The club was started in 1995 by Michael Brennan, then co-owner of Marathon Dynamics Inc. (MDI), a company formed to provide running clinics and personal coaching for runners of all levels. The club was created because participants in the first marathon clinic conducted by MDI in January 1995 wanted to keep running and socializing together. Word got out and the club grew. In 2008 the club changed its name from Marathon Dynamics Running Club to Toronto Running Club, its new name being less intimidating with the word ‘marathon’ out of it and more suitable given that many members don’t run marathons and may never. Thus everyone feels more welcome and they are!
