The women's hockey semi-final between the Netherlands and Great Britain has just got under way.

It's a repeat of the Rio 2016 final, which saw GB win in a dramatic penalty shootout.

You can watch it live on the Red Button.

Jane: Sky Brown, what can I say? She reaches for the sky! Amazing! I'm in bed in a hotel, watching on my phone. Need to sleep but am gripped!

Jonathan: Oh man, that was one epic run from Sky Brown, it’s very Tony Hawk-esque!

Ryan: Sky Brown though! Cool as a cucumber, amazing run no wonder she's always grinning.

While Sky Brown is looking a dead cert for the final sadly Bombette Martin is out as her score is no longer among the top eight.

Regardless, an incredible moment to be the first Olympian to compete in this event.

So many tricks from Sky Brown that we haven't seen from anyone else.

She hasn't even stretched her legs on that run. Big, big cheers from the crowd.

Phenomenal first run from Sky Brown, she goes straight over to Bombette Martin and hugs her.

It's 55.26! Best score so far. Phenomenal run by Sky Brown.

Huge applause as Sky Brown completes her run. It looked pretty much faultless to me, nailing a Japan Air one of the highlights.

Now we wait for the score...

Here we go, the debut of the long-awaited Sky Brown at the Olympics.

She is the real deal. A year ago, she would have been a 12-year-old skater and a novelty, but in the year that's gone past she has added power, speed and a phenomenal amount of trick to her repertoire.

Back to the skateboarding and we are onto the third heat with Team GB's skateboarding star Sky Brown up in this one.

Chloe: So I’ve just worked out that if Melissa Williams is 36 & competing in the skateboarding, then Sky Brown could compete in 7 Olympic Games by the time she’s the same age.

Damian Warner is putting down a marker in the men's decathlon. After running the fastest time in the 100m he jumps a superb 8.24 in the long jump - that would have been good enough for bronze in that event at this Olympics.

The women's heptathlon 100m hurdle heats are done with USA's Kendell Williams running the fastest time of all with 12.97 seconds. That gives her a score of 1129 heading into the high jump.

Katarina Johnson-Thompson is seventh after the first event.

GB's Bombette Martin on BBC One: "I thought I was going to be really nervous, this morning I was really nervous, but earlier today I started landing all my runs. Then I was the first one! That was amazing, it will always be such an honour that I was that person. I landed my first run, I was happy with it.

"I'm definitely looking forward to Paris 2024. I'm going to have much higher standards in Paris, this was a good lead-in without the crowds, it was a good first Olympic experience.

"Skateboarding has deserved this, it's been a long time coming. It has such a wide viewership that it deserves something like the Olympics to really show what it is.

Ten skateboarders have done their runs and and 10 to go. Here's how things stand. The top eight go through to the final.

Two heats done in the women's park skateboarding heats and Sky Brown is up in the third.

Here's a bit more about the 13-year-old Team GB skating star.

Alice Dearing gave an emotional interview after completing the 10km marathon swimming open water event in Tokyo this morning.

She finished 19th in a time of two hours, five minutes and 3.2 seconds, which was five minutes and 30.4 seconds behind the winner Ana Marcela Cunha from Brazil.

However, by taking to the water she became the first black woman to represent Great Britain in an Olympic swimming event.

“I really hope it makes a difference and people look at this (me) and think it’s possible for anyone out there. It’s tough, it’s hard but if you want to learn to swim 25m or go to swim in the Olympics I want people to know that it’s open and available to everybody and just go and give it your best shot.”

"It’s only three years until Paris I’ve got a lot more to give and learn, this is my first Olympics, I’m definitely not done. I’ll go home, take my time get over it and then come back stronger next year and the year after.”

Adam: In a time where we are debating women's kits for sport more and more, I do love how you can show up to the skateboarding in a patterned boiler suit and that's cool.

Ten skaters to go and only eight can advance and Bombette Martin is right on the bubble with the eighth best score as we approach the end of heat two.

There could be more skateboarding success for hosts Japan as Kokona Hiraki scores 52.46 - the first in the heats to score above 50.

The men's decathlon heats are under way with Damian Warner running the 100m in heat three in 10.12 seconds, equaling the record he himself set in 2019.
