Desert RATS Trail Running Festival is a multi-day trail running event in Fruita, Colorado. The event runs across three days of racing on trails in the high desert, with courses that pass red slickrock cliff buttes, mesas, and sections overlooking the Colorado River. Routes include flowy singletrack and climbs onto mesa terrain.
