Run Boston is a great way to get some exercise and tour the city. We were only in town for a few days, and I had read about Run Boston. Booking on line was very easy - and you could choose the route you wanted to run so it is possible to go longer distances. We chose the Freedom Trail run because we wanted to hit historical sites and see the city. Ronak was a great tour guide - we were able to tailor our run to include the Boston Marathon finish line so that our total run was a little over 4 miles. He was informative about the sites and took some great pics for us along the way. If you want to see the city, learn some informative facts and get exercise - you should definitely RUN BOSTON.
