The Sheep Mountain 50 throws everything it has at runners, challenging you from start to finish, among the mountains and hills lining the western slope of the South Park Valley. Runners looking for a wilderness experience, stunning views, opportunities for technical terrain mixed with remote forest service roads… will fall in love with this course. The third race of our Fairplay Series of runs, The Sheep Mountain 50 promises to provide runners with an unforgettable experience that celebrates the history, and rough and tumble nature, of this mountain region. NEW IN 2018! We’ve added a 50k option to this weekend of high mountain running. Join us for a challenging 50k in the thin mountain air of Fairplay. Run 32.25 miles of some of the more challenging miles of the 50 mile course. BE ADVISED: This race has been described as “Beautifully Difficult.” While the course meanders through some amazing country with stunning views of the Mosquito Range and surrounding 14er peaks, it is tough. The course features a terrain type for every runner, and a fair amount of what some would consider “unrunable stretches.” The average elevation for the course (10,662′) is bested only by the San Juan Solstice 50 in Lake City. Some of the aid stations are in remote locations that are difficult for even our volunteers to get to. While many runners have joined us for their first 50-mile here (and succeeded), it is only recommended for the truly stubborn and determined. Middle-of-the-pack typically finishes between 13 and 15 hours. You have been advised, save the whining. Distance: 51 Miles | 50k, Elevation Gain/Loss: 9,600’/9,700’ | 6,200’/6,200′, Average Elevation: 10,700′ | 10,500′, Start Time: 6:00 AM (Both Races), Time Limit: 16 Hours (Both Races)
