Kipyegon, who had already won a third world 1500m title here, duly added gold in the other championship event in which she has set a world record this year, thus becoming the first woman to win 1500m and 5000m titles at the same World Championships.
Kipeygon led a richly talented and closely packed field to the bell, at which point Olympic champion Sifan Hassan shuffled up to her side for the inevitable sprint-off. The running was steady until the start of the back straight, when the world record-holder took off, pursued by the Dutch runner and her teammate Beatrice Chebet, world silver medallist last year.
The Kenyan powered to the line, peerless, remorseless, giving the mercurial Hassan no glimmer of hope that she could improve upon silver.
Having won a third world 1500m title, Kipyegon now had a world gold in a distance she ran earlier this season for only the second time since 2015 and in which she lowered the world record to 14:05.20.
Her time here was 14:53.88, with Hassan second in 14:54.11 and Chebet in bronze medal position in 14:54.33.
