Some 15,000 cyclists and 5,000 runners are expected to travel the Don Valley Parkway and Gardiner Expressway Sunday for the Becel Ride for Heart in aid of the Heart and Stroke Foundation. Road closures will take place at 2 a.m.Sunday and run well into the afternoon. Police are recommending people take public transit to avoid extensive traffic congestion in the area, especially in the downtown core and on arterial roadways. Every dollar raised by pledges is said to go to research. The Foundation’s goal is to raise $7 million this year for heart disease research.
