Newcomer Karsten Warholm delivered a stupendous home win over a 400 metres hurdles field including Olympic champion Kerron Clement and another Norwegian, 16-year-old Jakob Ingebrigtsen, won an under-20 race that had taken on the traditional Dream Mile billing in order to showcase his talent.

To round off a memorable evening at this fifth International Association of Athletics Federations (IAAF) Diamond League meeting of the season, Qatar's Mutaz Essa Barshim broke the 28-year-old stadium record set by world high jump record holder Javier Sotomayor as he cleared 2.38 metres.

There was joy also for two Britons who have set world mile records at Oslo, IAAF President Sebastian Coe and Steve Cram, here for the BBC, as they witnessed 22-year-old Jake Wightman defeat atop field to win the concluding 1500m in a personal best of 3min 34.17sec.

Oslo got the result it wanted as the under-20 Dream Mile went like a dream for Ingebrigtsen, who ran a beautifully controlled race to win in 3:56.29 - well inside the 3:58.07 he recorded at last month’s Eugene Diamond League to become the youngest sub-four minute miler in history.

But it also got the result it never really expected from its 21-year-old decathlete-turned-400m hurdler.

In maintaining his bold early charge all the way to the line, and lowering his own national record to 48.25sec, Warholm, who reached the Olympic semi-finals at Rio 2016 in his first year as a specialist hurdler, did more than could have been asked of him on an evening when one of the event’s legends, Ed Moses, was watching from the stand.

As Warholm, running in lane seven, came into the final straight in the lead, the crowd noise rose another level. Clement, running one lane inside him, was perfectly placed to move past, and it appeared likely that the young man would pay for his adrenaline-charged start.

But the 31-year-old American athlete’s challenge simply fell away in the closing 80 metres as he drifted all the way back to eighth.

The effort Warholm had expended, both physical and mental, was palpable at the finish. 

He remained a bent, exhausted figure just beyond the finish line for fully 10 minutes, face flushed, unable even to respond after Moses had come down from on high and offered him water.

Warholm was down so long even the photographers who had raced over towards him began to drift away. 

Who would have expected that he would have earned a round of applause from home followers for the simple act of standing up?

"It was really great doing it here at Bislett,"he eventually said.

"I felt strong and ran strong, but it was hard from the eighth hurdle. I was near the last hurdle and changed to 15 steps. 

"I had no more to give and that’s usually one of my strengths."

After assembling another stellar high jump field, Hoen - winner of this event here in 1994 with an effort of 2.35m - admitted: "I feel personally that I want to kill this record."

Lo, Qatar’s baby-faced assassin did the deed, having teetered on the brink of an earlier-than-hoped for exit with two failures at 2.35m before clearing at the last and then setting the meeting record of 2.38m at his second attempt, thus bettering by one centimetre the mark set in 1989 by the only man who has jumped higher than him, Cuba’s world record holder on 2.45m, Sotomayor.

"That was the target," said Barshim. 

"We came for 2.38. 

"So mission completed. 

"At the beginning I was feeling little bit sleepy, but after 2.33 I woke up and came into the right rhythm."

The concluding men’s 1500m - involving a field that would normally have raced under the traditional banner of a Dream Mile had that not been transferred to the under-20 race here involving Ingebrigtsen - produced a breakthrough victory for Wightman, who took more than a second off his personal best of 3:35.49.

In his wake the Briton left some of the world’s most accomplished middle-distance runners, with Kenya’s Elijah Manangoi, who has a personal best of 3:29.67, finishing second in 3:34.30 and the hugely experienced Polish athlete Marcin Lewandowski third in a personal best of 3:34.60.

It was a night to remember for the boy whose parents Susan Tooby and Geoff Wightman - also his coach - were both successful international marathon runners.

There was embarrassment for the organisers as world 200m champion Dafne Schippers, awarded a special Oslo medal for her recent performances  after coming home first in the 200m in 22.31 and also serenaded with "Happy Birthday" on the day she turned 25, then learned she had been disqualified for an earlier false start.

But the Dutch athlete, who had run under protest, belatedly regained her victory on appeal after claiming she had been put off by someone close by standing up and banging their seat back. 

"It was noisy at the start, so much noise, very hard to concentrate," she said.

Canada’s Olympic 100m bronze medallist Andre de Grasse - just - held off the challenge of his sometime training partner Chijindu Ujah to retain his 100m title in Oslo, clocking 10.01, with the Briton clocking 10.02.
