Competing at the Meeting de Paris, part of the Wanda Diamond League on July 7, Kipyegon set a new record of 3:49.04, shaving 0.07 seconds off her previous record of 3:49.11 set last year in Florence.
In a thrilling final race of the evening, the multiple world and Olympic champion faced strong competition from Australia's Jess Hull, who finished second with a time of 3:50.83. Hull's performance not only earned her a second-place finish but also broke her own Oceanian record, placing her fifth on the world all-time list.
"I knew the world record was possible because I recently ran very fast in Kenya," said Kipyegon, who clocked 3:53.98 at Kenya’s Olympic Trials. "I was coming here to just run my race and to see what shape I’m in to defend my title at the Olympics."
At 30 years old, Kipyegon is expected to bring her exceptional form to the Paris 2024 Olympics later this month, where she is a favourite to win multiple medals.
In 2023, Kipyegon was honoured as one of the World Athletes of the Year after setting world records in three distances during the season, including the 1500m, 5000m, and 1500m.
