Cahuilla Rez Ultra : Anza, California

Cahuilla Rez Ultra is a multi-distance running event held on the Cahuilla Indian Reservation in Anza, California. The event raises funds for the Cahuilla Band of Indians, with 100% of funds not used for race operations directed to the tribe's Youth and Family Committee. The event includes cultural and educational elements about the Cahuilla people and takes place in a mountain desert environment.

Distances and formats include:

• 100 Miler
• 24hr
• 12hr

The main course is a runnable 2 mile loop on double-track dirt road with about 170 feet of elevation gain per loop and roughly 8,500 feet of total climb over 100 miles. The half marathon follows reservation roads for 13 miles with about 1,500 feet of climb and four basic aid stations at miles 4.5, 6, 7.5, and 10. The central aid station at the softball field offers hot and real-food options and there are non-porta-potty restroom facilities.

Camping and crew support are available on site. RV parking is free but limited to 20 spots on a first-come, first-served basis. Tent camping is 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.
