Ouch. KJT is getting some treatment on a tight hamstring which would leave most of us mere mortals limping around for a week.

"Nothing to worry about," says Denise Lewis, a former queen of the heptathlon.

We'll take her word for it.

It's almost KJT time!

World champion Katarina Johnson-Thompson made a mixed start to her heptathlon campaign and she sits third after two events.

The British athlete is back in action later with the shot put and 200m.

If you missed it earlier, here's her impressive 100m hurdles victory.

How it started....

How it's going

Job done for Elaine Thompson-Herah who confirmed her place among the sprinting greats on Tuesday as she secured a women's 100m-200m double-double with victory over the longer distance in Tokyo.

The Jamaican athlete, who posted her goals on Instagram, says her account was suspended for two days for posting video of her victory in an apparent breach of broadcasting rights.

"Highly effective."

I'd take that as a review for this live text.

Nicely done Jason Kenny - so well done.

You can lay off and try and give somewhere to accelerate or do the opposite - get on the wheel and stay out of sight so he can't see you. Then as soon as you make a move they haven't got anywhere to move and you can accelerate away.

That's what Kenny did he just took Yuta Wakimoto by surprise.

Highly effective.

So that means both British riders in the men's sprint are safely through to the 1/8 finals. The losers of these races have another chance, though, going into the repechage.

No such stress for Carlin and Kenny. They can head to the recovery room and rest before tomorrow's next stage.

Well, that was closer than anticipated! Yuta Wakimoto makes a late dash for the line, but Jason Kenny has enough of an advantage to cross first.

Kenny, who is aiming to win an outright British record NINTH Olympic medal, wins by 0.021 seconds.

Jason Kenny is the two-time defending champion and has got going in the final heat against Japan's Yuta Wakimoto. The eight-time Olympic medallist picks his moment to whizz past his opponent about halfway round. A sneak attack by Jason...

Jack Carlin was already inside the sprinters line so he's not at fault - amazing he stayed upright. At 70kph coming off the track you're in danger of touching your inside pedal off the ground. It wasn't intentional - his bodyweight had shifted to the point where he couldn't correct.

Both riders stayed upright and the result stands.

Team GB's Jack Carlin has gone through to the 1/16 finals in the men's sprint - Jason Kenny is looking to join him in a moment or two...

Olympic boxer Ben Whittaker said before competing in the final that one of his non-sporting goals was to become mayor of his hometown Wolverhampton.

Speaking to 5 Live’s Naga Munchetty, current mayor for Wolverhampton, Greg Brackenridge, says he is working to make those dreams come true for Ben.

“He will be mayor for the day”, he said. “I can guarantee you now, he will be given the red carpet treatment and he’ll get the hero’s welcome he deserves.”

Ben Whittaker won Great Britain's second boxing silver of Tokyo 2020 after defeat by Cuba's Arlen Lopez in the light-heavyweight gold-medal bout.

Whittaker, 24, was left in tears on the podium after losing on a split decision to the classy Lopez.

Earlier on Wednesday, Frazer Clarke won bronze in the men's super-heavyweight class after losing his semi-final to Uzbekistan's Bakhodir Jalolov.

Team GB have won a record six medals in the boxing events at Tokyo 2020.

But a disappointed Whittaker said he felt like "a failure" after being unable to win gold. Watch his emotional post-bout interview below...

There was disappointment for Great Britain in the women's hockey semi-finals as the defending champions were beaten 5-1 by the Netherlands.

They go for bronze on Friday against Argentina or India.

The Sky is the Limit. Touch the Sky. Ribbon in the Sky. Anymore for anymore?

Never mind bright blue, Sky is BRONZE.

British skateboarder Sky Brown broke down in tears after becoming Great Britain's youngest Olympic medal winner of all time.

Aged 13 years and 28 days, Brown produced a composed final run to finish third in the women's park skateboarding final and claim bronze at the Tokyo Games.

"It was a super sick final," she told BBC Sport.

As always, there has been plenty going on in Tokyo today. Medals and records all over the place.

Watch what you've missed in the video below...

While we wait to see Jason Kenny return to the track (in about 10 minutes or so), let's have a little catch up...

Carlin makes his move on the second lap, with a few 'ooohs' as he wobbles on his way past. The Brit keeps upright and maintains his advantage to cross the line first.

Will the result stand? Or was there an illegal (albeit unintentional) interference? Nope, the result stands.

Carlin finishes 0.132 seconds ahead to progress.

Three laps, first past the line. The winner of each heat qualifies for the 1/8 finals. Got it?

Both men have recorded good times so far. They're off... Jack Carlin skulks after his Malaysian opponent...

The action in the velodrome does not stop there. Oh no.

We're straight in the men's sprint where British pair Jack Carlin and Jason Kenny go in their respective 1/16 finals.

Carlin faces Malaysia's Muhammad Shah Firdaus Massahrom in the third race, with Kenny facing Japan's Yuta Wakimoto at 10:34 BST.

As per the previous ride it was Filippo Ganna who brought it home, the secret weapon and the ingredient they needed.

Denmark, a phenomenal team who have had a controversial tournament but Italy were closing down in that last minute and they had enough track to go the distance.
