Bay of Fundy International Marathon 21 June 2026 (Canada site)

The Bay of Fundy International Marathon returns to Welshpool, New Brunswick on June 21st, 2026, bringing runners from across Canada and the United States together for a challenging yet scenic race through this coastal community.
Welshpool is nestled along the picturesque shores of the Bay of Fundy in eastern New Brunswick. The day's light will be soft as it filters through early morning mist over the oceanfront, casting long shadows on the winding streets that lead to the starting line near downtown Welshpool. As runners make their way out from the start area and onto the main thoroughfares leading north towards the international border bridge, they'll find themselves surrounded by quaint homes with gardens blooming in vibrant colors against a backdrop of gently rolling hills.
This year marks another milestone for the Bay of Fundy International Marathon as it continues its tradition of connecting communities across borders. Since its inception several years ago, this race has become an integral part of Welshpool's annual calendar, attracting runners from both sides of the international divide who come together to support local causes and celebrate their shared passion for running. Participants can look forward to crossing into the United States without stopping at a border checkpoint but must ensure they have proper travel documentation before registering.
The course itself winds through picturesque landscapes that offer runners stunning views of the Bay of Fundy's dramatic tides, which are among the highest in the world. The 42.2k marathon route begins and ends near the town square in Welshpool, with the half-marathon starting at a slightly later time from the same point but turning back after reaching an intermediate checkpoint just shy of crossing into Maine territory. Both distances feature smooth paved roads for much of their length, though there are stretches where runners will encounter softer surfaces as they traverse historic wooden bridges and follow trails alongside scenic waterways.
Starting near the town square in Welshpool with a gradual ascent up towards the international bridge, participants face minimal elevation changes overall throughout both full and half marathon routes. Aid stations stocked with refreshments appear regularly every few kilometers to keep competitors hydrated and fueled for their journey ahead. The 10k event remains entirely within Canadian borders but still offers runners plenty of opportunity to experience Welshpool's unique coastal charm.
With typical June weather averaging around 15 degrees Celsius, the race day atmosphere promises cool morning temperatures that gradually warm up as the sun climbs higher in the sky by late afternoon. A light breeze will help keep humidity levels comfortable for most participants while maintaining a chance of some scattered showers due to high moisture content in the air.
