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.

Ready for adventure? Our routes are designed to give riders the chance to explore the grit in the western portion of Marathon County on several gems that can only be accessed through this race. Riders will fully experience Central Wisconsin by riding through areas not usually open to bikes through “featured sections” in addition to passing ginseng fields, dairy farm pastures, barns, and farm fields in each the 50, 85 and 144 mile races. This event is part of the Ironbear 1000 which highlights Wisconsin’s epic gravel.
