It's so good to see Shaunae Miller-Uibo smile and her run in this 200m was very encouraging. She should be excited to run in the final. It's looking like a very exciting final and I cannot wait.

The Ivory Coast's Marie-Josee Ta Lou wins the third semi-final in a season's best 22.11 seconds.

The Bahamas' Shaunae Miller-Uibo also goes through to the final in 22.14.

Now for some maths to see if Switzerland's Mujinga Kambundji is fast enough to be in the final with 22.26...

In 2004 the IOC permitted transgender athletes to take part in the Olympics.

Since 2015 athletes who have transitioned from male to female can compete in women's sport - without requiring surgery - as long as they have declared their gender identity is female for at least four years and kept their testosterone below a set level.

Three other openly transgender athletes were selected for Tokyo 2020.

Footballer Quinn is playing for Canada’s women’s team. Skateboarder Alana Smith competed last week. BMX cyclist Chelsea Wolfe was a reserve athlete who did not appear.

What Elaine Thompson-Herah did there was kill the bend which is one of the benefits of the outside lane. That propelled her into a position where she didn't have to attack the line. We might see something really special in the final. Elaine has already shown she is a class above. I don't know what Shelly-Ann Fraser-Pryce will be thinking when he sees that!

Another Jamaican win in the 200m semi-finals.

Defending champion Elaine Thompson-Herah basically jogs over the line as she qualifies first in the second semi-final in a lightning-quick 21.66 seconds, equalling her personal best.

The most interesting result is second place where Namibian 18-year-old Christine Mboma gets the better of American Gabrielle Thomas. Mboma's 21.97 is a new junior world record.

Thomas may well go through as a fastest loser with 22.01.

Great Britain's Beth Dobbin finishes fifth with 22.85.

Since the earlier athletics session, we've seen the USA's Jade Carey win gold in the women's floor final, with GB's 16-year-old twins Jessica and Jennifer Gadirova finishing outside the medals...

Oliver Townend then secured team eventing gold, giving GB their first medal of the day...

Laurel Hubbard's selection has sparked debate. The New Zealand Olympics committee says Hubbard is a “really important role model” who “opens up a conversation about inclusivity”, while some of her fellow competitors have welcomed the move.

However critics, including some athletes, have questioned her inclusion. A key aspect has been around whether Hubbard carries an advantage due to going through male puberty.

Many of the scientists and academics cannot agree on this point.

Great Britain's Beth Dobbin is in the next one...

The nice thing about Shelly-Ann Fraser-Pryce's run was that she was not that aggressive. I think she can go under 22 seconds. She wasn't challenged too much in that semi-final but you do want to do enough to show you are here to win a medal. Coming into the semis you just want to get a good lane for the final to run in.

Women's 100m silver medallist Shelly-Ann Fraser-Pryce wins the first semi-final in 22.13 seconds.

Namibia's Beatrice Masilingi qualifies alongside the Jamaican with a personal best of 22.40, while the Bahamas' Anthonique Strachan and Australia's Riley Day will have to wait and see if their 22.56 is good enough for a fastest loser spot.

The first two from each of the three semi-finals will qualify automatically for the final, with the two next fastest across the three races going through as well.

Coming up in around 20 minutes is the women's +87kg weightlifting.

Britain's Emily Campbell is involved. She is the current European champion and won bronze at the 2018 Commonwealth Games.

New Zealand's Laurel Hubbard is also in action, as she becomes the first openly transgender athlete to compete in a different gender category to that which they were born at an Olympic Games.

There was good news for a couple of Brits on the track earlier, though. Here's what's happened so far on day 10 in the athletics:

• British pair Laura Muir and Katie Snowden safely progressed to the semi-finals of the women's 1500m, while world champion Sifan Hassan recovered from a fall to win her heat
• Beth Dobbin is into the women's 200m semi-finals after finishing second in her heat, ahead of Jamaica's Elaine Thompson-Herah, but 100m bronze medallist Shericka Jackson has missed out
• Briton Nick Miller has made the hammer final
• Greece's Miltiadis Tentoglou prevailed in a dramatic final round of the men's long jump final, claiming gold with his final leap
• Jasmine Camacho-Quinn won Puerto Rico's first ever track and field gold in the women's 100m hurdles final

First up, we have the semi-finals of the women's 200m.

Of course there is sadly no Dina Asher-Smith in this one after the Briton revealed she tore her hamstring earlier this month and would have to pull out of the event.

And here is that fall by the Netherlands' Sifan Hassan earlier in her 1500m heat.

Still came back to win it though. Good effort!!

Right then, we'll return to the equestrian later. In the meantime we've got another three gold medals to be decided on the track and in the field shortly.

The women's discus, men's 3,000m steeplechase and women's 5,000m titles are up for grabs in this session.

Two-time Olympic champion Sandra Perkovic of Croatia is one of two track and field athletes looking to secure a third consecutive Olympic title in Tokyo while Kenyan athletes are expected to feature prominently in the steeplechase.

But in the 5,000m, Sifan Hassan goes for the first part of what she hopes will be a treble in Tokyo. It's been a busy day for the Dutchwoman, who earlier had a dramatic heat in the 1500m, falling at the start of the final lap but still managing to win after overhauling the field in a stunning final 350m.

Those rounds also leave the British trio well placed for the individual medals later on.

Oliver Townend's one fault on that last round saw him slip to second in the individual standings, with Tom McEwen third and Laura Collett fifth before the final round of jumping to decide those medals at 12:45 BST.

That is Great Britain's first team eventing gold in 49 years.

A great effort from world number one Oliver Townend, Laura Collett and Tom McEwen, who are all making their Olympic debut.

Great Britain went into the competition as one of the favourites along with Germany. But the Germans have had a disaster and are nowhere near the medals. GB won nothing at Rio 2016 but this time it's a gold medal.

Great Britain have a commanding lead in the team event, and now Oliver Townend is the last to go on Ballaghmor Class.

It will take several faults to deny Great Britain gold.
