The course
Courses are 70–80% single-track and 20–30% dirt road, rolling through forest and meadow with views of the Mummy Range, Never Summer Range and Medicine Bow Mountains. Wildlife includes moose, elk, mule deer, black bears and mountain lions.
The 50-Mile tops out just below 11,000' between Middle and North Bald Mountains. Lower sections are more technical; the National Forest trails flow.
Courses are well marked with pink flagging and pin flags, plus flour markings and directional arrows at key intersections; confidence flagging roughly every quarter mile.
