The first year of the Run, Rabbit, Run 50 was in 2007. It was started by Fred Abramowitz as a charity run to benefit the kids (and other worthy causes) of northern Colorado, and to support the community of Steamboat Springs, so be sure to spend as much money as you can in our terrific little town. Betsy Kalmeyer designed the original 50 mile course (it has since been changed). In 2008 Paul Sachs became co-race director. The 100 mile run, featuring the highest purse money of any trail ultra in the world, began in 2012, and has since become among the world’s premier runs, attracting some of the world’s best ultrarunners – as well as first timers new to the sport – to the beautiful mountains of northern Colorado. We are so glad to have you.

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. We recognize opinions may vary as to how best to do that. 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.
