- **Event Description**: The Mount Desert Island Marathon, Half &amp; Relay is North America’s premier destination road race. The award-winning course features miles of pristine terrain passing tranquil lakes, soaring mountains, sleepy Maine villages, and stunning seaside vistas —including Somes Sound, the only fjord on the Eastern Seaboard— all set against the awe-inspiring backdrop of Acadia National Park in peak fall foliage season. The Marathon and Team Relay start in the world-famous Bar Harbor, while the Half-Marathon starts in picturesque village of Northeast Harbor. All three races finish on the quietside of MDI in the hardworking maritime community of Southwest Harbor.

Hosted by Crow Athletics and held annually the weekend following Indigenous Peoples’ Day, this fall classic has earned national and international accolades. Once you #RunMDI, you’ll see why!
