Cahuilla Rez Ultra

Cahuilla Rez Ultra takes place on the Cahuilla Indian Reservation in Anza, California. The event offers multiple formats and distances and serves as a fundraiser for the Cahuilla Band of Indians Youth and Family Committee. Registration closes Tue, Oct 13 at 11:59 PM PT.

Distances and formats include:

  • 100 Miler
  • 24 hour fixed time race
  • 12 hour fixed time race
  • 6 hour fixed time race
  • Half Marathon (13 miles)
  • Tribal Member 5k

The primary course for the fixed time events and the 100 mile race is a runnable 2 mile loop on double track dirt road. The loop includes about 170 feet of elevation gain per circuit and the 100 mile course accumulates roughly 8,500 feet of climb with subtle rolling hills. Aid will be available at the softball field with hot foods and typical aid station items, plus non-porta-potty restrooms.

The half marathon follows reservation roads on a roughly 13 mile route with about 1,500 feet of climb and four basic aid stations at miles 4.5, 6, 7.5 and 10. The 100 mile event uses the same loop and has a 30 hour overall cutoff.

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

New for 2026: official results are limited to the mileage completed in the race entered. Runners may not change into a different race during the event. 100 mile finishers receive a buckle. Buckles are allocated to pre September signups and will be mailed if not available on race day. Shirts, medals, and handcrafted awards are provided according to event rules; 5k participants do not receive a shirt but do receive a buckle.
