In case you missed it, Julien Alfred took victory in the women's 100m a little earlier on.

Britain's Dina Asher-Smith finished third - and she will return to the track in the 200m at 20:30 BST.

Karsten Warholm joins Femke Bol in setting a new meeting record in Zurich as the Norwegian continues to sharpen up before the World Championships.

The world record holder looks smooth and controlled as he crosses the line in 46.70 seconds.

Britain's Alastair Chalmers finishes seventh in 48.88.

Britain's Alastair Chalmers is involved in the men's 400m hurdles.

Karsten Warholm is the clear favourite for the title as the only man in tonight's line-up to run sub-47 seconds this year.

Germany’s Julian Weber leads the men’s javelin at the halfway stage after beating his personal best and breaking his own world leading distance not once, but twice.

Weber threw 91.37m in the first round to beat his world lead distance of 91.06m (set in May 2025) and followed it up with a throw of 91.51m.

Keshorn Walcott (Trinidad & Tobago) is second with 84.95m while reigning world champion Neeraj Chopra (India) is third (84.35m).

Never in doubt.

Femke Bol looks completely effortless as she glides over the barriers and takes victory in a new meeting record time of 52.18 seconds.

With Sydney McLaughlin-Levrone focusing on the 400m flat in Tokyo, Bol will be the red-hot favourite for world gold.

We're heading back for some more hurdles action now, with some stellar names taking to the track.

Dutch star Femke Bol is up first in the women's final, before Karsten Warholm contests the men's race.

Simbine is clocked at 9.98 and Blake at 9.99, with Jeremiah Azu crossing the line fourth in 10.03.

Time for the men's 100m now, and Britain's world indoor 60m champion Jeremiah Azu goes in this one.

It's already been a significant year for Azu. The 24-year-old has been crowned Welsh, British, European and world champion over 60m indoors in 2025, while he also became a father for the first time.

With a season's best over 100m of 9.97 seconds, he goes up against three athletes who have gone under 9.90 this year - including former world champion Christian Coleman and defending Diamond League champion Ackeem Blake.

Halfway through the women’s javelin and it’s Greece’s Elina Tzengko who’s in pole position.

The former European champion produced a best throw of 64.57m in the first round, with Serbia's Adriana Vilagos (62.96m) currently in second place and South Africa's Jo-Ane du Plessis (62.26m) in third.

Reigning Olympic, world, and Diamond League champion Haruka Kitaguchi (Japan) is in last place and yet to clear 60m.

There are three rounds remaining.

That's as comfortable a victory as you'll see this evening, as Kenya's Faith Cherotich wins the women's 3,000m steeplechase by more than 13 seconds.

One of only four athletes in history to run under 8:50 - and one of two to do so this season behind Winfred Yavi - Cherotich canters to victory in 8:57.24.

St Lucia's Olympic champion Julien Alfred storms clear of the competition over the second half of the race to take victory in 10.76 seconds and retain her title.

Dina Asher-Smith runs 10.94 for third, behind Jamaica's Tia Clayton.

Ah, a false start in the women's 100m!

It's Marie Josee Ta Lou-Smith in lane five who appears to go a fraction early - but following a bit of protesting after being shown a red card, she's allowed to run.

Dina Asher-Smith said she prioritised being in a "nice, friendly and focused environment" after taking the decision to move her training base back home to London just weeks before the World Championships.

The 2019 200m world champion had been based in the United States, training under coach Edrick Floreal whose group includes Olympic 100m champion Julien Alfred.

Asher-Smith is competing in both the 100m and 200m in Zurich, and comes up against St Lucia's Alfred in the former first - and that's up next.

"For me, I just had to be in an environment where I'm happy and I feel like I can build and work through races and race plans in a really focused way. I'm really happy to have done that. I just had to come home.

"It was just most important for me to be in a nice, friendly and focused environment. Just being able to run free and focus every day on how fast you can run from A to B."

Heartbreak for Yared Nuguse, who fades to seventh in the end, and that is one of the major medal contenders out of the men's 1500m in Tokyo - an event in which Great Britain will have two world champions in Josh Kerr and Jake Wightman.

Talented Dutch 20-year-old Niels Laros displays his devastating finishing speed to capture the Diamond League trophy and prize money in a national record three minutes 29.20 seconds. He will be a big threat next month.

Italy's Andy Diaz won the men's triple jump with a jump of 17.56m.

Portugal's Pedro Pichardo (17.47m) and Algeria's Yasser Mohammed Triki (17.42m) had set the pace with season's best jumps in round one before Diaz snatched the lead in the fourth round.

Diaz previously won the Diamond League crown in 2022 (representing Cuba) and 2023 and claimed bronze at the 2024 Olympics.

Over to the men's 1500m now.

And this is an absolutely huge race for American Yared Nuguse, with the Olympic bronze medallist's hopes of competing at the World Championships resting on victory here after he failed to qualify via the US trials.

The Diamond League winners receive a wildcard to the championships. Away we go...

Oh no, that is agonising for Jessica Hull!

The Australian's legs have completely gone as she struggles to hold on down the home straight, before she is pipped to victory on the line by Kenya's Nelly Chepchirchir.

Chepchirchir wins it in three minutes 56.99 seconds as Hull drops to the ground, utterly exhausted after finishing second in 3:57.02.

Ireland's Sarah Healy places eighth in 3:59.90.

Cuba’s Leyanis Perez has won the women’s triple jump title for the second year in a row.

The world indoor champion jumped 14.91m in Zurich – just two centimetres short of her season best.

Her compatriots Liadagmis Povea and Davisleydi Velazco completed a Cuban 1-2-3, with jumps of 14.72m and 14.65m respectively.
