Toronto Waterfront Marathon

The Toronto Waterfront Marathon is an annual marathon held in Toronto, Ontario, Canada, in October. The race day also includes a half marathon and 5 km race.

The race is one of the elite label marathons in the World Athletics Label Road Races. At the 2013 edition of the race, race winner Deressa Chimsa broke the men's course record with the fastest marathon ever recorded on Canadian soil. In the 2011 edition of the race, race winner Koren Jelela Yal broke the women's course record with the fastest marathon ever recorded on Canadian soil. Canadian runner Ed Whitlock set multiple age group world records at the Waterfront Marathon, including a record in the 75 to 79 age group with a time of 3:08:35 in 2006, and a record in the 85 to 89 age group with a time of 3:56:33 in 2016.

In the 2018 race, Cam Levins broke Jerome Drayton's 43-year-old Canadian men's national record for the marathon, finishing fourth in 2:09:25, a 44-second improvement on the previous mark set by Drayton in 1975.

The 2020 in-person race was cancelled due to concerns surrounding the global COVID-19 coronavirus pandemic (as was the case for the May 2020 Goodlife Fitness Toronto Marathon event), although virtual races were to be held instead from October 1 to 31, 2020 instead.

In 2024, organizers announced that the marathon and half-marathon would occur on Sunday, and the 5K race will be held on the Saturday.
