Race Information

Rib Mountain is a beauty to behold any season of the year. Whether you call it home, or if you are just passing through, you can’t help but admire this glacially eroded creation. But why observe from a distance what you can experience through all your senses?

Welcome to IRONBULL Ultra Trail.

What better way to discover than to dive right in the twists and climbs, running under a bounty of colored hardwoods on the gorgeous trails of Rib Mountain? Have your kids run the racetrack in the free Kocourek Kids run!
