BOSTON (AP) - The 118th running of the Boston Marathon has begun amid heavy security a year after the bombings near the race's finish line that killed three people and wounded more than 260 others.

The race began at 8:50 a.m. Monday for mobility-impaired marathoners and at 9:32 a.m. for elite women. The elite male runners start at 10 a.m.

Massachusetts Gov. Deval Patrick said at the starting line in Hopkinton that officials are trying to keep a traditional family feel to the marathon while maintaining tight security.

A moment of silence was observed and "America the Beautiful" was played over a loudspeaker before the start of the race.

About 36,000 runners registered for the race - the second-largest field in its history.
