Thousands Run Boston Marathon Today [PHOTOS]

Thousands are preparing to run the Boston Marathon today, a year after the bombings that killed three people and injured many more. We wish everyone the best, whether they are running, walking, cheering or providing security in Boston.

Good luck to those running in the Boston Marathon today! #BostonStrong #NeverForget pic.twitter.com/eTzyTJvgrV
