The Champlain Islands Marathon runs on Sunday, October 17, 2027 in South Hero, Vermont, and the half marathon starts at the same time, 8:30 AM, in front of Folsom Elementary School. The marathon is two out-and-backs of the half marathon course along the west shore of South Hero and Grand Isle, past farms, apple orchards and summer cottages. The terrain is flat to rolling and the entire course is paved. The course is USATF certified, so it can be used to qualify for the Boston Marathon, and the time limit is 6 hours. Every finisher receives a medal and every participant a race shirt. The event has sold out in recent years and is capped at 500 runners across both distances. Registration opens November 29, 2026, and the race does not offer refunds, deferrals or bib transfers.
