World records for Duplantis and 3000m man Ingebrigtsen
Sweden's Armand Duplantis and Norway's Jakob Ingebrigtsen have both broken world records on a landmark day at the Silesia Diamond League meeting in Chorzow.
Duplantis broke the pole vault world record for the 10th time, edging his own landmark up to 6.26 metres after Ingebrigtsen had earlier on Sunday set a new 3000m mark of seven minutes 17.55 seconds at the Polish venue.
Duplantis eclipsed the 6.25m he cleared when retaining his Olympic gold medal in Paris earlier this month, and this was the third time this year he had progressed his own record.
The 24-year-old had brought the Stade de France crowd to their feet at the Paris Olympics when he broke the world record for a ninth time, but there was always the feeling that 'Mondo' was far from done yet.
At the Silesia Stadium, having gone over at six metres, he had the bar raised to 6.26 and the Polish crowd waited with bated breath.
His first effort was a poor one, but he then soared over at the next attempt before racing to the track and falling to the ground.
Olympic silver medallist Sam Kendricks of the United States cleared 6.00 before failing at 6.08 to take second, with Paris bronze-medal winner Emmanouil Karalis of Greece finishing third, also clearing six metres.
Australian Kurtis Marschall cleared 5.72m to finish seventh.
"I know a lot of people came here to see me jump, so I wanted to put in a good showing for them," Duplantis said.
"The record just came naturally because I was in good shape, so I am not surprised but I am thankful."
The crowd were already in the mood for something special after Ingebrigtsen shattered the long-standing 3000m mark by more than three seconds.
Ingebrigtsen eclipsed the record set by Kenya's Daniel Komen in 1996 when he clocked 7:20.67 in Rieti, Italy.
The 23-year-old's previous best over the distance came in September last year when he was nearly three seconds slower than Komen's mark.
He was left in shock when he crossed the line and looked at his time. Ingebrigtsen received a cheque for $US50,000 ($A73,500) and posed with it in front of the clock.
"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.
"3000 is a tough distance. After four-five laps you feel the lactic acid but you need to get going. The conditions were difficult with the heat today."
Three days earlier, Ingebrigtsen had exacted a small measure of revenge over Cole Hocker by winning the men's 1500m in Lausanne in 3:27.83, two weeks after the American had shocked the Olympic field to win gold in Paris.
