TORONTO It’s a crisp winter morning, but the cold isn’t keeping Anne Mirgalet-Kennedy indoors. Several times a week, the Toronto woman joins the Midtown Raviners Athletic Club (MRAC) for hikes. “I like the physical challenge, and I like the social part,” says Mirgalet-Kennedy, who takes part in MRAC excursions several times a week. Sanjay Coehlo, meanwhile, says before joining the group, he had no idea what natural “treasures” Toronto possessed, referring to the city’s ravines and the Beltline Trail. Coehlo said, however, what’s almost as important to him now, is the sense of connection he gets from the group during what has otherwise been a time of social isolation.
