No event is more authentically Boston than the marathon. It brings the city together and, for a day, invites it to explore the neighborhoods that line the course. From Hopkinton to Boston, along every mile and for every block, this is the place to find information related to this uniquely Boston event. While it's easy to pick a spot, it's often difficult to find out about what's around each mile marker. Povo captures the collective knowledge of both runners and spectators to make it easy for anyone to access.
