The summer calendar for horse racing in North America rolls on, with the marquee event this weekend taking place north of the U.S.-Canada border when the 164th running of the King’s Plate will be held Sunday, Aug. 20, at Woodbine in Toronto, Ontario. The first jewel of Canada’s Triple Crown anchors a stellar span of racing at Woodbine that also includes six other stakes races spread over Saturday, Aug. 19 and Sunday.
