That was 79.2 kilometres per hour from Matthew Richardson, that must be so scary to do on that track. A 45 degree bend it not enough, he's probably touching three Gs as well.

And just as Katie says that, Australia's Matthew Richardson has set a new world record time of 9.091 seconds. Incredible!

Israel's Mikhail Yakovlev has just set a new Olympic record of 9.152 seconds.

That is likely to be short-lived though. On this track, and with the world's very best still to come in qualifying, that record - and the world record - is likely to tumble further.

It's been incredible, a cracking start for Team GB in the cycling. We've already won a silver last night, guaranteed another silver at least. It's been an amazing start.

Emma Finucane could end the Olympics as one of the stars for Great Britain as she bids to becom a three-time gold medallist.

A world and Olympic champion at 21 hasn't shocked father Rory at all.

“I remember her first race,” recalls her father, Rory. “You could see then that she enjoyed it so much, it made her competitive. She put a lot of effort in and she was really keen.”

“She just enjoyed racing,” adds her mother, Susie. “She didn’t mind if the weather was bad. It was the speed too - she always liked to go fast.”

Her success? “You could see it coming,” her father added.

Great Britain's representative in a sport dominated by teenagers is 51-year-old Andy Macdonald, the oldest ever Olympic skateboarder.

The Massachusetts-born skateboarding legend qualifies for GB via his Luton-born father.

He's been a pro since 1994, was one of the early advocates for skateboarding as an Olympic sport and says he has probably created a lot of the skills that today's skateboarders perform.

His team-mates are younger than his son and he calls himself a 'Rad Dad'. He's in the fourth qualifying group so we will see him a bit later.

We have bad news from the golf, where things could not really be going much worse for Britain's Charley Hull.

She is seven-over par after just 12 holes, leaving her dead last on the leaderboard out of 60 competitors.

The only good news for Hull is that this is the opening round of four - plenty of time to make amends. Her team-mate Georgia Hall is one-under after three.

Jack Carlin is used to being on the podium, but he's also used to hearing other national anthems.

To his name he has three Olympic, five World Championship and six European medals - but none of them are gold.

In an era of Dutch dominance, it's Jeffrey Hoogland and Harrie Lavreysen who are the men to beat in the sprint. But how much pressure can Britain's Carlin put them under?

"Everyone's beatable," Carlin told BBC Sport Scotland. "Even the best make mistakes.

"We've all gone out early in competitions, we've all made silly moves that cause us to fall off.

"It's just part and parcel of being a track sprinter because it's so demanding.

"Basically, you have to race a single person each time. There's no hiding."

Katy Marchant is the first to take to track in the women's keirin heats for Great Britain as she looks to add to the gold medal already captured in Paris.

The 31-year-old starts her bid for gold at 12:26 BST with Emma Finucane coming at 12:47 BST.

Hamish Turnbull's average speed there was 77.38 kmh - that's almost 50mph.

Just to put it into perspective how quick these guys go. Tres rapide.

As soon as they get into their flow you need as little fidgeting as possible. It needs to be power, very still and aerodynamics.

For a big guy Hamish Turnbull gets very small on the bike.

Great Britain's Hamish Turnbull has powered into the lead with a new fastest time of 9.346 and he is through to the next round!

Hamish Turnbull was "buzzing" after winning Olympic team sprint silver at his debut Games last night.

Wonder if he's come down off cloud nine yet, or whether that adrenaline will give him added firepower on the boards today?

When he was just 14, he became the youngest rider in history to claim a British national track sprint title.

That record was previously held by some guys you might have heard of.

Sir Jason Kenny and Sir Chris Hoy.

As well as the skateboarding, this venue is going to be hosting the Olympics’ newest sport, breaking, later this week.

To get everyone in the mood, they’ve brought a flavour of breaking to the pre-competition show and around the grounds they’ve got breakdancing shows on.

The 30 riders go one at a time in a bid to post a time that puts them inside the top 24 after completing three-and-a-half laps.

Great Britain's Hamish Turnbull is eighth to go while Jack Carlin is the 28th rider to put a time in.

We'll let you know how both get on!

There’s a reason they call Alexsandra Miroslaw the Spiderwoman of Lublin. The world champion is through to the last four.

It’s hard to get across how quickly these athletes climb this 15m wall.

It’s about twice the size of your standard semi-detached house in the UK or three London buses stacked on top of each other but is scaled in less than seven seconds.

Wild.

We're about to get underway with the men's skateboarding park preliminaries.... this is the one in the concrete bowl rather than the street one that has the rails.

it's a simple format - there are 22 skaters and they are divided into four groups. Each skater does three 45-second runs.

Five judges use a scale of 0.00-100.00 to judge each of the runs. The highest and lowest scores are dropped, with the remaining three averaged (to two decimal places) to give an overall score.

The top eight qualify for the final.

On the Red Button, and iPlayer (and the Watch and Listen tab on this page), it's skateboarding time. Great Britain's Andrew Macdonald, who celebrated his 51st birthday (yes, 51st) last Wednesday, is taking part in the men's park prelims.

We're about to get under way in the Velodrome with men's sprint qualifying first on the agenda.

Great Britain's Hamish Turnbull and Jack Carlin are looking to progress.

After that, we'll have GB's Emma Finucane and Katy Marchant in the women's keirin heats.
