Toronto Waterfront Marathon

The TCS Toronto Waterfront Marathon is a major running event staged in Toronto along the city’s scenic waterfront. Held in October, it offers Marathon, Half Marathon, and 5K distances. In 2025, both the Marathon and Half Marathon sold out, reflecting strong demand.

The race weekend features a dedicated expo, race kit pickup, and a comprehensive schedule of events, with options for elite competition, awards, and adaptive athletes. The event showcases Canadian Running Series branding and draws support from diverse sponsors and partners. It also highlights accessibility initiatives and environmental responsibility as part of its community-focused offerings. Visit the organization's website for the most recent information.
