American Tara Davis, a University of Texas student, wore cowboy boots on the podium after finishing second at the US trials. She made quite the entrance before the women's long jump final...

While the women's long jump final continues, on the track it's time for the men's 200m heats.

GB's Adam Gemili and Nethaneel Mitchell-Blake are among those aiming for a semi-final spot.

If you're starting to flag a little, maybe this will give you a second wind. We are just 30 minutes (or so) from watching Team GB's Deborah Kerr in the final - she's off at 03:37 BST.

Here's how she got there...

Time for Jazmin Sawyers to get her long jump final under way...

And her opening attempt is also met by a red flag.

So, after the first round in the women's long jump final it's Ese Brume in pole position.

A long way still to go, of course.

Things starting to hot up... 6.97m for Ese Brume, she goes into first place. It's all about finding a rhythm in these early rounds and Brume has done just that.

Decent jump form Irozuru but it's a red flag. Okay, it's a foul, but that bodes well because she is a long, long way down the pit...

The women's long jump final is under way, and it's Nigeria's Ese Brume in the lead with an opening leap of 6.97m.

Up next, it's GB's Abigail Irozuru...

It's a decent enough first jump but Irozuru steps over the mark and it's not going to count..

Team GB's 35 medals are now six ahead of the number our pre-Olympic Virtual Medal Table forecast had at this stage.

We have therefore adjusted our projected British medal total upwards to 58, including 16 gold medals as the number of golds is also two ahead of schedule.

At this stage, it looks like Great Britain should finish fourth on total medals, ahead of host nation Japan.

The current Gracenote forecast of 16 for Great Britain would almost certainly mean fifth place on the final medal table. Track cycling will probably be the key for this number to go higher to challenge the Russian Olympic Committee on golds.

When you can hop, step and jump the length of a London bus and some...

That is really, really tough. It looked strict as well, but those are the rules and we have to be honest.

As athletes, you have to be able to stay within your lane, it's something that athletes do week in, week out. It's so unfortunate that it's happened on the biggest stage for Nicole Yeargin.

It's heart-breaking stuff, but she'll learn from this.

We have got form in the women's long jump in Tokyo, well if you scroll back through the history books.

Mary Rand won gold almost 58 years ago at the 1964 Games.

Since then, Sheila Sherwood's silver (Mexico, 1968) and Sue Hearnshaw's bronze (Los Angeles, 1984) are Britain's only other medallists in the event.

George: Looking at the 3 British runners, we could be challenging for a medal in relay.

The big favourites going into women's long jump in Tokyo are the likes of USA's Brittney Reese who won London 2012 gold and silver in Rio five years ago.

Then there is the likes of current German world champion, Malaika Mihambo, Serbia's Ivana Spanovic who won bronze in Rio, Nigeria's Ese Brume and Reese's American team-mate Tara Davis.

All have jumped seven metres or more this season!

Great Britain's Abigail Irozuru reached the final after a season's best of 6.75m.

Irozuru, 31, was not selected for London 2012 and retired after she missed Rio in 2016 due to a ruptured Achilles.

She may have to go well beyond her current PB of 6.86m to get a medal in this..

Jazmin Sawyers finished 11th in qualifying and reckons she will improve today.

She is certainly a lady of many talents, having won a Winter Youth Olympics silver in bobsleigh and competed on the television singing competition The Voice.

The Commonwealth (2014) and European (2016) silver medallist will have to go some to get a medal here but she has been edging closer to the magical seven-metre mark and Shara Proctor’s British record of 7.07m, this season.

One of those would do nicely...followed by a tune.

It will soon be time for us to turn our attention to the sand pit for the women's long jump final, featuring Jasmin Sawyers and Abigail Irozuru.

So, that's GB pair Jodie Williams and Ama Pipi into the women's 400m semi-finals.

Earlier, Josh Kerr, Jake Wightman and Jake Heyward all safely progressed from their 1500m heats.

If you missed it, take a look at this.

Marileidy Paulino, is she one to now consider as a medal contender? This her first year - she's got better and better as the season's gone on. Still learning the event, but to great effect when she's got the 200m speed she has.

BBC One

GB's Nicole Yeargin, speaking before she knew she was disqualified: "A little bit of a weight off my shoulders, the first one down is always the most nerve-wracking so I'm ready for the second race.

"It's been good to be here! You could think, 'wow, it's the Olympics,' but once you start running it's a normal track meet."

The Dominican Republic's Marileidy Paulino is in her own postcode!

She eases off in the closing stages for a cool 50.06 lap. That was very, very impressive.

And Ama Pipi does make it through to the semi-finals following that final heat. Lovely stuff.

Ama Pipi will soon know if she's done enough. Here goes the final 400m heat...
