Standouts

---

A bucket-list, hilly point-to-point marathon along Acadia National Park's rugged Maine coast, starting in downtown Bar Harbor and finishing in Southwest Harbor, circling Somes Sound. The course is USATF-certified and a Boston Marathon qualifier, but the terrain makes it a hard, savor-the-scenery race rather than a BQ machine.

Why attend here

In mid-October, Acadia National Park is at its peak of autumn color, and the marathon route traces the granite shores and evergreen forests of Mount Desert Island, offering stunning blue Atlantic views and the unique Somes Sound fjord. After the race, warm up with a lobster roll or a bowl of clam chowder in Bar Harbor, then take a leisurely walk along the Shore Path to soak in the crisp, salty air and the fiery foliage that blankets the island.
