Cahuilla Rez Ultra

Cahuilla Rez Ultra - October 17, 2026

The event takes place on the Cahuilla Indian Reservation in Anza, California, and raises funds for the tribe's Youth and Family Committee. Multiple race formats use a runnable 2 mile loop on double track dirt road through mountain desert terrain.

Race options include:

• 100 Miler
• 24 hours
• 12 hours
• 6 hours
• Half Marathon
• Tribal Member 5k

The 2 mile loop has about 170 feet of elevation gain per loop and totals approximately 8,500 feet of climb over 100 miles. The half marathon follows reservation roads with roughly 1,500 feet of climb and four aid stations at miles 4.5, 6, 7.5 and 10 offering basic aid. Fixed time races (6/12/24 hour) and the 100 mile race use the same loop. The 100 mile race has a 30 hour cutoff.

An aid station at the softball field will provide hot and cold real food and standard aid station items. There are on-site restrooms that are not portable toilets.

Camping and parking options include tent camping on the softball field, car camping in the adjacent dirt lot, and up to 20 RV spots on a first come, first served basis. Half marathon entrants are not offered overnight camping to preserve space for fixed time participants.

Race awards include shirts, medals on completion, handcrafted top finisher awards, and 100 mile buckles with limited distribution based on signup timing. All net proceeds support the reservation's youth and family programming. Visit the organization's website for the most recent information.
