Perhaps the best chance of seeing a world record today comes in the Emsley Carr Mile at 15:36 BST.

Olympic silver medallist and former world champion Josh Kerr, 28, is aiming to add his name to the stellar list of British men to have held the world record for the mile.

The 2023 world 1500m champion announced in March that his intention was to break Moroccan Hicham El Guerrouj's time of three minutes 43.13 seconds set in 1999, when Kerr was just a year old.

Kerr set his personal best of 3:45.34 in 2024 and is sixth on the all-time list, two places behind Olympic 1500m bronze medallist Yared Nuguse of the United States, who also races on Saturday.

Kerr, who won world indoor 3,000m gold in Poland earlier this year, will be paced by his training partner Brannon Kidder and will have fellow Scot Neil Gourley alongside him.

The Scot has been fitted with a bespoke aerodynamic suit and custom spikes for the attempt - and believes the odds are in his favour despite needing to take 2.21 seconds off his personal best.

"As an athlete, I'm not scared of failing," he said. "It's not something that I was born with. I'm on the attack at all times and I'm bold with what I talk about."

Today's world record hopes rest on the shoulders of Josh Kerr then...

(Unless Keely Hodgkinson surprises even herself and produces something special.)

Former women's marathon world record holder on BBC One

A perfectly judged race by Brandon Miller. He sat back enough and stayed in contact enough but not such much that he overcooked it. The change of pace he had coming in was immense.

Ireland's Mark English finished well as he always does but he and rest were trailing the wake of Brandon Miller.

He won the Los Angeles gold meet and he looked absolutely superb when he won that. This is next race and that is another massive jump forward.

What a run from Brandon Miller of the US!

With Emmanuel Wanyonyi fading, the American flies through to win in a personal best time of 1:42.19.

Ireland's Mark English finishes strong as well and comes through for second. It's a personal best for him as well, 1:42.97.

Britain's Max Burgin pips Wanyonyi to third with another Briton Ben Pattison fifth in a season's best time.

This is not a record run at the moment...Emmanuel Wanyonyi looks spent.

The world record is slipping away from Emmanuel Wanyonyi...

Emmanuel Wanyonyi has settled in behind the pace maker with Britain's Max Burgin right on his shoulder at the bell.

Here we go...

And they're off!

Is Emmanuel Wanyonyi less than two minutes from history?

Speaking of that potential world record, the men's 800m is up next.

Emmanuel Wanyonyi has history on his mind.

Less than five minutes until that one gets under way.

Britons Ben Pattison and Max Burgin are also in this one. They'll have eyes on the British record.

Interestingly, it seems that the wave lights - an LED pacing system installed along the inside curb of athletics tracks - is being set for world record attempts in the men's mile and the men's 800m.

Josh Kerr and Kenya's Emmanuel Wanyonyi are planning to make it a day to remember then.

However, the women's 800m is being set at British record pace so perhaps we might have temper expectations for Keely Hodgkinson.

Then again, it's just a guide so let's not rule anything out, either!

Marileidy Paulino momentarily looked in a bit of trouble as they came round the final bend.

But we should no better than to doubt her.

She reels in Jamaica's Nickisha Price, who went out very fast before fading, and takes it in 48.97 - around half a second outside the world lead.

Norway's Henriette Jaeger is second in 49.15, a national record, Stacey Ann Williams of Jamaica in third.

GB pair Yemi Mary John and Charlotte Henrich were seventh and eighth, respectively, but there was a PB for Henrich.

Next up on the track it's the women's 400m...

Marileidy Paulino from the Dominican Republic, the Olympic and former world champion, goes out as the big favourite.

Earlier today, British teenager Divine Iheme smashed the men's 100m record in winning gold at the European Athletics U18 Championships.

Iheme, 16, ran 10.29 seconds in the final to cross the line seven-tenths of a second ahead of the rest of his rivals.

The world under-18 men's 100m record stands at 10.00 secs, set by Japan's Sorato Shimizu last year.

"I knew I was going to get [the win], but I thought ‘I’ve still got to just go crazy," Iheme said.

"I just gave it my all, and God helped me do it. It feels amazing. A championship record, a gold medal, and first place is all you can ask for."

Karsten Warholm with a statement performance!

The former Olympic champion powers to victory ahead of a top-class field in a world leading time of 46.61 seconds.

Excellent from the Norwegian.

Germany's Emil Agyekum is second in 47.45 - that's a new national record - with Qatar's Abderrahman Samba third in 48.10.

The Diamond League action is about to get under way on the track and first up it's the men's 400m hurdles.

We have got official word on the women's 4x100m... and the handover was legal!

It means victory in a season's best time for the Great Britain team.

A relay double for the Brits.

Still waiting for the official outcome from that women's 4x100m relay but a quick update from the men's pole vault.

Sweden's Armand Duplantis has limbered up and cleared 5.60m at the first attempt. No surprise there.

Great Britain's Owen Heard also got over first time and the bar has been raised to 5.75m.

Great Britain cross the line first - and by a distance - but it's a late first change that could be the issue.

Dina Asher-Smith was handing the baton over to Amy Hunt and it was close to the end of the zone... was it too late?

Season's best of 42.06 if it stands.

Ireland were disqualified for a false start, will the first GB team be DQ'd as well?
