About This Race
Devil on the Divide stands among Colorado's most demanding and scenic trail races, combining high-altitude challenge with Continental Divide vistas in Clear Creek County. The race takes runners through remote mountain terrain with summit elevations exceeding 13,000 feet, making it as much a test of altitude adaptation as running fitness. The point-to-point courses feature 100% dirt surfaces, predominantly single track, winding through some of Colorado's most pristine and challenging backcountry. This race demands respect and preparation. The 50K requires prior ultra experience, while the 22K strongly recommends high-altitude trail running background. Race directors enforce strict cutoff times and verify experience levels, understanding that the remote, technical terrain leaves little room for error. The combination of altitude, distance, and technical terrain creates a genuinely challenging mountain running experience.
Both distances follow point-to-point routes through Clear Creek County's high country, starting in Empire, Colorado. The courses consist entirely of dirt surfaces with the majority being technical single track trail. The 50K reaches elevations over 13,000 feet with 6,500 feet of climbing, while the 22K involves 3,400 feet of elevation gain. The remote, mountainous terrain requires confident navigation skills and mountain running experience.
