8:20 a.m.:
Boston Marathon runners are arriving at the athletes village in Hopkinton, Massachusetts, and security is tight for the 119th running of the venerable race.
Police are patrolling the area with bomb-sniffing dogs. Authorities say more than 3,000 officers – uniformed and undercover – have been deployed for Monday’s marathon.
It’s the second edition since terrorist bombs killed three people and wounded more than 260 others at the finish line in 2013.
Among those waiting for the start of the 26.2-mile race was Jessica Colindres, a Guatemala native who lives in Massachusetts and was stopped less than a mile from the finish in 2013 when police closed the course.
She says her goal is a “happy, healthy and safe” race.
