TCS Toronto Waterfront Marathon

The TCS Toronto Waterfront Marathon takes place in Toronto, Canada, along the city's lakefront in October. The setting combines urban infrastructure with proximity to water, offering runners the experience of a big-city race with the appeal of a waterfront route. The area sits at relatively low elevation, ranging from about 74 to 139 meters above sea level, so there's no concern about altitude adjustments or significant elevation challenges. The course is a trail-based marathon that stays predominantly flat with gentle rolling sections throughout the 42.2-kilometer distance. With only 153 meters of elevation gain across the entire route, runners can expect a steady effort without major climbs or descents to worry about. The terrain should feel forgiving underfoot, which is typical of waterfront trail courses, and the gentle rolling character means you won't face any surprises late in the race. It's the kind of course that rewards consistent pacing rather than tactical climbing or descending skills, making it suitable for runners targeting a strong time or those simply wanting a smooth race day experience.
