This was Beast of Big Creek 2026!
Watch the recap video of the return of skyrunning to the USA and North America's only stop on the Skyrunner World Series.

David Callahan, Co-CEO of UltraSignup shares a personal note on LinkedIn on the past few years of his ownership of the most important registration platform for the American trail and ultra running world:

When we bought it, UltraSignup worked, mostly. But it was like buying a house where every time you opened a door, you discovered another room that needed gutting. The technical debt was immense. The code was brittle. There were many white-knuckle moments for us through those early months and years.

But here’s what really kept me up at night: the trail running community had no idea who we were.

Really fascinating backstory that deserves a lot more visibility than being hidden inside Microsoft excuse of a social media platform.
