GMAA Green Mountain Marathon & Half Marathon
The Course: The certified marathon and half-marathon begin and end near the house where Clarence H. DeMar, seven-time Boston Marathon Winner, once lived. The half-marathon course 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 75% dirt road (hard packed and well maintained).
NEW IN 2021: The full marathon course is two laps of the half-marathon course. This helps us improve our logistics and provide a better experience for our racers.
