WELCOME

Ultrarunning has a long and storied history in the U.S., and we believe in combining the best “old school” values with what is new and good in the sport. While these courses are among the most challenging out there, we believe anyone with the will and fortitude should be allowed the opportunity to test their mettle against them, so as of now, we don’t require any sort of qualifying run – just a willingness to suffer and give it your absolute best. And we hope you will enjoy our little event.


WE ARE A CHARITY RACE

Since 2012 the Run Rabbit Run has donated almost $700,000 to non-profit and charitable organizations. In 2025 we donated over $82,000 to 20 northern Colorado charities. These organizations’ volunteer efforts have made the Run Rabbit Run a success.

Bunny Money! What’s in the Purse for 2026?


The Run Rabbit Run 100 mile race offers one of the largest prize money purses you will find. Our $20,000 first place and $100,000 overall purse is one of the largest in the world and by far the largest in the USA.

What Our Competitors Say

“What a fantastic race. I’ve completed the 50 miler 12 times and look forward to it every year.” – Melissa Uchitelle-Rogers


“As a long time Steamboat resident and Run Rabbit Run runner since 2012, this race to me, means community. The trails are quiet and beautiful in the fall with golden aspens and crisp temperatures, the views are spectacular and the aid stations full of smiling faces, but it is the grass roots community. The camaraderie between the runners and the joy of accomplishing big things in an atmosphere that honors what trail running should be.” – Cara Marrs
