A point to point course, beginning in Rochford, the first 1.5 miles are on the road. At this point, the course becomes the Mickelson Trail. The next 12 miles are a mixture of gentle uphill and flat terrain. From this point to the end, the course is either downhill or flat and finishes at the historic Engine House at end of the line…the Deadwood Trailhead. The Half Marathon is also a point to point course, starting at the 13.1 mile mark of the full marathon. Walker Friendly .
