Course Description
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 route races through the rolling backroads of Mount Desert Island through picturesque villages along the ocean, with beautiful views of Acadia's mountains, rock beaches, marches, and ponds. The 13.6 mile run completes a scenic, but challenging, loop to finish on the MDI High School track.

The two closes to the area of the race are Somes Sound View Campground and Mount Desert Campground, but there are others such as Smugglers Den Campground and KOA Holiday.

No. Due to the limited amount of spaces in the race, and as this is one of the largest charitable fundraisers for the Mount Desert Island YMCA, race fees are non-refundable and non-transferable. If you discover you are unable to make the race we do ask that you contact us as numerous people wait on stand-by every year once we reach out cap.

Absolutely! Although we have a dedicated team of local volunteers, we can always use more help. We have all kinds of tasks for all ages. Kids can help with food prep; adults and kids can help out at water stations, at course monitoring and after race clean up. Contact the Race Director at
