Jakob will be the recordholder for U20 at 1500 with his 3.36,21 sunday. As some have stated Samuel Tefera ran 16/100 faster in january, but because of no doping-observers at his race it will not be ratified as record.
Here is a google translate of the article in Dagbladet, I could have done it better myself, but couldn't be bothered , and as always it is fun to read bad translations.
Jakob Ingebrigten can get the world order
The Super Race is likely to be the U-20 world record
It is clear that Jakob Ingebrigtsen's sparkling 1500 meters in the weekend's Nordic athletics match indoors will become a new world record in the U20 class, writes VG.
FEBRUARY 11, 2019 AT. 21.39 NTB .
Ingebrigtsen ran 3.36.21 in Bærums Idrettspark on Sunday. It was 16/100 seconds behind the time Samuel Teferas put in January, but now it turns out that the Ethiopian does not get the race approved as a world record by the International Athletics Association (IAAF).
"I can confirm that the record was not ratified, because there was no doping control on the competition day," says Jon Mulkeen of the IAAF to VG .
That means the Ingebrigtsen after all the sun marks becomes a new record holder. His name has already been listed on the IAAF's U20 list of records, but there he is listed with the old record-holder Ali Belal Mansoor (3.36.28). Only when the world record is finally approved will the 18-year-old from Sandnes stand alone.
