What is Dirt Circus?

Did you know that there are thousands of small local trail running events across the United States each year?

Our goal is to connect runners with races and with one another, to highlight race directors, running stores, coaches, and the other local businesses that make up the fabric of our trail running community. The best way we know how to do that is by going for a run together. This sport is a little wild and we like it that way, so come join the Dirt Circus with us.

Meet with race directors, find your next event, run with friends, win prizes and more. Think of it as a live and in-person version of ultrasignup.com, but even more fun.

Why a Circus? Once upon a time, ultrarunning looked a little different. The sport has its roots in pedestrianism, where people would gather under the big top and walk and run for sport. Bets were made, the limits were pushed, and popularity soared. So come entertain yourselves with us, under the metaphorical big top.
