IRONBULL Red Granite Grinder Bike Race

Riders get a chance to explore the grit in the western portion of Marathon County on several gems that can only be accessed through this race's 140 and 80 mile routes. Riders will fully experience Marathon County by riding through areas not usually open to bikes in addition to passing ginseng fields, dairy farm pastures, barns, and farm fields. 140 mile riders will be tested through a variety of hills, with the top male and female climbers being crowned “King / Queen of the Hill.” 30 mile route designed to showcase the area’s bicycle accommodations for all ability levels, including several dedicated bike & pedestrian paths. We welcome all ages on this family-friendly route – so bring the tag along / bike cart for the kids or tandem for your significant other.
