why ironbull ultra trail?
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.
Rated by Strambecco as one of the 2024 Best Trail Running Events in the Midwest, 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!
Do you have the endurance and strength to finish this challenge?
