About the race
The Glorieta Twelve Hour Endurance Race is a destination trail event near the southern terminus of the Sangre de Cristo Mountains, held in Santa Fe, NM on May 1, 2027. Participants have 12 hours to complete as many 3.2-mile trail loops as they wish.
The event offers a fully stocked aid station, a covered area for storing gear, and on-site activities for family and friends who attend to support participants. The course is organized as repeated trail loops, allowing runners to stop or continue between laps according to their plan.
The format accommodates athletes attempting an ultra-distance effort and experienced trail or ultra runners who want a structured, time-based challenge. Support services and the looped layout aim to make logistics straightforward for those focusing on distance, pacing, and time on course.
