Toronto GoodLife Marathon

The Toronto Marathon, held annually on the first Sunday of May, is a race from Yonge and Sheppard, in the north end of Toronto, to Exhibition Place, via Humber Bay Park. The origins of the event trace back to 1977, and the race was initially called the Canadian International Marathon. In 2003, its name was changed to the Toronto Marathon. It was held previously on the third Sunday in October, the first Sunday after Canadian Thanksgiving, for 16 consecutive years. Because of concerns that another event was being held three weeks prior and led to too many road closures, as well as pressure from a major financial institution, the Toronto Marathon was moved to the first Sunday of May in 2012. The event was temporarily held mid-May in 2011, due to other events in the City of Toronto that year. Wikipedia
