About This Race
The Chihuahua by UTMB 94K carries runners deep into Mexico's Copper Canyon region, a vast network of gorges in the Sierra Madre Occidental that rivals the Grand Canyon in scale. As part of the UTMB World Series, this race brings the international ultra-running circuit to Chihuahua state, where the course traverses indigenous Tarahumara lands through one of North America's most striking canyon systems. The 94-kilometer distance positions itself as the event's serious ultra offering, designed for experienced distance runners ready for extended time on technical terrain. The route moves through multiple ecological zones, from high pine forests to the warmer canyon floors, demanding careful navigation of rocky trails and sustained attention to pacing. This is desert mountain running at altitude, where heat management and hydration planning become as critical as physical preparation. For runners seeking qualification points for UTMB Mont Blanc or simply wanting to experience Mexico's legendary trail running terrain, the 94K provides a substantial test without the multi-day commitment of longer ultra distances. The region's cultural significance—home to the Rarámuri people renowned for their long-distance running traditions—adds depth to the physical challenge.
The course explores the Copper Canyon system through a mix of mining roads, indigenous footpaths, and technical singletrack. Runners move between ecological zones as the route descends into canyon sections and climbs back to forested ridgelines, with terrain ranging from smooth pine-needle trails to rocky, technical passages requiring careful foot placement. Water and aid station spacing reflects the remote nature of the region.
