Beatrice Chepkoech broke the world 5km record at the Monaco Run on Sunday clocking 14 minutes 43 seconds.
The performance by the 29-year-old Kenyan bettered the previous record in a mixed gender race of 14:48 set by Caroline Kipkirui in 2018.
The time was also one second faster than Sifan Hassan's 14:44 record for a women's-only race, the previous World Record introduced in 2017.
Chepkoech battled strong winds during the early stages of the race along the Monaco coastline but fought on over the latter stages to claim a second world record, this one joining her 8:44.32 record in the 3000m steeplechase set in 2018, also in Monaco.
"I'm so happy because I didn't expect it," said Chepkoech, the 2019 world steeplechase champion. "It was cold and there was a lot of wind, but I tried to follow my pacemaker and everything was perfect."
Joshua Cheptegei of Uganda, who set the men's world record of 13 minutes 14 seconds.
