2026 Acadia Half Marathon and 10K

Join us for an awe-inspiring run set against the rugged beauty of Acadia National Park and Maine's iconic rocky coastline. This is more than just a race; it's a journey through the splendor of nature as you tackle the spectacular 13.1-mile course along the scenic Acadia National Park Loop road. With every stride, indulge in the unparalleled views that only Mount Desert Island can offer—the third largest island on the eastern seaboard with over 41,000 acres of majestic mountains, sea, cliffs, and coastline. Be swift and be one of the first 150 10k runners or take on the half marathon challenge to earn not just a medal at the finish line but also an exclusive event shirt. Remember to scoop up your packet at the MDI YMCA on the designated pick-up days—there's no race day pick-up—so plan ahead, as the finish line celebration wraps up at 10:30 am sharp!
