Watch: Runners reclaim Boston Marathon one year after attacks
Tens of thousands of runners, cheered by a multitude of spectators, set off through the streets of Boston on Monday to reclaim the world’s oldest marathon from the fear left by last year’s deadly twin bombing.
More than 3,500 police, double the size of the force last year, and multiple government security agencies are keeping watch to prevent any replay of the ghastly carnage that visited the race on April 15, last year when two explosive devices tore through the crowds at the finish line.

“We want to show that the runner spirit is very resilient, and strong. This year we come back more and better than ever,” said Amby Burfoot, the 1968 winner who is running again at age 67 after being kept from finishing the last year race because of the attack.
