Marathon certified course (VT09006RF) begins and ends near the house where Clarence H. Demar (7 time Boston Marathon Winner) once lived, is out and back on the west shore of South Hero and Grand Isle; a land of farms, apple orchards and summer cottages. The terrain is flat to rolling and about half dirt road (hard packed and well maintained). The island is sparsely populated; traffic will be minimal; expect the possibility of wind due to the race's close proximity to the lake.
