The Boston Marathon expo is at once completely overwhelming (so many people!) and incredibly special (for obvious reasons). Between bar samples, treadmill tests, speaker series, photo ops and free beer, you could easily spend an afternoon in the hall. It’s also way to easy to drop loads of cash. Brands pull out all the stops to deliver sweet Boston-specific t-shirts, jackets, shoes, stuffed animals and more. Here’s some sweet gear from the show.
