Marathon Bombing & One Boston (2013)

On April 15, 2013, two bombs at the Marathon finish line killed three people and wounded hundreds. The city’s response — runners who kept running to give blood, the next year’s defiant race — became its modern self-definition. One Boston Day marks it each April 15.
