Niagara Falls Marathon

The Niagara Falls Marathon is held annually on a Sunday in late October in Niagara Falls, Ontario, with the full course entirely in Canada. The route follows the Niagara River and passes Horseshoe Falls, giving runners views of the falls and the surrounding gorge scenery. The event began in 1974 and was revived in 1998, and it is a Boston Marathon qualifier. A 10K, a half marathon and a 5K run alongside the marathon. Entries are limited in each distance and the event has sold out in 2026, with no wait list and no race-weekend sign-ups. Entries are non-refundable and non-deferrable, but bibs can be transferred before the deadline set by the organisers. Runners must be 18 or older on race day for the marathon, and the marathon course closes at 3:00 pm. Official partner hotels near the start and finish areas offer special rates, with a booking cutoff ahead of race day. Race day is typically cool and autumnal, so layers for the early start are sensible.
