The DRvG 12-mile course includes 897ft. of climbing and starts/ends inside Upland Hills Farm. The route features 99% gravel roads dragging you up the Barr Road climb ascending through the iconic Grampian area and up through the Drahner Road climb which features the highest point in Oakland County at 1,250ft.  The course continues north along some of the most scenic gravel roads in the area before bringing you back to absolute chaos by dumping you into Bald Mt. North Recreation single track for some old-school riding before finally bringing you into the Upland Hills private land access road, which will be the deciding factor with its rough two-track and sandy/hilly terrain.
