Kenya's Olympic and world 1500m champion Faith Kipyegon said she was fit and ready to defend her title in Doha after edging Winnie Chebet in the Kenyan trials on Friday.
Kipyegon made a winning return to the track after a two-year maternity break at the Prefontaine Diamond League in June, but a hamstring injury in training interrupted her racing season.
"I thank God I have managed to come back stronger after the long maternity leave, and today I am able to win my race and book a ticket to the world championship," said Kipyegon, who timed her sprint perfectly to edge the African champion Chebet in the photo-finish.
"I am completely healed from the injury and ready to defend my title in Doha, where I expect to meet strong opposition from Genzebe Dibaba of Ethiopia and Sifan Hassan of the Netherlands."
