Half Marathon

Half Marathon Course: The course takes place almost entirely on remote dirt roads. It is a single loop course beginning at approximately 8,700 ft. and traveling above 9,500 ft. Climbs and descents are fairly mellow for a mountain race, but we promise it will be challenging. 4 aid stations will be on course complete with water, sports drink, and fruit. The race is chip timed. Half Marathon Pricing: $70/runner before April 1 $80/runner before July $85/runner up to race day
