The Hardrock 100 is on many trail runners’ bucket lists, and for good reason: This brutal 100-mile challenge, with upwards of 33,000 feet of climbing, wends its way through some of Colorado’s most beautiful mountain scenery.

This video, by Smartwool’s RoamTV, follows Darcy Piceu at the 2015 race. Piceu has run the race six times, winning three of those. (In 2015, she finished second after running a personal best of just under 29 hours.) Here, she explains the unique allure that brings her and many others back to Hardrock time and time again.
