Acadia National Park Half Marathon

The Acadia Half Marathon course features breathtaking view of Acadia National Park and Maine’s rocky coastline. It is a Spectacular 13.1 mile course traveling on the scenic Acadia National Park Loop road. The second largest island on the eastern seaboard, Mount Desert Island boasts an impressive 41,000 acres of land devoted to the Northeast’s only National Park, Acadia – an amazing array of mountains and sea, cliffs and coastline.

This race is the MDI YMCA’s 2nd largest fundraiser of the year. Proceeds from the Half Marathon help fund our scholarship program. The MDI YMCA is the cornerstone of youth development and recreational activities on the island.

This half marathon is fortunate to be one of only a couple of races of its kind held in Acadia National Park. Walkers are able to enjoy the beauty of Acadia at a slower pace and are encouraged to participate! The event also features a 10k component.
