Course Map: Great South Bay Half Marathon

Runners follow an out-and-back course for all three races at the Great South Bay Run, which starts at the corner of Bay View Avenue and South Clinton Avenue, and finishes in Bay Shore Manor Park. In between the race start and finish line, runners follow a winding route through this town on the southern shore of Long Island, along many of its quaint, cozy downtown streets, including Main Street and past Walker Park and Gardiners County Park.
