The Acadia Half Marathon and 10K is one of our largest fundraisers of the year. The money raised through your entry fees help sustain the YMCA's scholarship programs, ensuring that individuals and families have access to the care, services, and programs that can help them improve their lives through healthy living or community activities. 

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 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!
