You know what? It has been far too long since we had a British Paralympian receiving their gold medal.

Good job we've now got Ollie Hynd having his turn on the top step. As the flag raises, he is singing along to the national anthem with the medal swinging around his neck. A wave, a huge smile.

That is his second Paralympic gold medal after victory in the SM8 200m individual medley four years ago. And he is only 21 so plenty of time for many more medals.

American Tatyana McFadden could have a sensational fortnight in Rio.

She won three golds in London 2012 and is aiming for more than double that in Brazil. Seven, in fact.

Originally born in Russia, McFadden was adopted by American parents and has been a keen sportswoman since her college days in Chicago. 

McFadden received world wide acclaim when she became the first athlete to complete a marathon grand slam (London, New York, Chicago, Boston) in 2013. 

And she won five world titles on the track in Lyon that year so to claim seven gold medals across all distances in Rio would be her biggest achievement to date.

The IPC say that at the last count they had sold 1.7 million tickets for the Rio Paralympics. Organisers are now just 300,000 short of their revised target of two million.

Only a brief interview with Stephanie Millward following her women's S8 400m freestyle third-place. 

The 34-year-old has MS and is rushed off for standard her post-race medical treatment shortly.

But she did manage to speak with Kate Grey and said: "A bronze medal is a great achievement and I'm loving the pool, it's really fast.

"It's a new set of experiences being in a new category with a whole load of new competitors but it's really exciting."

Here's a breakdown of what all the letters and numbers mean in the athletics arena. 

Athletes are given the letter T or F. T is for Track and F is for field. 

This is followed by a number for their impairment group e.g. a T44 athlete like Jonnie Peacock is a group that represents the loss of a lower limb.

Sammi Kinghorn is moments away from lining up in her first Paralympic final, six years after her whole world changed. 

Kinghorn, 20, was left paralysed when a block of ice fell onto her from the roof of her house when she was just 14. 

But Sammi has always been a fighter and after six months of rehab, she was keen to get into sport. 

Having found a love for wheelchair racing at 18, the 2014 European champion now lines up against China's Lisha Huang, who set a new world record of 16.20 in the women's T53 100m fina

BBC Radio 5 Live

Jonnie Peacock has been catching up with BBC Radio 5 live after breaking his Paralympic record in the T44 100m heats to move into tomorrow's final.

He said: "I'm reasonably confident for tomorrow. I got woken up at 7am this morning for a drugs test so hopefully that doesn't happen tomorrow."

Peacock will be in the T44 100m final tomorrow night at 23:58 BST. Definitely one worth staying up for.

That really was an emotional silver medal success for GB's Harriet Lee. It's her first Paralympic medal and comes after such a difficult five years.

Lee, 25, has Beckwith-Wiedemann syndrome, external and that has seen her succumb to a series of medical problems.

"It's been such a hard time in my life," she says between tears.

"My family and friends have kept me fighting through it and I'm so so happy with silver - it makes all the sacrifices make it worth it."

Harriet Lee, speaking to Channel 4: "I had my own race and stuck to it. To swim that race and time I'm so happy. 

"Four years has been a difficult wait but I've had some great support. There's a whole network of people behind me and I'm so thankful to them."

David Wood: "Excellent performance so far very well done."

Lucas Austin: "Brilliant from both Dame Sarah Storey and Crystal Lane."

So that's four golds, two silvers and one bronze for Great Britain in just over an hour and a half of action.

And as I'm writing that Dame Sarah Storey is up to collect her record-breaking 12th Paralympic gold medal - as she has become the most successful female British Paralympian ever.

She has the biggest smile in Rio. Being on the top of the podium is not an unusual feeling for her and an experience she first achieved in 1992. And now, 24 years on, she is still celebrating.

A wave to her friends and family in the crowd and a chance to hear the national anthem played. Special. Unforgettable.

The total in London 2012, was 34 golds, 43 silvers and 43 bronze medals. Can GB do even better this year?

It has been an amazing evening of action so far.

Great Britain are competing in 19 of the 23 sports and we know that Paralympics GB will only send a team if they think they have a chance of winning.

No stone is left unturned and speaking to people around the team, not just in cycling, they have a very good feeling we could better the medal haul from London 2012.

Meanwhile, in the athletics...

Britain's Kyron Duke looks to be struggling with his knee and elbow heavily strapped up. 

He recorded a throw of 11.41 to move him into fifth place out of seven athletes in the men's F41 shot put after three rounds. 

The Welshman didn't look happy as his third throw was ruled as a foul. He has three more chances to get himself a medal

A battling performance from Harriet Lee in lane one and she just squeaks home to get silver.

The 25-year-old from Huntingdon says he would miss her two dogs while she was away in Rio and was planning to speak to them via her laptop - well she does so with a silver medal around her neck now.

Dutch teenager Lisa Kruger is the standout performer as claims the gold medal.

Anyone fancy some more British medals?

You may be in luck...

Lets hear from another British medallist, and this time it is Stephanie Millward, who took bronze in the women's S8 400m freestyle.

She competed in the S9 category in London 2012 and is getting used to her new competition.

She told BBC Radio 5 live: "Everyone is swimming really well in a really fast pool. It's been exciting because I've got a whole new set of competitors.

"I've got a few more races and I'm really excited for them."

There may well be some more tears in the eyes of family members of Steve Bate and Adam Duggleby as the pair have just gone up to collect their gold medals. There won't be a dry eye in the house soon.

It can be an emotional business following these Paralympians, whether they are swimmers or cyclists or athletes.

The Bate and Duggleby fan club have tears in their eyes after Steve and Adam claim Britain’s third gold medal of the day in the men’s B 4000m individual pursuit.

This is a relatively new tandem pairing but they have blitzed their rivals here, just missing out on a second world record in the final and they also have a good medal chance in the road time trial later in the programme.

As well as a reward for all the hard work the riders have put in, it’s vindication of Steve and wife Caroline’s decision to relocate from Scotland where they had been based, to be nearer the National Cycling Centre in Manchester in order for Steve to chase his Paralympic dream.
