Our free Central Park runners map is so popular we decided to do the same favor for Boston. The Charles River is the most popular running place in Boston and Cambridge and it was once my regular running place. However, there are so many route choices using all the bridges that you really need a map with all the segment mileages (and, of course, all the other details like water fountains, T stations, etc.) So here is my map – download it free, print it, and carry a copy. The only thing we ask is that you simultaneously subscribe to our free newsletter (you can opt-out at any time). And please email us with any suggested map improvements.
