SuperTri 10KTO

The Supertri 10KTO is Toronto's signature summer 10-kilometre road race, offering runners the rare opportunity to race on one of Canada's busiest urban highways completely free of traffic. Organized by Supertri, the event transforms the Gardiner Expressway into a fast, fully closed race course at sunrise, allowing thousands of runners to experience downtown Toronto from a perspective normally reserved for motorists. Since joining the Supertri event portfolio, 10KTO has evolved into one of Ontario's premier road races, combining elite competition with a welcoming atmosphere for recreational runners, corporate teams, and the city's thriving run club community.

The course begins at Exhibition Place before heading onto the Gardiner Expressway toward the iconic CN Tower, offering uninterrupted views of Toronto's skyline, Lake Ontario, Rogers Centre, and the city's waterfront. With long straightaways, minimal elevation change, and a professionally managed closed-road environment, the race has earned a reputation as one of the fastest 10K courses in Canada, making it an ideal venue for runners chasing personal bests. The early morning start also provides cooler racing conditions and a spectacular sunrise over the city skyline.
