Earlier this week, Ingebrigtsen had exacted a modicum of revenge over American Cole Hocker by winning the 1500m at the Diamond League meeting in Lausanne.
The Norwegian lost his Olympic title over the distance to Hocker at Paris 2024, with Great Britain’s Josh Kerr second, but won 5,000m gold.
The 23-year-old carried that form into Sunday’s meet in Poland, although admitted he did not expect his world record time.
“It feels special, amazing. I was hoping to challenge the world record here, but based on my training, I can never predict exactly what kind of time I am capable of,” he said.
“I would not have imagined I could run 7:17, though. At the beginning the pace felt really fast, but then I started to feel my way into the race and found a good rhythm.
“Now I want to challenge world records at all distances, but it is one step at a time.”
Olympic 10,000m silver medallist Berihu Aregawi was second behind Ingebrigtsen in 7:21.28 – the third-fastest time in history – while fellow Ethiopian Yomif Kejelcha placed third (7:28.44).
