The noise has just been cranked up to cover your ears level, as Leon Marchand has walks out into the arena.

Duncan Scott and Tom Dean are ready to fight the Frenchman for a medal...

I didn't think it was possible but that might be the loudest cheer for Marchand's entrance all week.

There is a lot of commotion among the photographers opposite me. They have their lenses all pointing into the stand above.

It's French president Emmanuel Macron here to see Leon Marchand.

The British women, Honey Osrin and Katie Shanahan could not replicate the form from the semi-finals.

Shanahan finishes fifth and Osrin in seventh. Great effort from the two GB swimmers.

Kye Whyte has been taken from the course on a stretcher. You really don't like to see that. This is a brutal, brutal sport and it's the fourth crash we've seen tonight.

The Tokyo silver medalist had been struggling with a back injury which he said was aggravated last night after his three quarter-final runs. He didn't start well in that second run.

Let's hope that Whyte is OK, we wish him a speedy recovery.

That is a thing of beauty. Ben Proud, the humble British swimmer has delivered for years and years and he was just missing that medal and he's done in a quality time as well, just missing out on the gold.

Ben Proud was born in London but grew up in Malaysia and then he did his building I suppose in Plymouth college and then moved to Turkey and has been training over there.

And as he's gotten older his training has gotten smarter and he's done more land training and less pool training.

All the training he does in the pool is about the most beautiful of technique. You watch these guys and you think it's just power and splash but inside of that they're looking to be absolutely perfect and hydrodynamic through the water.

No time to rest. GB cheers are needed again, as Honey Osrin and Katie Shanahan are lining up for the final of the women's 200m backstroke.

Keep your eyes on lanes one and three.

Ah that is lovely. He came for gold but a medal for Ben Proud couldn't be more deserved. He gives a big thumbs up to the British in the crowd.

He had won a medal at the worlds, Europeans and Commonwealths. Now he has that Olympic medal.

France's Florent Manaudou, meanwhile, is making the absolute most of this atmosphere. And it's just for bronze.

The gap between Cameron McEvoy in first and Ben Proud in the silver medal position?

0.05 seconds.

So close.

Oh no. This doesn't look good for Great Britain's Kye Whyte.

He crashes after the first set of ramps in the second of his semi-final runs and it's a heck of a tumble he takes.

The medics are out, the stretcher is out.

Let's hope this is not as serious as it looks.

We go from trampolining to BMX racing on BBC iPlayer.

That's the beauty of the Olympics.

There's British interest in both the men's and women's events, with Kye Whyte and Beth Shriever both trying for medals.

A brilliant swim from Cam McEvoy we wondered if he could calm the nerves and he has delivered.

Ben Proud has got his medal, it's not a gold but he has got to be happy.

Ben Proud takes the silver medal!

It wasn't the gold, but that Olympic treasure is finally ready to add to his collection.

Australian Cameron McEvoy just pips Proud to the 50m title, with Florent Manaudou of France taking the bronze.

Frenchman Florent Manaudou is conducting the crowd before an Olympic final!

Ready?

For me Ben Proud's career deserves a medal. He is one of the best starters.

Here comes our guy. Great Britain's Ben Proud is aiming for that first Olympic medal.

Bang! Bang! Bang! The stick tells us it's about to be a stellar night in the pool.

Florent Manaudou comes out to huge applause for the men's 50m freestyle final. The home fans want to see some magic from the Frenchman.

The first race of the night is the men's 50m freestyle final, also known as the Splash and Dash.

It will crown the fastest man in the world across one length and Great Britain have a great medal chance.

Ben Proud is one of the most popular and admired members of the GB squad. He has won World Championship, Commonwealth and European gold but never a medal at the big chance.

Is this his night?
