About Ultra Cheii Relay (& Solo)

The Jemez Mountain 40 in New Mexico offers 100-mile relay and solo, 50-mile solo, and kids' races on a 1-mile loop course with 160 feet of gain per loop. Pacers are allowed starting at sunset (about 8pm). Pacers MUST get a pacer bib and check-in with staff (including sign a waiver) at our registration table, which can be done at bib pickup or at any point during the event. For safety, no one is allowed on course who has not signed in with us.
