From 10 to 12 April 2026, the Desert RATS Trail Running Festival by UTMB will host a multi-distance trail running weekend in Fruita, Colorado. Race options include 10 km, 21 km (half), 50 km, and 100 km, each traversing desert terrain, red rock slickrock, mesa edges, and technical singletrack with varied elevation profiles. The 100 km race is a single loop requiring completion under 20 hours to qualify for the Western States Endurance Run, while the 50 km and 21 km earn UTMB running stones and index credits. Aid stations are plentiful, spaced roughly every 5 miles (or less on longer courses), and participants gather at a lively basecamp festival with race expo, music, and community vibe. As a UTMB World Series event, Desert RATS blends serious trail competition, world-class qualification, and a desert festival atmosphere amidst the striking landscapes of western Colorado.
