Lower Don Parklands
Toronto, ON M4X 1B8
Pick up this run route near the Riverdale Farm--we supplied the address. Run down toward the highway in the valley and then head left (north) or right (south). Going right will take you toward the waterfront, along Bayview Ave. to Lake Shore Blvd. (head east if you like once reaching Lake Shore Blvd.). If you take the path north from the farm it meanders along Don Valley Parkway.
P.S. - The weblink is to the farm too.
