About the race

Champlain Islands Marathon & Half Marathon takes place in South Hero, Vermont, on the Lake Champlain Islands. It offers two paved, USATF-certified races—a marathon and a half-marathon—with Boston-qualifying potential. The course starts and finishes near the former home of Clarence H.

DeMar; the half-marathon is an out-and-back along the west shore of South Hero and Grand Isle, while the marathon adds a second out-and-back. Runners traverse flat to rolling terrain amid farms, apple orchards, and lakeside cottages. The event emphasizes a relaxed, community-driven atmosphere, medals for all finishers, shirts, multiple aid stations, and a cap of 500 runners.

No refunds or transfers. Visit the organization's website for the most recent information.
