Trail Races in South Dakota: The 6 Races Worth Training For
South Dakota racing is Black Hills country: the Black Hills 100 follows the Centennial Trail out of Sturgis and the Lean Horse 100 runs the Mickelson Trail near Custer. Expect granite hill terrain with real climbing on the Centennial Trail side and a smoother converted rail-trail on the Mickelson side.
