The Niagara Falls International Marathon sends runners along the Niagara Parkway toward one of the most dramatic finish lines in distance running, with the Horseshoe Falls as the backdrop. The weekend offers several distances, including a 5K, 10K, half marathon, and full marathon, making it accessible to first-timers and Boston-qualifying hopefuls alike.
For 2026 the entire course runs within Canada, a change from earlier editions that began on the U.S. side and crossed the Rainbow Bridge. Registration is online only, with separate portals for Canadian and international participants, so runners should sign up in advance rather than at race weekend.
