Drawing an impressive weekend of road running to a close, Brigid Kosgei has broken the women's marathon world record.
She won the Chicago Marathon with a time of 2:14:04, smashing British athlete Paula Radcliffe's 2003 record of 2:15:25.
It came just a day after fellow Kenyan Eliud Kipchoge became the first man to cover 26.2 miles within two hours, clocking 1:59:41 in Vienna.
However, unlike Kipchoge’s performance, Kosgei’s mark was set in an official race on a record-eligible course.
Kosgei, who won the Chicago race last year in 2:18:35, improved her personal best to win the London Marathon earlier this year with a time of 2:18:20.
She set out at a blisteringly fast pace from the off, covering the first 5km in 15:28.
Kenyan Lawrence Cherono sprinted past Ethiopian Dejene Debela to win the men's race in Chicago.
British defending champion Mo Farah placed eighth in 2:09.58..
