A fierce high-altitude mountain challenge through Coahuila's backcountry
A demanding 83-kilometer mountain ultra through the Sierra de Arteaga's rugged terrain, gaining nearly 3,800 meters of elevation on a course that traverses forest, mountain ridges, and high-altitude landscapes. An 18-hour cutoff and a pre-dawn 4:00 AM start give runners sufficient time to experience both the night and day faces of Coahuila's most dramatic mountain range.
