Runners follow an out-and-back loop course at the San Juan Island Half Marathon, which starts and finishes at Lakedale Resort overlooking Neva Lake and Dream Lake. From there, the race follows a clockwise loop around the island, unfolding along Roche Harbor Road, Beaverton Valley Road, West Valley Road and then again on Roche Harbor Road before turning in to Lakedale Resort again to cross the race finish line.
