This past Sunday, we headed over to TD Garden for the 10th annual BFit Challenge, and honestly, the energy in that building never gets old. If you’ve never been, it’s a total rush—even if your legs are screaming by the end of it. The BFit Challenge is put on by the Boston Bruins Foundation, and it’s a pretty incredible sight. You’ve got firefighters in full gear, police officers, EMS, and military members all hitting the stairs to raise money for first responder charities.
