Norwegian Jakob Ingebrigtsen, who at 16 is already the youngest sub-4-minute miler in history, lowered that mark by another two seconds at a Diamond League meet in Oslo on Thursday.
Ingebrigtsen won a mile race in 3 minutes, 56.29 seconds. Three weeks ago, Ingebrigtsen became the youngest man to break four minutes in the mile by running 3:58.07 at the Prefontaine Classic in Eugene.
“I believe that I could run at least one second faster [than at the Pre Classic] if I had the right pace from the beginning, so I’m really happy,” Ingebrigtsen said Thursday.
