Small-group Half Marathons

During times of a pandemic, we all have a desire to be in touch with the outdoors...perhaps even more than ever! We're trying something new- Small Group Half Marathons.

Run in the destinations you've always wanted to go to, but experience it in a more personal way. These events feature multiple race starts (at different times of the day) to reduce the crowds. Each location is tailored to follow state and local guidelines.

We invite you to join us and let us know what you think!

Since we launched in 2012 over 40,000 people have joined us at the world's most gorgeous locations to run, explore, and make lasting memories.

Stunningly well organized race experience. Everything about the day was just beautiful and well executed. So inspirational and fun, I would like to come work for you. Of course, it didn't hurt that I won my age group so my opinion might be slightly biased. ;)

I want to say how much I enjoyed both the Yellowstone and Glacier half marathons I ran last year, and if my knee starts cooperating I will participate in the Teton half this summer. They were both very well organized and had beautiful courses.

Can confirm, as a 2016 finisher of the Caldera Triple. Lifechanging great experience. See you in 2019 at Zion and Glacier! <3
