Beatrice Chepkoech of Kenya smashed the 3,000-metre steeplechase world record by more than eight seconds in 8 minutes 44.32 seconds at the Herculis Diamond League meeting in Monoco on Friday.
Chepkoech improved the previous mark of 8:52.78 set by Ruth Jebet of Bahrain two years ago in Paris.
She also won the race by more than 16 seconds. Nevertheless, runner-up Courtney Frerichs crossed the finish line in 9:00.85 to set the American record.
Chepkoech broke the record just hours after the IAAF announced Jebet, the Olympic champion, was among 109 athletes and coaches facing disciplinary action for doping and other offences. Jebet was on a list of athletes provisionally suspended after a positive test for EPO in February.
