Australian teenager Cameron Myers has run one of the dream miles of his life to earn a maiden podium finish in the Diamond League.

The 19-year-old produced a late burst to finish second in 3:48.87 at the Bislett Games in Oslo on Thursday, recording the third fastest time ever run by an under-20 athlete. 

Myers worked his way through the field after being shuffled back at the start and hit top gear in the home straight with only Portugal’s Isaac Nader (3:48.25) ahead of him.

The Canberran’s time was only behind his own U20 world record set indoors at 3:47.48 and Kenya’s Ronald Cheruiyot at 3:48.06 for an under-aged athlete.

“I’m frustrated,” Myers said after the race.

“I said before, I got myself in such a bad position and, you know, that’s my fault and my fault alone.

“I’ve gotta really work on getting out a little bit harder and putting myself in a position where I’m not gonna get knocked around as much as i did. So yeah, I’ll learn from that.”

He said he was happy with a second place and the time.

“But it wasn’t the race I was hoping to run.

I got a bit lucky it opened up for me in the last 100. I felt strong throughout but I never could get forward and get to the position I wanted.

“I really can’t be unhappy, I felt strong and had good power and speed at the end which is a great sign for me.”

Myers was joined by Kurtis Marschall on the podium after the Australian pole vaulter and world championships medallist rose to 5.82m for third. Olympic champion Armand Duplantis (Sweden) took gold with 6.15m.

The West Australian was pleased with his performance ahead of the short turnaround for the next Diamond League event in Stockholm on June 15.

“I had a great night tonight,” said Marschall. “I basically cleared 5.82 three attempts in a row and just brushed it off each time.

The good signs are there for my next competition in Stockholm in a few days.”

“I’m happy with the result but know that there is more height there for sure, so I will learn from this and keep building.”

Olympian Sarah Carli (NSW) marked her long-awaited Diamond League debut with a fifth-place finish in the 400m hurdles (55.13 secs), American Dalilah Muhammad cruising to a win in 53.34 secs.

Javelin thrower Mackenzie Little also finished fifth after a season’s best of 59.86m, while Stewart McSweyn returned to the international stage with a 16th place finish in the 5000m, grinding out the distance in 13:16.20.

Commonwealth champion Oliver Hoare faded to run 13th in 3:50.92 in the mile where compatriot Myers impressed most.

Meanwhile, Norwegian hurdling great Karsten Warholm destroyed his own world best time in the rarely run 300 metres hurdles by chasing down American Rai Benjamin in a stunning finish.

Roared on by the home crowd, the 2020 Olympic champion came off the corner behind Benjamin but roared past the man who had beaten him for Olympic gold last year in Paris to finish in a blistering 32.67 seconds, breaking his previous mark of 33.05 set in April.

Warholm ripped off his shirt and spun it around his head in delight when his record time was flashed on the screen.

“I never really went away of course, but it is good to be back for sure,” Warholm said. “I usually fade at the end of the 400, so the 300 suits me to some degree but I will be back strong in the 400 on Sunday.”
