The Boston Marathon Athletic Association Supporters T Shirt is for runners, fans, and supporters of one of the most prestigious annual road races in the world. From the elite field to the charity runners, from the spectators lining the course to the Heartbreak Hill regulars, the Boston Marathon has a community that spans generations. This running t shirt is for the people who show up year after year. It makes a great gift for the qualified marathoner, the spectator who picks the same Newton hill every April, the running club member, or the family supporter cheering from the sidelines. Wear it to training runs, race weekends, or casual everyday outings. ThreadSquad custom prints every shirt using direct-to-garment technology for vivid color and durability through training and beyond.
