Origin Story
In 2020, UltraSignup sold to new owners, a group of runners who were amazed by how the trail running community rallied to support one another through the pandemic. They had an idea to celebrate trail running in a whole new way in late 2021, organized the first Trail Party. The response was incredible. The community was hungry to connect, to gather, to celebrate all things trail running. And so in 2023, we took all that enthusiasm and dreamed up the Dirt Circus.
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.
