Ironbull Ultra Trail

The Ironbull Ultra Trail event, known as the Rib Mountain Trail Races, takes place in Wausau, Wisconsin, at Rib Mountain State Park. It features three race distances: a challenging 50k consisting of three loops with over 7,000 feet of elevation gain, a 25k with 1.5 loops, and a 15k single loop with more than 2,500 feet of climbing. The course offers technical single-track trails and scenic views beneath colorful hardwoods, starting and finishing near Granite Peak Ski Area.

Aid stations support runners along the route. Post-race festivities include food, music, and local craft beer at the Sundance Chalet, celebrating finishers and volunteers. Visit the organization's website for the most recent information.
