A jogger runs through the sunshine under a bridge at Cedarvale Park in Toronto on March 11, 2012. Heather Gardner's 2009 move from Hamilton, Ont. to Toronto came with a few adjustments -- her workout routine among them. A longtime athlete, Gardner had gotten used to running with a group in Hamilton, which offered her a sense of community and a way to exercise for free. When she moved to Toronto, she started running on her own to stay active amid a job transition that kept her at a desk all day. THE CANADIAN PRESS/Pawel Dwulit
