TCS Toronto Waterfront Marathon 2026

The TCS Toronto Waterfront Marathon, held in October, is Canada's largest marathon event. It includes a marathon, half marathon, and 5K race. The marathon and half marathon begin together at 8:00 AM, with the 5K starting at 9:00 AM on the preceding day. The race information does not provide a course map, but the event's focus is on its waterfront setting in Toronto. The marathon and half marathon are sold out, but 5K registrations are still open. Marathon Tours is a participating entity, and TCS serves as the title sponsor.
