Special Coverage: 2019 Boston Marathon

This morning, more than 30,000 runners took off from Hopkinton for the 123rd running of the Boston Marathon.

We check in on the race as thousands of runners cross the finish line in Copley Square, and reflect on the sixth anniversary of the Boston Marathon bombings. This year marks the first time the anniversary falls on the same day as the race itself.
