain desert landscape. This event is a vital fundraiser, with proceeds benefiting the Cahuilla Band of Indians Youth and Family Committee, supporting their year-round programming. Runners consistently praise the serene atmosphere, particularly the star-filled night skies that illuminate the course for overnight competitors. The main hub at the softball field provides exceptional support, featuring a generously stocked aid station with hot and prepared foods like burgers, pizza, and spaghetti, along with proper bathrooms. Half Marathon participants will find additional aid stations along their route.
