Defending champion Evans Chebet of Kenya won the Boston Marathon again on Monday, surging to the front at Heartbreak Hill to spoil the much-anticipated debut of world record holder Eliud Kipchoge and win in 2:05:54.

Hellen Obiri, a two-time Olympic silver medalist in the 5,000m, won the women's race in a sprint to finish in an unofficial 2:21:38 and complete the Kenyan sweep.
