The half marathon course uses historic carriage roads in Acadia National Park. Nine miles of the route follow hard-packed carriage-road trails built in the early 20th century. The course departs from Bar Harbor, climbs into the park, passes through dense forest, crosses several old granite bridges, and then returns to town. The terrain is described as hilly, with varied natural scenery along the route.
Walkers are welcome and able to enjoy the park scenery at a slower pace. There will be six water stations along the course; the organizer is working toward more sustainable practices and encourages participants to bring reusable cups, handheld bottles, or hydration packs. Paper cups will still be available at the water stations in 2026, and the YMCA notes the goal of reducing cup waste in future events.
MDI YMCA members may receive a coupon for reduced registration fees. Visit the organization's website for the most recent information.
