BOSTON (AP) - One year after the deadly bombings, the Boston Marathon will launch today even stronger.

It's the second biggest field ever with 36,000 runners and a big boost in spectators is expected too.

Boston's mayor says there are no specific threats and security has been increased significantly to make sure it stays that way.
