Jakob Ingebrigtsen had been out for 324 days, but he knew he was going to win from 600m out.

The Norwegian star announced his comeback from injury by winning the European 5,000m title in Birmingham this month.

And then wasted no time in reigniting his rivalry with Great Britain's Josh Kerr.

After the 25-year-old won a record-equalling seventh European Championship gold, Ingebrigtsen told BBC Sport he was "very" disappointed by Kerr's decision not to compete at the championships, claiming that athletes who choose to miss major competitions are "ruining" the sport.

Tonight, Ingebrigtsen races over 1500m against a stacked field featuring Olympic medallists Cole Hocker and Yared Nuguse, and world champion Isaac Nader.

GB's Jake Hayward is also in this one. Away they go!

All eyes are on Armand Duplantis as he composes himself.

This is where he thrives.

But he catches the bar. Not as good as his first attempt. Has he got the energy for one more go?

Greece's Emmanouil Karalis has one more shot to come.

Armand Duplantis returns to the runway, ready for another attempt at a world record 6.32 metres.

All the world record talk in the build-up to Zurich was around the women's 800m.

We are about 20 minutes away from that. Don't go anywhere!

The men's pole vault world record can definitely go here too!

Both Armand Duplantis and Emmanouil Karalis are locked in and attempting 6.32m.

Duplantis currently leads the competition with his clearance over 6.25m. Two more attempts to come for both athletes.

In case you missed it, or simply want to enjoy it again, here's that world record run by Brazil's Alison dos Santos.

Emmanuel Wanyonyi is desperately trying to hang on to the world record pace as the second pacemaker drops out.

It's not going to be, but it is a world-leading one minute 41.76 seconds for Kenya's Olympic and world champion, who is pushed all the way by Djamel Sedjati.

GB's Jake Wightman crosses the line in fourth in a time of 1:43.76.

It is not only the eagerly anticipated women's 800m which could see a world record come under threat this evening.

Kenya's Olympic and world champion Emmanuel Wanyonyi, the second-fastest man over the distance of all time, has also been speaking about the possibility of making history sometime soon.

His compatriot David Rudisha's record time of one minute 40.91 seconds has stood since the London 2012 Olympics. Wanyonyi's personal best is just two tenths of a second shy of that mark.

He is joined in tonight's race by the fifth and sixth fastest men in history, in Algerian Djamel Sedjati and Frenchman Gabriel Tual.

Away they go...

Not long ago, Brazil's Alison dos Santos broke the 400m hurdles world record with a stunning run of 45.80 seconds.

Look at those celebrations!

We have the men's pole vault continuing, and nearing record heights, and now possibly the first of two world record attempts over 800m this evening...

Anything you can do...

Armand Duplantis responds to Emmanouil Karalis' personal best clearance at 6.20m by jumping 6.25m.

The Swedish superstar looks really up for this. I'm getting more world record vibes here...

On the track, Uganda's Peruth Chemutai and and Kenya's Faith Cherotich, the fastest two athletes in the world this year, are locked in battle on the final lap.

Kenyan Doris Lemngole is the only other athlete who can stick with them, but it's Cherotich who finishes the strongest to win in eight minutes 55.82 seconds.

GB's Thorner places fifth in 9:11.41.

After winning her first senior international medal, with silver at the Commonwealth Games, Elise Thorner lined up for the European Championships with high expectations.

The 25-year-old entered as - and remains - the fastest European woman this year in her event, but just missed out on the podium in Birmingham, finishing fifth.

But it has nonetheless been a season of significant improvement for Thorner, who has lowered her personal best by almost nine seconds to 9:05.45 - leaving her just over a second off Lizzie Bird's British record of nine minutes 04.35 seconds.

Uganda's Peruth Chemutai and and Kenya's Faith Cherotich, the fastest two athletes in the world this year with sub-8:52 clockings.

The full European podium is also present, in Germans Gesa Felicitas Krause and Olivia Gurth, and France's Alice Finot.

And we're only just getting warmed up in Zurich, too.

The action continues to come thick and fast...

It has not quite been business as usual - that being total domination - for Armand Duplantis in 2026.

The Swedish pole vault star, naturally, improved his world record to 6.31 metres earlier this year.

But he also saw his 40-event winning streak unexpectedly ended on home soil in June.

The 26-year-old got married this summer, while he has also been working on the official song for next month's World Ultimate Championships.

Having said he remains keen to break his record again before the end of the season, he has safely cleared 5.90m so far this evening.
