Spectating is a sport too. So what kind of spectator do you want to be?
The early-in-the-race spectator: The Framingham train station, at the 6.6-mile mark, is a good spot to go if you want an early glimpse of the athletes. You can then take an inbound commuter train to catch them again in Boston.
The scene chaser: If you want a scenic spot for cheering, head to the Natick town center at Mile 10. And if you want a really scene-y spot, head to Wellesley College at Mile 13 to witness the Wellesley “scream tunnel.” It’s even louder than you think.
The cheerleader: If you want to help the runners along, head for the Newton Hills between the 17.5-mile mark and Mile 21.
The “almost there” screamer: Please, please do not scream, “You’re almost there,” until runners are, in fact, almost there. What qualifies as almost there? From our vantage point: when you can see the finish line. If you want to catch runners in those final 600 yards, find a spot along Boylston Street.
