Kenyan John Korir won the Boston Marathon on Monday for the second straight year, breaking the course record in two hours, one minute and 52 seconds.
It was a Kenyan sweep at the world's oldest marathon as defending champion Sharon Lokedi won the women's race in two hours, 18 minutes and 51 seconds.
She set the course record last year in 2:17:22.
In the men's race, a relaxed Korir surged past Ethiopia's Milkesha Mengesha at the 20-mile mark to take control of the race.
Korir ran alone for the final six miles, breaking the record set in 2011 by compatriot Geoffrey Mutai in 2:03:02.
