Bar Harbor Bank & Trust Half Marathon & Fall 5K

Saturday, September 14, 2024 • Bar Harbor, ME • Course Map

Set for its 46th annual running through Maine’s Acadia National Park, whose 47,000 acres encompass most of the island on which it sits, this race is the only one of its kind that actually runs through the grounds of a U.S. national park, and takes place at a time when the autumn leaves are turning brilliant shades of orange, red and gold.

The earliest inhabitants of Maine’s Mount Desert Island, where the race takes place, were known as the Wabanaki, and are said to have given it the name “Pemetic,” which means “the sloping land.”

You’ll find out what they mean when you travel here, as it’s filled with hills and mountains, perhaps none better known than Cadillac Mountain in the center of the island.

That’s just part of the scenery you’ll find at the race, which follows an out-and-back course that starts and finishes in Bar Harbor next to the Mount Desert Island YMCA on Park Street.

While the half marathon will start on Main Street and continue north from there, the finish line lies in the athletic fields across Park Street from the Y.

From the starting line downtown, runners will head north along Main Street and turn left on West Street, where they’ll begin making their way toward Acadia. There’s one last turn on Duck Brook Road before they enter the park, and then begin running some 9 miles along its carriage roads.

The philanthropist John D. Rockefeller built some 45 miles of these carriage roads through Acadia between 1913 and 1940, and through the past century they’ve offered a way for “city-folk” to escape the urban jungle to get away to the park’s seashores, forests and lakes, and today are filled with walkers, hikers, bicycles and horse-drawn carriages — but no cars.

The race goes north and then turns south again on the carriage roads to take runners nearly all the way around Witch Hole Pond and Paradise Hill, a stretch that also features the biggest uphill of the race, a 180-ft. climb between miles 7 and 8.

Know that you’ll be running through history when you run through Acadia, as Mount Desert Island was first visited by Europeans in 1604, when a Frenchman named Samuel Champlain led an expedition here.

Writing about the place in his journal, he noted “the mountain summits are all bare and rocky… I name it Isles des Monts Déserts.” (That was about 16 years before the Pilgrims landed at Plymouth Rock.)

After the mile 8 peak, the race heads downhill again and then south toward the Eagle Lake carriage road entrance, which offers up some of the most beautiful scenery of the route.

Once you make it to the top of the lake, between miles 10 and 11 you head off the carriage roads and back onto Eagle Lake Road, which takes you out of the park and back into Bar Harbor for the race finish.

Make sure to register early — due to the fact that such a big stretch of the race route is located inside Acadia National Park, the half marathon is limited to 400 participants. That means you’ll have plenty of “elbow room” when you’re out on the course, organizers say.
