Remembrance And Celebration As The Boston Marathon ApproachesPlay
On Monday, the 121st Boston Marathon will be run, and the bib number worn by the first woman to run the marathon, Kathrine Switzer, will be retired.
But before that, a memorial for the 2013 Boston Marathon bombing will be happening on Saturday. Officials also outlined today the safety and security protocols that will be in place throughout the marathon.
