Two big climbs before mile 15, then a boulder field
The course front-loads real difficulty: a 2,500-foot ascent followed by a 1,700-foot descent, then another 1,200-foot climb, all within the first 15 miles. Highly technical, rocky singletrack sections occur from mile 7-11 and mile 16-18, and the Dolly Sods section adds an exciting boulder-hopping stretch from mile 30-31. This is not a course that eases you in.
