The return of the Bay of Fundy International Marathon

Lubec, Maine and Campobello, New Brunswick

June 21, 2026

The communities that share an international border and the Bay of Fundy are excited to announce the return of the Bay of Fundy International Marathon (BFIM) for Sunday, June 21, 2026.

The event features the best of Downeast Maine and Atlantic Maritimes. The committee is excited to be offering a race weekend including a marathon, half marathon and 10k events that showcases and strengthens our local communities.

We offer a thrilling marathon weekend, in one of the most peaceful and captivating corners of North America.  Lubec and Campobello Island share shorelines, clean salty air, cool June temperatures, and lighthouses that have guided the way for mariners and visitors for generations. The return of the Bay of Fundy International Marathon is your chance to join the adventure and experience this tradition.

Starting at the most easterly point in the USA, West Quoddy Lighthouse, the rolling Marathon course offers miles of water and harbor views. Crossing from the International border by way of the Franklin Delano Roosevelt Memorial Bridge and Lubec Narrows, the course takes runners past the President's summer home in Roosevelt Campobello International Park. Traversing stunning Campobello Island over to Head Harbor Light, the course then retraces its steps back across the bridge to finish along Water Street in the heart of Lubec.

What Runners are saying
"It was one of the more challenging courses and beautiful!"

"I loved the new course! Starting at West Quoddy is beautiful. Running through the trails was great--sheltered, soft terrain, great scenery"

"I loved every second! Beautifully organized"


Where to stay
We recommend you book early. Note that the local border stations are open 24 hours a day, 7 days a week, so you may choose your accommodations and access the race event from either side of the border. Lists of local accommodations can be found on:  Visit Campobello,  Visit Lubec. If your a last minute kind of person, Cobscook Institute has rooms, dorm style. Further afield (25 miles or so) is the Cobscook Bay State Park, and there is lots more accommodation in Machias, Eastport, and St. Stephen.

Border Clearances
Runners in the marathon,  and half marathon do not need to stop at the border as they cross between Canada and the USA  during the race, but they are still subject to the normal entry requirements of both countries and must be pre-cleared by both border agencies ahead of time. Runners who have not been pre-cleared will not be allowed to collect a race bib or run in the marathon or half marathon.

During the race, bibs must be clearly visible at all times, but particularly as runners pass through the border stations.

1) Runners are required to supply their passport or travel document information as far in advance as possible.  This should  be entered online during registration. This is the same process most airline passengers go through when traveling on international flights. All documentation information is kept securely and in confidence by race officials and supplied only to the official Canadian and USA Border Services for race pre-clearance purposes.

2) Runners must pass through and be cleared by both the Campobello Island and Lubec border stations on either the Friday or Saturday before the race. As they do so, they should identify themselves as runners and be sure both border agencies check them off on their lists. We facilitate this process by having packet pickup in Lubec and bib pickup on Campobello Island.

3) Race bibs are valid for crossing the borders only during the race itself. If you are crossing the border at any other time than during the race itself you must present normal documentation. This includes getting to the Start and getting back to your accommodation on Race Day if you have to cross the border. You do not need to carry documentation during the race.

Please note that both border agencies are being extremely helpful and cooperative and going out of their way to enable this event, but they will still be enforcing normal travel requirements. Entry requirements for Canada and the USA are not the same, and it is recommended that runners who have any doubts regarding their entry to one or the other check these before they register.
