No one better than Steve Cram to call this one, given he broke this world record himself back in 1985.

Three minutes and 43.13 seconds is the time to beat to break a world record that has stood since 1999...

Colin Jackson
Two-time world 110m hurdles champion on BBC OneRai Benjamin is a hurdler but he looks capable running over this distance. He's used to having the pressure of people breathing down his neck. He'll have learned how to balance himself for this event.
That will be a big victory for Benjamin given there's all these 400m runners around him. Hurdlers sometimes don't have the timing and rhythm for the event.

Hurdler Rai Benjamin of the US takes it ahead of Matt Hudson-Smith of Great Britain!
Benjamin led throughout and had enough to stop Hudson-Smith and another American Jacory Patterson from getting past on the final straight.
A personal best of 44.05 for Benjamin. Hudson-Smith clocks 44.18, 0.09 outside his season's best.

We're getting ever closer to Josh Kerr's world record attempt in the mile.
But first, the men's 400m with Matt Hudson-Smith hoping to provide a British victory...

Two-time world and Olympic javelin silver medallist on BBC OneArmand Duplantis might have withdrawn from the pole vault while the event was ongoing but that should take nothing away from Sam Kendricks' performance today.
Kendricks wins men's pole vaultpublished at 15:24 BST
Nobody can go clear at 6.04m and so Sam Kendricks of the USA takes the win.
He had been perfect up to 5.95m and Mondo Duplantis' withdrawal means no one can get past him.
Duplantis also cleared 5.95m but had one failure at 5.85m.
Burgin 'lacking sharpness' after Achilles issuepublished at 15:21 BST
Men's 800m
Max Burgin, speaking after finishing third in the men's 800m: "I wasn't lacking in fitness, I think I was just lacking in sharpness.
"I had taken the month off with an Achilles problem after Rabat, so I have had quite a bit of bike work building up to this one which was a bit unfortunate.
"Hopefully, by the time we are at the championships in a few weeks time, the sharpness will be there."

BBC athletics commentatorThat was a good race by Julien Alfred. It was all about the first 50m for me and Alfred stayed strong once she had the advantage.

Two-time world 110m hurdles champion on BBC OneJulien Alfred drove out so hard and in the first 20 or 30 metres she stepped up like she was running 100m.
Gabby Thomas pushed on but Alfred powered her way to the finish line. She has a big smile because she is relieved to get another 200m under her belt.

A superb start saw the Saint Lucian pretty much level with Thomas on the bend and then she has more than enough in the tank to ease clear.
Bahamas' Shaunae Miller-Uibo in third and Dina Asher-Smith edging out Amy Hunt for fourth, both ran season's bests.
