BOSTON (AP) — Defending champion Evans Chebet has won the Boston Marathon again. He surged to the front at Heartbreak Hill to spoil the much-anticipated debut of world record holder Eliud Kipchoge and win in an unofficial time of 2 hours, 5 minutes, 54 seconds. Hellen Obiri won the women’s race in a sprint down Boylston Street to finish in an unofficial 2:21:38 and complete the Kenyan sweep. She is a two-time Olympic silver medalist in the 5,000 meters. The fastest ever fields in Boston included world record holders, Olympic and Paralympic medalists, winners of major marathons from 27 countries and a dozen Boston Marathon champions. (Photo: AP)
