Walking/Running group in Cambridge, MA

Hey,

I used to be the biggest gym buff since joining the gym in August, 2012. I moved to Boston in September 2013 and as the days got harder, and I began to miss home, I began to stress eat and as such I've gained weight. The school's gym is closed and so I'm looking for an alternative to get some amount of exercise in over the Christmas Break. Is there anybody (beginners) who walk or run? I'd love company
