Faith Kipyegon set a new 1500m world record in the Florence Diamond League meeting, with the Kenyan champion streaked clear to win in 3 minutes 49.11 seconds, breaking the 3:50 barrier for the first time. Ethiopia's Genzebe Dibaba set the previous record of 3:50.07 in 2015.
Kipyegon has won both world and Olympic gold on two occasions, but this is the first time she has broken the world record. She now holds the first and third fastest times in history, running her previous best of 3:50.37 last August.
