He sprinted down the main threat, the Ethiopian Hagos Gebrhiwet, in the riot and ran for the first time in 13 minutes.
It was a high-class race with seven runners in 13 minutes.
- It's absolutely fantastic.
I have run very fast in training.
Extra fun to do it in competition, says Ingebrigtsen.
Among those who were defeated was last year's sensation, the Ugandan Joshua Cheptegei, who set world records in both 5000 and 10000 m (12.35,36 and 26.11,00).
Ingebrigtsen lay down in the middle of the field and worked his way forward in the field.
Probably only 1500 meters in the Olympics
- I know that I have the capacity to do it, but there is a lot to do and it takes a little luck.
I got good help from the others in the race.
I'm one of the best in the world at 5000 meters and it's quite fun.
Ingebrigtsen won both 1500 and 5000 meters at the European Championships in Berlin 2018 as a 17-year-old.
However, there will probably be no doubles at the Olympics in Tokyo.
- We'll see.
It's a bad schedule.
It looks like it's only going to be 1500.
