Tomorrow (Sunday, May 5, 2013) will see the complex running of the GoodLife Fitness Toronto Marathon, although the name should be in the plural. Some 12,000 runners will take part in four events: two of them, the full Marathon and the Half-marathon will come down Yonge Street. The Marathon will find its way down Rosedale Valley Road to Bayview Ave. (map). A heads up for anyone likely to be driving down that way. The police seem to have thrown a wide net of warning across the city with the possibility of “lane restrictions” all the way from Etobicoke in the west to Bayview Ave. in the east. Let’s hope it is not as serious as it sounds. Two other events, the Mel Lastman 5K and the Ontario Place Relay, occur on the Lakeshore. The DVParkway Bayview/Bloor off-ramp to southbound Bayview Avenue will be closed Road closures will also be in effect this weekend in Mississauga for that city’s marathon and related events. Race Maps
