Who we are

We have created some of the most iconic road running, trail running, and road cycling events in the world. We came together to create the next legendary MTB race. We are Utah local who grew up hiking, biking, and camping on Antelope Island, and we think it’s time the rest of the world knew about the secret trails of Antelope Island.
