Acadia National Park Half Marathon

Embark on an unforgettable running adventure at the Acadia National Park Half Marathon and 10K, set to take place on Sunday, June 7, 2026, in the charming coastal town of Bar Harbor, ME. This premier event, offering distances of 13.1M and 10K, invites runners to experience the breathtaking beauty of Acadia National Park, a rare opportunity as very few races are held within national parks. The race is a significant fundraiser for the MDI YMCA, supporting their vital scholarship programs.

The half marathon course is a spectacular 13.1-mile journey along the scenic Acadia National Park Loop Road, starting and finishing near the park entrance. Runners will follow the loop in a clockwise direction, encountering challenging terrain with varying elevation levels, including moderate elevation gain (approximately 274 meters of ascent) that earns it a "Moderate" difficulty classification. Throughout the race, participants are treated to panoramic vistas of Maine's rugged coastline, dense forests, and majestic mountains, passing iconic landmarks such as Sand Beach, Thunder Hole, and Otter Cliff. Typical race day conditions in early June offer pleasant temperatures, with highs around 68°F and lows around 49°F, and only a 17% chance of precipitation, creating ideal running weather.

Beyond the stunning scenery, the Acadia National Park Half Marathon is renowned for its welcoming atmosphere and commitment to sustainability. Aid stations are strategically placed approximately every two miles, offering water and Gatorade, though runners are encouraged to bring their own reusable cups or hydration packs for 2026 as part of the event's eco-conscious efforts. With a cap of 400 runners, this race often sells out early, a testament to its popularity and unique setting. Finishers of both distances receive a commemorative medal, and half marathon participants also receive a race shirt. This hilly yet incredibly rewarding course promises an experience that runners consistently praise for its unparalleled natural beauty.
