Jakob Ingebrigtsen running at the 2018 Payton Jordan Cardinal Invitational.
Norwegian Jakob Ingebrigtsen improved on his own 17-year-old world age group record on Friday at the Monaco Diamond League meet.
Ingebrigtsen held the previous record of 3:36.06 from the Oslo Diamond League meet. He improved that record by more than five seconds cruising to a 3:31.18 on Friday.
"It was great to do a PB of 3:31. I was hoping to do maybe 3:35, but it is astonishing to do this on the back of World U20 Championships," Ingebrigtsen said.
This race comes right on the heels of Ingebrigtsen running at the IAAF World U20 Championships in
Tampere, Finland, just last week. At that meet, Ingebrigtsen placed second in the 1500m running 3:41.89, and third in the 5K running 13:20.78 for a new AU20 record.
Ingebrigtsen finished fourth overall in the race behind Timothy Cheruiyot of Kenya (3:28.41), Elijah Motonei Manangoi of Kenya (3:29.64), and his brother Filip Ingebrigtsen (3:30.01).
His time ranks him as the fifth-fastest junior all-time and gives him the seventh-fastest performance all-time. He ranks only behind Kenyans Ronald Kwemoi (3:28.81), Robert Biwott (3:30.10), and Cornelius Chirchir (3:30.24 and 3:30.88), and Ethiopian Mulugeta Wondimu (3:31.13).
