Runners follow a loop course for the half marathon and the 5K, which start and finish at the Lost Valley Ski Resort on the western side of Lake Auburn. From there, the course makes a clockwise loop around the lake, taking runners along Whitman Spring Road, Lake Shore Drive, Turner Road, and Gracelawn Road (where the race’s biggest hills occur) before heading back to the ski resort and the finish line.
