The GoodLife Fitness Toronto Marathon will hit city streets on Sunday, the first time since the long-running race agreed to move from its traditional October slot.

Yonge Street, University Avenue and Lake Shore Boulevard are some of the routes that will be closed Sunday for the major event.

Race organizers moved the 42-year-old event to May 15 instead of holding it in the fall.

With the Scotiabank Toronto Waterfront Marathon held in late September, many commuters in the past complained about facing too many closures and diversions within too short a time.

Last September, then-mayoral candidate Rob Ford said he wanted to take marathons off city streets and put them in places such as High Park or Downsview Park.

The change in scheduling comes after council passed a motion to spread road closures out during the summer months.

With the GoodLife race this spring, closures will be spread throughout the year.

"We will be the first big event in Toronto next year, and we are looking forward to it," GoodLife Fitness Toronto Marathon Jay Glassman told CTV Toronto last fall.

The race begins at the North York Civic Centre at 8 a.m. on Sunday, before the crowd of runners makes their way south along Yonge Street and then weaves through the downtown core and west along Queen's Quay before making a return trip along the same route.

Last year, some 15,000 runners from 55 countries participated in the 42-kilometre marathon, half-marathon and five-kilometre run.

The race is expected to close Yonge Street from Finch Avenue to Bloor Street starting at 6 a.m. Sunday.

Some lane restrictions will also take place in the area bounded by Yonge Street in the east, Spadina Avenue in the west, Davenport in the south and Caplin Crescent in the north.

Intermittent closures will also affect Queen's Quay from York Street to Bathurst Street, Lake Shore Boulevard from Bathurst Street to Windermere Avenue and Queen's Park/University Avenue from Bloor Street to Queen's Quay.
