Hardrock 100 facts, tips
The Hardrock 100 was founded in 1992 as a tribute to the miners who worked in the San Juan Mountains.
The race allows pacers and crews.
At the finish, runners who complete the course kiss the eponymous Hardrock, an image of a ram’s head painted on mining debris.
Legendary ultrarunner Kilian Jornet has won the race five times, and holds the record for the fastest clockwise time. He has won the race the joint-most times along with American Karl Meltzer and Betsy Kalmeyer, who won the women’s race five time.

Race applications for the Hardrock 100 open in November on Ultrasignup HERE. A lottery then takes place for the 146 spaces available, split evenly between those who have finished and those who have never finished a Hardrock. The number of tickets a prospective entrant has in the race depends on how long they have been waiting for a spot, or how many times they have finished it.
The race director also selects a small number of people from the lottery who were not selected each year to compete. Generally, this is to correct perceived omissions in the lottery such as a runner that has tried for many years to enter.
