Northern Mexico's most extreme mountain ultra
A grueling 163-kilometer journey through the Sierra de Arteaga's wild high-altitude terrain, accumulating an extraordinary 9,480 meters of climbing across two days and nights. Starting at 4:00 AM on Saturday, runners navigate forest roads, mountain trails, and dramatic ridgelines at elevations between 2,584 and 3,480 meters — spending much of the race above 8,500 feet in one of the most spectacular and remote mountain ranges in northern Mexico.
