Finishers' Poster Stamping

Finishers can make the Boston Marathon feel a little more official with a free commemorative poster and a hand-stamped finish time at The Trackhouse. The setup is simple and celebratory: pick up a poster (one per runner) and get the time stamped on the spot—whether it’s a PR worth framing or a hard-earned badge of survival. Poster stamping runs Monday post-race and continues Tuesday while supplies last, with posters available first-come, first-served, so early arrival is the best bet.
