Embark on an unforgettable ultra-running journey at the Ultra Cheii 100 Mile (Solo & Relay) in Tijeras, New Mexico, on May 23, 2026. This challenging endurance event, set amidst the scenic piñon and mesquite forests just east of Albuquerque, features a unique 1.05-mile loop course, ensuring unparalleled logistical support for both 100-mile soloists and relay teams. Runners will navigate 97 loops of 100% singletrack trail, gaining approximately 180 feet of elevation per circuit for a total vertical gain of around 17,000 feet over the 100 miles. Typical race day conditions in late May in Tijeras, NM, present a challenging mix, with average highs around 83°F and lows around 54°F. Runners can expect sunny and clear skies, with the 7,200-7,500 foot elevation bringing warm days and cool nights, and a minimal 1% chance of precipitation.

The Ultra Cheii is renowned for its vibrant "basecamp" experience, transforming the start/finish area into a 40-hour celebration complete with hot and cold food, music, heaters, and dedicated volunteers. With two aid stations strategically placed on each loop, including the main basecamp and a water-only and drop bag pavilion, runners have constant access to essential supplies, allowing for lighter running and maximum effort. Free camping and parking at the private land race venue further enhance the community atmosphere, making it a true Memorial Day weekend party for runners and crew alike. Pacers are welcome to join soloists from sunset, adding another layer of support as the solar-lit course becomes truly magical under the night sky.

What truly sets Ultra Cheii apart is its inclusive, runner-first approach, offering a generous 40-hour cutoff and no mid-race cutoffs to help participants achieve their goals. Adding a touch of local charm, the race embraces the "Legend of the Cheii," referencing the native horned lizards of New Mexico, considered the "grandfather of the earth," a unique cultural element that connects runners to the land. Whether tackling the full 100 miles solo or sharing the challenge with a relay team, the Ultra Cheii promises a well-supported, festive, and deeply memorable trail running adventure.
