"It's a huge surprise," says Sir Chris Hoy of the Italians' stunning victory.

No wonder the winning riders are covering hands with mouths and thumping their chests with fists as they contemplate their achievement.

Joyous scenes when the Italians dismount and join their support staff in a celebratory huddle.

"Campiones, campiones, ole, ole, ole...!"

Surely not another world record time? There could be you know. The Italians have a narrow lead at the halfway stage - but back come the Danes...

Next up? New world record holders Italy take on favourites Denmark for the gold medal. Can the Azzurri's golden summer continue?

Oh no! A heck of a crash in the men's team pursuit bronze-medal race as one of the New Zealand riders falls. Fingers crossed he is OK.

The Kiwis were heading for a super-quick time, too. Looks like an overlapping of wheels was the cause.

That gives the bronze medal to Australia. Fine lines...

ICYMI... Britain's reign as Olympic champions came to a controversial end during Tuesday's semi-final with Denmark.

Hopes of a fourth straight gold ended with a bizarre crash caused by Danish rider Frederik Madsen, who reacted angrily despite being at fault.

Thankfully GB's Charlie Tanfield wasn't seriously hurt and rode again today.

Back to the velodrome then where Great Britain take part in the men's team pursuit.

Following yesterday’s painful defeat – literally following that crash – by Denmark, the three-time reigning champions race the Swiss for seventh place.

The British team of Charlie Tanfield, Ethan Hayter, Ethan Vernon and Oliver Wood put that behind them to cross the line in a rapid three minutes 45.636 seconds.

It's enough to beat the Swiss but only enough to claim seventh place at Tokyo 2020.

Great work from Shauna Coxsey but Iuliia Kaplina is in pieces - a disaster for the world record holder. Like her life's work has all been undone on one foothold.

One down in the women's combined, two to go. Here are the standings after the speed event:

1. Aleksandra Miroslaw (Pol) 6.97

2. Anouck Jaubert (Fra) 7.12

3. Yiling Song (Chi) 7.46

4. Miho Nonaka (Jpn) 7.55

5. Iuliia Kaplina (Roc) 7.65

6. Allannah Yip (Can) 7.99

As we just told you, Britain's Shauna Coxsey is 16th after a dash of 9.65 seconds to the top of the 15m wall. Iuliia Kaplina is fifth, despite falling in her second climb.

Graham Hill: Gotta love the wall climbing

Rich Gartland: Speed climbing is bonkers

Evil Batman: I have a grappling hook , so I cheat

This climbing is brilliant! Like a much better version of The Wall on Gladiators. Another 90s reference there for the kids...

After moving over to Lane A, Britain's Shauna Coxsey has produced a slightly faster time up the 15m wall.

She the hit buzzer in 9.65 seconds but she actually drops one place into 16th.

We'll be moving on to the bouldering and the lead disciplines next...

Coxsey will need to pull out the stops to ensure a top eight finish, and qualification for the final.

Excellent ride by Katy Marchant in the repechage.

Very different ride from Marchant this time, waiting at the back to go, and physically was able to dominate.

And she dealt with the pressure really well after having been relegated.

If at first you don't succeed.

Well in Katy Marchant's case she sort of did, winning her heat and then being disqualified.

No issues in the repechage though as the Brit storms round the outside to advance.

Think I was largely busy trying to recreate Tony Yeboah's wonder goal for Leeds United in the front garden. Never managed it.

Cracked next door's kitchen window instead. Ooops.

But most of us have done that. Sure your stories are more interesting...

Sky Brown has won an Olympic medal aged just 13 years and 28 days!

The momentous bronze makes her Great Britain's youngest Olympic medallist.

But what were YOU doing at 13? Were you out playing heads and volleys against your neighbours hedge? Or maybe you were finally allowed to get your ears pierced? Or perhaps you were hammering the buttons on Tony Hawk Pro Skater dreaming of achieving what Sky Brown has managed in Tokyo.

Adam Peaty has spoken, but we want to hear from you. Get in touch on #bbcolympics

Only just joining us? *shocked face emoji*

Where have you been? OK, you've been sleeping and then getting ready for work. Fair enough.

Here's a rundown of what you've missed so far on day 12...

• Skateboarding: Sky Brown becomes Great Britain's youngest Olympic medallist of all time, with the 13-year-old winning bronze in the women's park skateboarding.
• Hockey: Great Britain will not retain their Olympic women's hockey title after being well beaten by the Netherlands in the semi-finals.
• Athletics: USA's Sydney McLaughlin smashes her own world record with a sensational run to take gold in the women's 400m hurdles.
• Athletics: Britain's Katarina Johnson-Thompson sits third overall after two events in heptathlon.
• Sailing: Hannah Mills and Eilidh McIntyre clinch gold in the 470 class, making Mills the most successful female Olympic sailor of all-time.
• Boxing: Ben Whittaker continues Team GB's impressive boxing campaign with a men's light-heavyweight silver medal after Frazer Clarke takes bronze in the men's super-heavyweight division.

Shauna Coxsey's Olympic campaign is under way, but it hasn't quite gone to plan for the Great Britain climber so far.

She managed a time of 10.07 seconds in her first attempt in the speed discipline in the women's combined event.

That opening run in Lane B currently has her down in 15th place.

Two-time defending champion Jason Kenny won silver in the team sprint on Tuesday to take his Olympic tally up to a record-equalling eight.

Today he has eased through in the men's sprint - watch below how he did it...
