Cool start, mild conditions ahead

Runners will face temperatures starting at 46°F and reaching 55°F by the finish. With a light headwind from the SW at 10 mph, pacing adjustments may be necessary, particularly in the later miles. The humidity at 73% suggests a need for hydration, especially as temperatures rise.

Race Info

The Niagara Falls International Marathon began in 1974 as the Skylon International Marathon and originally started in Buffalo, New York before finishing across the border in Niagara Falls, Ontario. The race went on hiatus from 1987 to 1996 and relaunched in 1997, later carrying Casino Niagara sponsorship through 2008. Since 2022 the event has run entirely within Canada, following the Niagara Parkway past the American and Horseshoe Falls. The men's course record is 2:17:10, set by Peter Pfitzinger in 1980; the women's record is 2:37:08.6, set by Nicole Stevenson in 2004. Source
