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 State Park. Sounds like “a walk in the park” so far, right? IRONBULL™ racers will partake in the challenge of steep climbs up and down the ski runs of Granite Peak and forested rock scrambles that will bring your PR to a screeching halt and evoke that wonderful feeling of just being a kid again, adventuring in the forest.
