It was Ethiopia’s Gudaf Tsegay who initially requested a world-record pace, though she would finish behind Chebet with a 29:05.92.

"When Gudaf asked for a world record, I decided to say ‘Let me try to go for that to see how the body is.’ Because my body was not bad," the world cross-country winner told World Athletics.

"I was comfortable to run a world record so when I saw Gudaf drop a bit, I said, ‘Let me try to push it to see how it can go.’ When I got to the last two laps, I just got motivated and said, I’m on a world record pace, so let me push the last 400m."

With the race also doubling as the selection race for Athletics Kenya’s Olympic team, Chebet has surely punched in her ticket to Paris, along with Lilian Kasait Rengeruk who qualified with a 29:26.89.

The US Olympic Track & Field trials are also coming up, and the biggest stars in track and field were in attendance including Sha'Carri Richardson, who won the women's 100m with a time of 10:83 and Christian Coleman who grabbed first place in the men’s 100m with a sub-10 time of 9:95.

UK’s Josh Kerr won the Bowerman Mile in a world-leading, personal-best time of 3:45.34. He beat Norway’s Jakob Ingebrigtsen, the 2020 Olympic 1500m champion and Kerr's vaunted adversary, who finished as a runner-up with a 3:45.60. 

"I felt very strong through the first (kilometre) and I was like, you know what, it’s time to press and push and see what these guys have got," Kerr said. 

"I tried to fight him," Ingebrigtsen said of Kerr.

"But today for me was more of a time trial. Of course, we’re racing, but it’s definitely some differences in terms of approach into this race because this, for some people, this is their final test, even before the Olympics in Paris. But this is not my final test. I think if anything, this is going to be an exciting summer. For myself, I think it’s very good."

Australian Jess Hull claimed an Oceania record in the 1500m, running 3:55.97 to finish second to Ethiopia's World Championship silver medallist Diribe Welteji, who ran a personal best of 3:53.75 in the event.

Another world lead was set in the 3000m steeplechase after Peruth Chemutai broke the Ugandan record in 8:55.09, three tenths of a second off of the previous world lead held by Beatrice Chepkoech, Saturday’s runner-up in 8:56.51. 

The Diamond League continues 30 May in the Oslo Bislett Games.
