American Meb Keflezighi won the Boston Marathon, a year after a bombing at the finish line left three dead and more than 260 people injured.
Keflezighi is a former New York City Marathon champion and Olympic medalist. He ran the 26.2 miles from Hopkinton to the finish on Boylston Street in Boston's Back Bay on Monday in 2 hours, 8 minutes, 37 seconds.
Keflezighi held off Wilson Chebet of Kenya who finished 11 seconds behind. The 38-year-old from San Diego looked over his shoulder several times over the final mile. After realizing he wouldn't be caught, he raised his sunglasses, began pumping his right fist and made the sign of the cross.
No U.S. runner had won the race since Lisa Larsen-Weidenbach took the women's title in 1985; the last American man to win was Greg Meyer in 1983.

Rita Jeptoo of Kenya successfully defended the women's title, finishing in a course-record 2 hours, 18 minutes, 57 seconds. She becomes the seventh three-time Boston Marathon champion.
Jeptoo broke away from a group of five runners at the 23-mile mark. Buzunesh Deba finished second with an unofficial time of 2:19:59.
American Shalane Flanagan finished fifth after leading for more than half the race. She took a gamble by setting the early pace. She ran her first mile in 5 minutes, 11 seconds, but fell back on the Newton Hills about 21 miles into the race.
Despite heightened security, the mood was festive at the finish line on Boylston Street. Spontaneous applause broke out as a group of Boston police officers walked near the site of last year's twin bombing and children danced as the Rolling Stones' song "Start Me Up" blared over the loudspeakers.
A total of 35,755 athletes entered the race — the second-largest field in its history, many of them coming to show support for the event and the city that was stunned by the attack on its signature sporting event.
"I can't imagine the number of emotions that are going to be there," said Katie O'Donnell, who was running the marathon last year and made it 25½ miles before she was stopped less than a mile from the finish line when the bombs exploded. "I think I'm going to start crying at the starting line and I'm not sure I'll stop until I cross the finish line."
The most obvious change for this edition of the world's oldest annual marathon was the heavy security presence. State and local police officers were everywhere, even on the rooftops of some buildings.
Helicopters circled above and bomb-sniffing dogs checked through trash cans. Yet for all the security, the atmosphere was calm and friendly.
"I think everybody is being very pleasant," said Jean Bertschman, a Hopkinton resident who comes to watch the start of the marathon most years and had never seen anything close to this level of security. "I think it's going to be a very good race."
Buses bearing the message "Boston Strong" dropped off runners. A banner on one building read: "You are Boston Strong. You Earned This."
Spectators went through tight security checkpoints before being allowed near Hopkinton Common.
Massachusetts Gov. Deval Patrick said officials were trying to keep a traditional family feel to the marathon while maintaining tight security.
As he started the mobility-impaired race, Patrick said he encountered a woman who had suffered a brain injury in last year's attack but was determined to run this year.
"Just before we set off the runners, she burst into tears," the governor said.
Runners attending the event will have to use clear plastic bags for their belongings, and fans hoping to watch near the finish line are encouraged to leave strollers and backpacks behind. More than 100 cameras have been installed along the route in Boston, and 50 or so "observation points" will be set up around the finish line "to monitor the crowd," the Boston Athletic Association said.
Race organizers expanded the field from its recent cap of 27,000 to make room for more than 5,000 runners who were still on the course last year at the time of the explosions, for friends and relatives of the victims and for those who made the case that they were "profoundly impacted" by the attack.
Lelisa Desisa of Ethiopia and Kenya's Rita Jeptoo, who crossed the finish line on Boylston Street about three hours before the explosions, will return to defend their championships. Desisa returned to Boston last fall to donate his first-place medal to the city as a gesture of support.
Jeptoo, who also won the race in 2006, said she is hoping for a third victory — and one she can enjoy.
"It was very difficult to be happy. People were injured and children died," she said of last year's marathon. "If I'm going to win again, I hope I can be happier and to show people, like I was supposed to last year."
Authorities say two ethnic Chechen brothers who lived in the former Soviet republic of Kyrgyzstan and the Dagestan region of Russia planned and orchestrated the marathon bombings with pressure-cooker bombs on April 15, 2013.
Tamerlan Tsarnaev, 26, died following a shootout with police days after the bombings. Dzhokhar Tsarnaev, 20, has pleaded not guilty to federal charges and is awaiting trial in which he faces a possible death sentence. Prosecutors say the brothers also killed MIT police officer Sean Collier days after the bombings in an attempt to steal his gun.
