Olympic medal prospect Stewart McSweyn has broken the Australian record for the mile and set his sights on the 1500-metres at the Tokyo Games.
McSweyn has eclipsed Craig Mottram's previous national benchmark to win the mile at the Oslo Diamond League meet.
He clocked three minutes 48.37 seconds, shaving 0.61 seconds from Mottram's previous mark set in 2005.
McSweyn's run is also the world's fastest mile since 2014.
The 26-year-old has qualified for the 1500m, 5000m and 10,000m events at the Tokyo Games starting July 23.
But he's turned his focus to the 1500m in a bid to join legends Herb Elliott (gold, 1960) and John Landy (bronze, 1956) as Australian medallists in the event at the Olympics.
"This probably shows I'm in good 1500m shape," McSweyn said.
"There's going to be a lot of great competitors in the field in Tokyo ... it's a loaded field but I'm confident that I'm in good shape to be competitive."
McSweyn's time for the mile in Oslo was the 22nd quickest in history.
The Tasmanian stuck to the pacemakers before launching in the final 600m metres to victory.
"I was really happy with how I executed that race," he said.
"I felt like I had a bit to give that last lap and I was able to run pretty well so I'm confident the season going towards Tokyo is going in the right direction."
McSweyn dedicated his Australian record to his former mentor and agent Maurie Plant who passed away last year.
"This is also a special meet for me," he said.
"A good friend of ours, this was his meet, Maurie Plant.
"When I was out there, I had a lot to give not only for myself but for him and his family.
"The mile was a special race for him so I was running with him on my mind as well so that definitely helped."
Fellow Australian Jye Edwards finished in third place in 3:49.27 to move to third on the Australian all-time list - he will join McSweyn in the 1500m in Tokyo.
Australia's reigning world javelin champion Kelsey-Lee Barber took third place in Oslo, throwing 60.86m, a week after winning in Finland.
Compatriot Hana Basic was fifth in the women's 100m in 11.42s while fellow Australian David McNeill posted a personal best in the 3000m of 7:39.43 to finish eighth.
