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.

The 50k adventure consists of 2 (approximate) 10 mile loops throughout Rib Mountain terrain. After the first loop, you turn around and head in the opposite direction the second time. Resist the urge to spend it all in the first lap and test your endurance by attempting to achieve the fastest second loop split! Experience the mountain with new legs and eyes…and have a second chance to curse at those *&%^$(@ hills you “loved” the first time through. Even better, take the opportunity to support other runners in passing. And remember, there will be fully stocked aid stations approximately every 5 miles. After the second loop, it’s time to make one last trip to the top, take a selfie, have some final quality time with the woods and hammer some pavement for the remaining 9 miles of well marked, traffic controlled roads and pedestrian trails.

The 15k adventure will consist of the 50k route’s final climb and descent onto the road portion. Again, you’ll never go more than 5 miles without an aid station.

Be careful, the volunteers are the best in the business, you may easily fall in love with them — consider this your warning.
