Tens of thousands of runners, including some of the world’s best, crowded into Boston on a cold, lightly rainy Monday for the 119th running of the Boston Marathon.

Security was high near the start line in Hopkinton, along the 26.2 mile (42.16 km) course and around the finish line in Boston, in recognition of the bombing of the 2013 race, which killed three people and injured 264 in the one of the most visible attacks on U.S. soil since Sept. 11, 2001.
