The Acadia 70.8 Triathlon starts in the town of Mount Desert on the northern shore of Long Pond. The 1.2 mile swim heads out from Pond's End towards the Western Mountains of Acadia National Park. The 56 mile bike races the rolling backroads of Mount Desert Island through picturesque villages along the ocean, with beautiful views of Acadia's mountains, rock beaches, marshes, and ponds. The 13.6 mile run is scenic but challenging to finish at Mount Desert Island High School.

COVID Safety 

The MDI YMCA will be following all local, state and federal guidelines to ensure the safety of our participants, volunteers and community. This may include the use of masks, an after race snack bag to-go, and a rolling awards ceremony to decrease gathering sizes. Currently, the State of Maine requires all out of state visitors to complete a 10-day quarantine OR provide a negative COVID test taken no more than 3 days prior to arrival in Maine (NH and VT are exempt).

Since guidelines change weekly, we will be updating all participants with the final information as we get closer to Race Day.
