Course and sustainability
The half marathon follows the Acadia National Park Loop road and runs along Maine’s rocky coastline with views of Acadia National Park. Mount Desert Island contains about 41,000 acres devoted to Acadia National Park. The organizer operates six water stations along the course.
The Mount Desert Island YMCA states a commitment to environmentally conscious racing. The event reports producing over 6,000 paper cups per race and is taking steps toward "cupless" events. For 2026 participants are encouraged to bring a reusable cup, handheld water bottle, or hydration pack; paper cups will still be available at all six water stations.
