BOSTON -- Rita Jeptoo of Kenya successfully defended the Boston Marathon title she said she could not enjoy a year ago after the fatal bombings.

Jeptoo finished Monday's race 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 seventh after leading for more than half the race.

Lanni Marchant of London, Ont., was the top Canadian in 14th.
