It starts and finishes at the Silver Comet Trail Head on Floyd Road in Mableton, follows the trail west across a string of road crossings, and turns around between the Old Lost Mountain Road bridge and the Charles Harris overpass. The course has no turns, runs on the Saturday of race weekend alongside the marathon, and is USATF-certified.
