Event overview
Ultra Cheii 100 Mile takes place near Tijeras, New Mexico. Distances offered:
- 100 mile solo
- 100 mile relay
The event is held on private land bordering national forest and includes free camping and free parking. Basecamp is staffed overnight with hot and cold food, music, heaters, and volunteers. There is a 40-hour time limit to complete the 100-mile distance; runners who do not finish within that limit are recorded as a DNF. There are no mid-race cutoffs.
Course and rules
The course is a 1.05 mile loop on 100% singletrack through piñon and mesquite. Each loop has about 180 feet of elevation gain. The 100-mile distance equals 97 loops. Solar lights are placed along the loop, and a headlamp is still recommended. The average elevation is about 7,200 feet and typical temperatures at this time of year are around 60-70 degrees.
There are two bathrooms and two aid locations on the loop: basecamp (main aid) and a water-only and drop bag pavilion halfway through. Drop bags are allowed at both covered locations. Solo runners may have a pacer starting at sunset after checking in and obtaining a pacer bib; relay teams may not use pacers. Relay teams may have 2-4 runners, must run the final loop together, and share other specific team rules. Solo finishers receive a buckle; relay finishers receive a finisher award. All finishers receive sunglasses, a buff, and a race t-shirt. Visit the organization's website for the most recent information.
