Run MDI Marathon 2024



The Mount Desert Island Marathon, Half & 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 the well-to-do village of Northeast Harbor. All three races finish on the quietside of MDI in the hardworking lobster fishing community of Southwest Harbor.

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

Community Impact:

The Mount Desert Island Marathon brought in a record $2,184,632.00 to the local economy in 2023, according to an economic impact study from the Maine Sports Commission.

“Crow Athletics’ events tell a unique story in each of their host communities, benefiting businesses, residents and creating race experiences for visitors to long remember… As Gary Allen, Crow Athletics, speaks of – ‘the ripple effects’ – resulting from a race,” explained Shelia Brennan Nee, Strategic Director of the Maine Sports Commission.

In addition to the significant economic impact to the local business community, the event also contributed a total of $45,138.00 to local nonprofit organizations in 2023, and annually funds two important scholarships at MDI High School.

“We are thrilled that our efforts continue to be one of leading event-based economic drivers in our island communities,” said race founder and director Gary Allen.
