The Mickelson Trail was originally the Burlington Northern rail line that took trains from Edgemont, SD to the northern Black Hills and the gold mines of the Deadwood area. The trail transverses the beautiful Black Hills of South Dakota. The surface is primarily crushed limestone and gravel, so you will have a consistent running surface throughout the event.
The trail is routinely groomed and maintained through out the year by a very dedicated staff who work for the South Dakota Game, Fish and Parks. With the Mickelson Trail being a former railroad bed, the climbs along the course are gentle but can last for a few miles. For more detailed information regarding the Geoge S. Mickelson Trail view Trail Info, to see a detailed description of every mile of the trail.
