Just six weeks after winning in London on her marathon debut Hassan showed her extraordinary range in completing a winning double at this World Athletics Continental Tour Gold meeting, clocking 3min 58.12sec in the 1500 metres, with Kenya’s Nelly Chepchirchir second in 3:58.96.

The day before in the FBK Stadium the Dutch Olympic 5,000 and 10,000m champion had run 29:37.80, the fastest time of the year so far, to win the women's 10,000m.

"I had the marathon just six weeks ago and for me, the change was very hard so I wanted to see where I am," she said.

"I did it and I’m very happy with the time."

On June 6 2021 Hassan set a world record of 29:06.82 in Hengelo only for Ethiopia’s Letesenbet Gidey to lower it two days later on the same track to its current mark of 29:01.03.

Bol won the women’s 400m in a meeting record of 50.11sec to maintain her winning momentum as she builds towards a World Championships where she will seek to challenge the United States’ 400m hurdles defending champion and world record holder Sydney McLaughlin-Levrone.

The Olympic bronze medallist and world silver medallist, who lowered the longstanding women’s world indoor record to 49.26 on February 19 this year, had used her new stride pattern to winning effect two days earlier in clocking a 400m hurdles meeting record of 52.43 at the Diamond League Golden Gala meeting in Florence.

Duplantis pursued his normal course as he disposed of all his pole vault rivals early on - with Australia’s double Commonwealth champion Kurtis Marschall getting closest on 5.81m - before pushing on to see how close he could get to his world record, currently the 6.22m he cleared in February this year,

In adding one centimetre to his own meeting record the 22-year-old Swedish-American vaulter overhauled the American record and 2023 outdoor world-leading mark of 6.07m set two days earlier in Nashville by K C Lightfoot of the United States.

Lightfoot’s compatriot Grant Holloway, the double world 110m hurdles champion, maintained his winning run with a time of 13.03 from fellow American Devon Allen, who clocked 13.12.

Ukraine’s double world high jump silver medallist Yaroslava Mahuchikh posted another clearance of 2.00m which saw her finish well clear of compatriot Iryna Gerashchenko, who had a best of 1.93m.

Nia Ali, the 2019 world 100m hurdles champion, won in 12.61sec from home athlete Nadine Visser, who clocked 12.71.

Britain’s Reece Prescod won the men’s 100m final in 9.99 from Jamaica’s 2011 world champion Yohan Blake, who ran 10.05.
