The 2021 Hardrock 100: What You Need To Know

Race Start: 6am (MT) Friday, July 16   
San Juan Mountains, Silverton, Colorado 

The Hardrock 100 is one of the most iconic 100 milers featuring 33,000 feet of elevation gain and loss at high altitude over brutally beautiful terrain in Southwest Colorado. It features steep competition and a field size limited to only ~145 runners. The 2018 Winners – when the race last ran – are MUIR Athletes Sabrina Stanley and Jeff Browning. They’re both racing again this year.

How to follow along:


Sabrina Stanley

Sabrina Stanley dominates in the most grueling of mountain ultra marathons, where her determination, dedicated training, and competitive spirit pay off. At just 31, Sabrina’s already earned her place on the podium at many high profile, notoriously brutal ultra marathons, and she’s just getting started.

Sabrina lives and trains in Silverton, Colorado with her partner Avery Collins, who is also an accomplished ultra runner as well. They both use real food to power their runs, and spend long days in the San Juan Mountains.

She’s set to race the Hardrock 100 Mile Run as the defending champion, where she’ll face steep competition from Courtney Dauwalter – a legend in the making –and Darcy Piceu, the Queen of Hardrock.

Also known as ‘Bronco Billy’, Jeff Browning is an icon in the ultra running world. He’s known for consistently placing well in races with stacked fields, finishing over 100 ultramarathons, his low carb high fat approach to nutrition, and his unique and recognizable style on the trail.

Jeff lives and trains in Flagstaff, Arizona, with his wife and children, with the Grand Canyon in his backyard and a community flush with running culture. He’s committed to a clean, intentional diet, and incorporates real food into his fueling strategy as well.

He’s racing as the defending champion in this year’s Hardrock 100 against a competitive men’s field that includes Frenchman Francois D’haene and American Dylan Bowman, among other elite competitors.
