2026 TCS Toronto Waterfront Marathon

About the Event

The 2026 TCS Toronto Waterfront Marathon returns to the bustling streets of downtown Toronto on October 18th, Canada’s largest and most anticipated running event.

The course begins at Harbourfront Centre and winds through the vibrant neighborhoods of King West, St Lawrence Market, and ends by Victoria Park. Spectators gather along the route to cheer on participants, creating an electric atmosphere that makes every mile feel like a celebration.
The event has grown significantly over its decade-long history, attracting thousands of runners who range from elite athletes competing for national titles to casual enthusiasts seeking their first marathon finish line.
