Toronto Waterfront Marathon

The Toronto Waterfront Marathon attracts over 25,000 runners to Toronto, Canada.

It is a World Athletics Gold Label race and is run on a fast, flat course that takes in the city center and (unsurprisingly) the waterfront of Lake Ontario.

The organisers also offer a half marathon and 5k race distance.

Once you've finished running you can take a visit to the world famous CN Tower or chill out in one of Toronto's urban parks.
