Toronto Waterfront Marathon
Race Day Weather
Cool start, warming finish
Runners will face a temperature range from 41°F at the start to 63°F by the finish, with a steady increase throughout. Wind will be a factor with headwinds in the early miles, particularly from Miles 2 to 6, followed by a favorable tailwind from Miles 11 to 21. Runners should adjust their pacing in the initial segments to conserve energy for the later tailwind stretches, while staying hydrated as temps rise.

Race Info
The Toronto Waterfront Marathon runs through downtown Toronto and along the Lake Ontario waterfront every October, drawing more than 30,000 runners across the marathon, half marathon and 5K. The 42.195-kilometre course starts on Yonge Street near Elm Street and finishes on Bay Street near Queen Street, and its flat profile has made it a frequent stop for runners chasing Boston qualifying times. First run in 1999, the race carries World Athletics Elite Label status and serves as the Athletics Canada National Marathon Championships.
