Another World record for Kenya as Brigid Kosgei delivered a dizzying head-twister of a performance to blow away Paula Radcliffe’s world marathon record in the Chicago Marathon.
The Briton’s mark of 2hr 15min 25sec had stood, imperious and unchallenged, for 16 years. Yet Kosgei obliterated it by an astonishing 81 seconds recording a time of 2hr 14min 4sec.
Eliud Kipchoge’s run to become the first man to break two hours for 26.1 miles on Saturday could be the right motivation needed for the 25-year-old Kosgei blast which seemed unthinkable when dawn broke in chicago.
Her agent, Federico Rosa, has had a worrying number of banned athletes. They include Asbel Kiprop, the former world 1500m champion, Jemima Sumgong, the 2016 London marathon and Olympic champion, and Rita Jeptoo, who won this race in 2013. But there is no suggestion of wrongdoing by Kosgei or Rosa.
