Thousands of runners are ready to take over 42.2 kilometres of the downtown core on Sunday for the Toronto Marathon.

The Goodlife Fitness Toronto Marathon, one of two marathons within the city, begins at Mel Lastman Square and, for those doing the entire race, goes as far as East Humber Bay Park before finishing at the Exhibition grounds. The race also has a half-marathon as well as a 5 km run and walk.

The race, which begins at 7:30 a.m. and runs into the afternoon hours, will close numerous streets and will also force a dozen TTC routes to change.
