Four-time Olympic gold medallist athlete on BBC TV
The gold medal is back with the USA. Richardson has been showing her potential and now she's got it. When she got going it was unbelievable. The frequency was unmatched. No pressure and she was able to get it done.
Steve Cram
Marathon commentator on BBC TV
This time Richardson got out quick and she was charging. She is the world champion!

Women's 100m final

Dina Asher-Smith always seems to deliver on the big occasions - but that was a real scare in the previous round.
She faces fierce competition as she aims for a fourth individual world medal, but despite concerns she may have picked up an injury she is here and waiting in the tunnel.
Just look at the start list. The six fastest women in the world this year are all here. Ranked sixth in 2023, it’s going to be exceptionally tough for Asher-Smith to make the podium.
But, as she said before these championships, major finals are not run on paper – and nor are they won in the semi-finals.
Women's 100m final
Dina is bouncing up and down in the waiting room, settling my nerves over a potential injury a little at least.

But who would bet against the legend that is Shelly-Ann Fraser-Pryce?

I thought Shericka Jackson was the most impressive in the semi-finals.

Now for the women's 100m final.
What has Dina Asher-Smith got in the tank after an untidy semi-final?
Can she get in amongst the big favourites - five-time champion Shelly-Ann Fraser-Pryce, American Sha'Carri Richardson and Shericka Jackson - the fastest woman in the world this year.
Men's 110m hurdles final

Grant Holloway is showing everyone three fingers.
His rivals, the crowd, the TV cameras. THREE successive men's 110m hurdles titles.
The American beats his chest. Utter domination.
The Jamaica supporters to our left are also enjoying themselves following Hansle Parchment's silver.
Colin Jackson
Two-time world 110m hurdles champion on BBC TV
Holloway destroyed the field over the first three hurdles and if you manage to do that then you establish the rhythm of the race.

It's a hat-trick for Holloway!
"One-two-three!" he roars to the crowd after a storming win.

Men's 110m hurdles final
Before that women's 100m we have the small matter of the men's 110m hurdles final.
The contenders have just emerged into the arena.
American Grant Holloway is going for a third world championship title in a row.
Hansle Parchment, who beat him in the Olympic final, is in lane eight.
Women's 100m final
Harry Poole
BBC Sport in Budapest
As if the women's 100m final couldn't get any better, it does look as though we're going to have nine athletes contesting the medals - assuming all is well with Dina Asher-Smith.
Ewa Swoboda, knocked out of the second of two non-automatic qualifying spots by one thousandth of a second by the Briton, appears to have been allowed to progress, with the officials taking up the option of using all nine lanes available on the track.
Men's discuss final
We've had some drama in the men's discuss final.
Slovenian Kristjan Ceh, the 2022 world champion, looked to have snatched victory with the penultimate effort of the competition with 70.02m which took him ahead of Olympic champion Daniel Stahl.
But then with the last throw of the dice Swede Stahl produces a championship record of 71.46m before standing expressionless with his arms wide.
A stunning competition.
