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.  Riders will fully experience Central Wisconsin by riding through areas not usually open to bikes in addition to passing ginseng fields, dairy farm pastures, barns, and farm fields in each the 50, 85 and 140 races.

If you’d like to be a part of the event but don’t want to spend hours on your bike, consider the 12 mile recreational ride, or volunteer! We offer a family friendly, timed, non-competitive ride in downtown Wausau for those wanting to participate in this event. This 12 mile route starts with a hill then is flat, totaling less than 400 feet of climbing for the entire route. All participants under age 18 are free!   140 mile, 85, and 50 mile gravel routes with 12 mile recreational ride
