Course description
A loop of 4WD roads, dirt trails, and cross-country travel through Colorado’s San Juan Range, crossing thirteen major passes in the 12,000–13,000 foot range. The course links Silverton, Telluride, Ouray, and Sherman — the most remote town in the contiguous United States — and tops out at the 14,048-foot summit of Handies Peak. The race alternates direction every year; clockwise is generally described as “up the ramps and down the walls,” favoring longer, steadier climbs and shorter, steeper descents.
Elevation change
33,441 feet of climbing and 33,441 feet of descent (66,882 feet total change), averaging 11,186 feet of elevation across the course. Low point 7,680 feet (Ouray); high point 14,048 feet (Handies Peak summit).
Aid stations
Key stations include Cunningham (mile 9.3), Maggie Gulch, Sherman, Grouse Gulch (crew access, drop bags), Ouray (crew access, the course’s low point), Kroger’s Canteen — a tented aid station at 13,100 feet on Virginius Pass, famous for hand-cooked pierogis — Telluride and Animas Forks (part of the “Big 4” aid stations with the widest food and service options), and Chapman Gulch (foot access only, drop bags accepted).
Special conditions & average temps
Afternoon temperatures at low points like Ouray can hit the mid-80s°F, which feels considerably hotter at altitude, while high passes can still hold snow in mid-July, with runners postholing near Virginius Pass in some years. Nighttime temperatures at 12,000+ feet drop well below freezing. Afternoon thunderstorms with lightning are a real risk on the exposed passes. Altitude alone is a major factor — most of the course sits above 11,000 feet, and the high point at Handies Peak is above 14,000 feet.

Registration deadline & how to get in
Lottery only, via hardrock100.com, typically opens in the fall for the following summer’s race, with the drawing held in early December. To even enter the lottery, applicants must have completed one of roughly 30 approved mountainous 100-mile-or-longer ultramarathons within the prior two years — this isn’t a race a first-time 100-mile finisher can simply sign up for. With a field capped at 146, it’s one of the most competitive lotteries in American ultrarunning.
