Cahuilla Rez Ultra

Event Details

The Cahuilla Rez Ultra takes place on October 17, 2026, on the Cahuilla Indian Reservation in Anza, California. The event is a fundraiser for the tribe's Youth and Family Committee, which supports youth programming throughout the year.

Distances

The event offers several distances:

• 100 Miler
• 24hrs
• 12hrs
• 6hrs
• Half Marathon (13.1 miles)
• Tribal Member 5k

Course Information

The 100 Miler, 24hr, 12hr, and 6hr events take place on a runnable 2-mile loop of double-track dirt road. Each loop has about 170 feet of elevation gain. The total elevation gain over 100 miles is approximately 8,500 feet. The Half Marathon course covers 13 miles of reservation roads with about 1,500 feet of climb.

Aid and Facilities

There is an aid station at the Softball Field providing hot and real food, including items like burgers, pizza, and quesadillas. The Half Marathon has four basic aid stations with water and fruit. The event features real, non-portable bathrooms.

Logistics and Rules

Camping is available on the softball field or in an adjacent dirt parking lot. RV parking is allowed for up to 20 vehicles on a first-come basis. The Cahuilla Casino Hotel is located about 3 to 5 miles from the race site. A key rule for 2026 is that no mid-race changes between distances (e.g., from 24hr to 100 Miler) are allowed. Finishers in the 100 Miler receive a buckle if they registered before September. All participants receive a race shirt and a medal upon finishing.
