Ready for adventure? Experience Xtreme Gravel which is anything we want it to be, combined with what Mother Nature decides it's going to be. 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.
