Mark is Chief Running Officer of Great Runs, the ultimate guide to the best places to run in destinations worldwide. The website and responsive mobile app features curated running routes across thousands of unique locations, all researched by a global team of editors. A lifelong recreational runner and outdoors enthusiast, Mark is also the author of three running guide books, including Great Runs in Boston. While not a seasoned racer or marathoner, Mark is in the midst of a self-developed ‘personal fitness challenge’ of consecutive days of vigorous activity, now going on eight years. Mark has also had a long career as a telecom industry executive and consultant. He lives with his wife in Brookline, MA — flush by the 23 mile mark of the Boston Marathon.
