2019 World Para Swimming Championships - London
Here's how it all went down on Day 1. All times local to London (British Summer Time/BST)
We cornered the U.S. swim star and forced her to answer our questions in London.
Which she did - in the nicest way possible!
In the first women's race of the day the Ukraine's Yelzyaveta Mereshko looked certain to win gold in the 400m freestyle S6, but was stunned by China's Jiang Yuyan by beating the favourite and setting a new world record.
Poetic justice then that in the very last race of Day 1 Mereshko should grab that gold medal after all.
It came in the Women's 100m Breaststroke SB5 Final where Mereshko was determined not to be denied again.
Here were the final times:
Searing pace in the Men's 100m Breaststroke SB5 Final!
Russia's Andrei Granichka takes gold and breaks the world record.
China's Li Junsheng swam under the previous world record too and forced Granichka to go even faster.
This race had stars and stripes painted all over it right from the beginning.
Serious speed from the USA's Evan Austin as he takes the S7 butterfly splash and dash.
This was a stacked race, one of the fastest races at the entire event.
Austin was fastest in the splash and dash, with Colombia's Carlos Serrano 0.01 of a second behind the Ukraine's Yevhenii Bohodaiko.
A first gold medal for the mejicanos as Arnulfo Castorena wins the Men's 50m Breaststroke SB2 event.
It's silver for Australia and bronze goes to Greece.
Here's how it finished:
It's a silver medal for Grant 'Scooter' Patterson, one of the personalities of the Games.
Aurelie Rivard tells Olympic Channel her secret: "I pretend the cheering is for me even though I know it's for the two British girls."
Classic positive visualisation, or audiolisation? From the Canadian champion.
Meyers is beaming and well she should be.
The U.S. swimmer has just set a new world record in the Women's 400m Freestyle S13 Final.
Belarus' Ihar Boki has a lot to live up to with everything he's won and done in Paralympic swimming.
And he just keeps coming up with the goods.
Another gold for the most successful of all the precious metal collectors here in London in the men's 400m freestyle S13 event.
Boki's lead just continued to grow as he stroked his way relentlessly to the board.
Tell us what it feels like to win gold at the Worlds Tully Kearney.
Don't hold back now.
No world record, but a supreme swim from Canada's Rivard.
Britain's strong finisher Zara Mulloly did what she does and secured silver, bronze went to the Netherlands.
Another enthralling 50m race, so close, could have been anyone in a group of six swimmers.
But Italian Stefano Raimondi has the golden touch.
He could hardly believe it himself that it was all cameras on him poolside!
More home joy in the Women's 50m Freestyle S5 Final, her reaction said it all.
A super swim from Kearney.
Silver goes to Suzana Hext who looked to be on her way to an Olympic career in equestrianism until an accident in 2012 changed her life, now she's making the podium at international swimming events.
It's a delightful return to British waters for Brazil's Midas man.
6 gold medals and 4 world records at London 2012, he's just won the men's 50m freestyle S5 final.
France's Franceso Bocciardo dived in and used the underwater to take an early lead but Brazil's Dias clawed it back and took down an American record.
Rivard has world record in her sights.
Russia's Anna Krivshina takes it!
Bronze for Brazil and silver goes to Spain.
More joy for the Ukraine as Yaroslav Denysenko swims a phenomenal 100m.
He's 5 hundredths of a second outside the world record that was set here at London 2012.
The men's 100m backstroke S12 swimmers walk on to one of the greatest club anthems ever recorded.
'Insomnia' by Faithless.
Some of the best music in the world for some of the best swimmers in the world.
Paralympic great Sophie Pascoe wins yet another Worlds gold medal - her 13th - in the Women's 100m Freestyle S9 Final.
It was clear from an early stage that no-one was going to get close, she was racing the world record but didn't not quite
Toni Shaw makes the podium with a personal best, great result for the young swimmer.
Here's how it finished:
The future looks bright for Toni Shaw.
'Like London buses' says the commentator.
That's our third world record tonight, Barlaam set his stall out early and finished so so strongly.
Lots of Italians in the crowd, how they enjoyed that.
Can anyone stop Italy's smiling assassin Simone Barlaam?
Fter a great start Barlaam a couple of lengths ahead after 50.
Stroking his way to the finish.
And it's another world record!
The Ukraine have brought a stacked squad to London and it's paying dividends.
The one-length dash is pipped by Maryna Piddubna after yet another photo finish.
Belarmino Pereira is fastest in the splash and dash, he had a good Lima Parapans and he's got off to a flyer in London.
Gold goes to Russia!
Valeriia Shabalina isn't going to be caught here, an imperious swim, chased down by four British swimmers.
GB's Louise Fiddes touched home in fourth.
With such a scintillating start, there hasn't been any time for Shazam.
No music pumping while the swimmers are racing as we have in some other events - Lima 2019 for example.
But we do have a live commentator and plenty of tunes pumping to keep the blood flowing between races.
Sigala and Ella Eyre's 'I came here for love', another Sigala number in 'Give Me Your Love' ft. John Newman, Nile Rodgers, and the Yeah Yeah Yeah's ultimate dance classic 'Heads Will Roll'.
Keep 'em coming DJ.
What a start to the World Championships we're having here.
It's a world record and an all-British podium at a home Games.
Men's 200m Freestyle S14 Results:
The crowd is going wild here.
What a swim from Alice Tai who powers home unstoppably.
Tai is just a tenth of a second outside world record pace, she didn't get out of the heat in Rio, but a move from Manchester to London and a new club has pressed reset on her swim career.
Smiling again, loving swimming again, Tai has proved that she's world class here and deserves to be on top of the podium.
Here's how it finished:
Greece's Michalentzkis clinches a real nail biter.
A photo finish that gives us tied bronze medallists!
That was so close.
A first world title for Hungary's Fanni Illes, silver for Giulia Ghiretti from Italy, bronze for Chinese swimmer Cheng Jiao who topples an Asian record..
Catch your breath!
A world record and a massive shock in the second race of the night gives way to the men's 100m breaststroke final.
A European record!
Not a bad riposte.
Jiang Yuyan has pulled out a massive shock here by not only beating the favourite and reigning Paralympic champ Yelyzaveta Mereshko, but by breaking her world record too!
No-one saw that coming.
Maisie Summer-Newton finishes just off the podium in fourth place.
Jiang Yuyan is leading the Paralympic champion, this would be a huge upset.
Ellie Simmonds in third.
With all the swimmers lined up they've been stopped by the officials.
The sound box is the problem, someone's having a fiddle with the wires.
And they're in the water, it's on.
A varied start in the S6 category.
Strong start from the favourite, Mereshko leading the way, China's Yuyan Jiang at the leader's feet in second.
This is close to world record pace for the Ukraine, can she beat her own mark?
In the women's 400m freestyle S6, the world record holder Yelyzaveta Mereshko from the Ukraine finished first in this qualifier, swimming 5:23.52.
Mereshko will have to bring her A Game in the final with China's Yuyan Jiang breathing down her neck - she was a second and a half off in heats - clocking 5:24.92.
Don't count out home hero Ellie Simmonds either.
All her experience will have told her to ease into it and swim a solid race in the heat, her 5:26.23 still guaranteed her one of the middle lanes and she has the crowd right behind her.
What a ruckus for Ellie Simmonds!
Big cheer for Maisie Summer-Newton too, the two British racers.
He was never going to be caught, opening up a big lead after 200m, Granichka is second.
A strong start from the Dutch swimmer but Granichka and Fantin reel him in, it's Fantin opening up a big lead here.
The Italian flags are flying!
This looks like a straight race between Russia's Andrei Granichka and Italian swim sensation Antonio Fantin, who were 10 seconds faster than everyone else in the heats.
Fantin took Dublin by storm winning four gold and two silver medals at the 2018 Euros and has world records in his sights in London.
But it was Granichka who swam the fastest 400m this morning, 5:13.19 to Fantin's 5:14.70.
Who'll come out on top?
No, not the music, the stadium - it's packed.
Great atmosphere already in here, we're about 10 minutes from the first event and the maiden medal of London 2019.
Here's another classic, the Clash's 'London Calling' - one of the most emblematic songs ever to come out of the capital.
The crowd love it!
President of IPC Andrew Parsons makes his address:
"With Tokyo 2020 on the horizon, your time to shine is now."
The Paralympic anthem sounds out as the Paralympic flag is raised.
The athletes parade is underway here, flagbearers waving their nations emblem proudly.
The buzz is building, excitement mounting, queues forming in an orderly fashion.
With such a strong legacy in swimming, Australia is always strong at international swimming events.
Makes sense too - island nation, warm weather, lots of water.
They have good support too!
We're about 15 minutes away from the official Opening Ceremony here in London.
Paralympics GB are getting a little teary remembering London 2012.
What a spectacular show it was.
The future of Ugandan swimming was in action today: 12-year-old Husna Kukundakwe swam in the Women's 100m Freestyle S9 Heat 1 finishing 7th
Kukundakwe dreams of making the Tokyo 2020 Paralympics, and would become only the second Ugandan ever to reach the Paralympic Games after Prossy Tusabe at the Sydney Games in 2000.
Her hero is Katie Ledecky and London 2019 is a huge opportunity for her to grow and learn.
“She’s my role model. She started competing when she was very young, she was young and she was breaking records. I get the motivation to continue because I’m also very young and I want to be like Katie Ledecky,” the Ugandan swimmer said.
With her improved backstroke and increased coaching hours before London 2019, Kukundakwe could make that Tokyo 2020 dream come true.
The butterfly and breaststroke heats bring the morning session to a close.
USA's Evan Austin is the fastest man in the 50m butterfly S7 heats clocking 30.07, while Ukraine's Yevhenii Bohodaiko kept pace in 30.32 and watch out for Colombia's Paralympic great Carlos Serrano, he finished in 30.38.
The two fastest women in the 50m butterfly S7 are Italy's Giulia Terzi (35.81) and U.S. swimmer Mallory Weggeman who edged it in 35.54.
Spain's Antoni Ponce Bertran and Andrei Granichka secured their final lanes as fastest in the men's 100m breaststroke SB5.
And the final race of the day saw Ukrainian champion Yelyzaveta Mereshko assert her authority.
Mereshko is defending four titles from Glasgow 2015, but the women's 100m Breaststroke SB5 isn't one of them.
Make sure you watch this Paralympic star in the final later.
All the finals will be live streamed on Olympic Channel, we'll be online around 20 minutes before the races start at 6pm local time.
Tune in and keep one tab locked on the live blog for all the latest too!
Things started and ended well on the Day 1 morning session for Team USA.
Earlier star U.S. Paralympic swimmer Jessica Long topped her 100m freestyle S8 heat, Long took silver at Glasgow 2015 behind Australian Madison Elliott, this year she'll have to get past Alice Tai.
Becca Meyers, Evan Austin, and Mallory Weggeman all topped their heats too, putting themselves in the medal lanes for this evening's finals.
Long almost pulled out of the Worlds due to pressure of organising a wedding, but luckily for us she's here!
Looks like one of her bridesmaids is too!
Marked out early as one to watch here in London, Ihar Boki has lived up to his reputation already on Day 1.
Boki streaked ahead right off the blocks in the men's 400m freestyle S13 heat 1, then he just kept going.
The Belorussian finished this qualifier a whopping 17.77 seconds ahead of nearest competitor Dimitry Horlin from Uzbekistan.
Can anyone catch Ihar Boki?
Brazil's top collector of precious metals knows these waters well - 6 of his 14 Paralympic gold medals came here at London 2012.
Dias is the most decorated Paralympic swimmer at London 2019 with 24 gongs to his name overall, and he's begun in champion formm here.
Dias topped the men's 50m freestyle S5 heat 2 clocking 32.54, more than a second ahead of Italy's Francesco Bocciardo.
Muhammad Nur Syaiful Zulkafly took the other heat in 33.20 - a new Asian record.
Dias is fresh from a history-making showing at the Lima 2019 Parapan American games where he won his 31st gold medal in the continental competition.
When he's in the water, record tremble, expect nothing less in London.
There's a decently sized crowd for a Monday morning creating an enjoyable atmosphere in the stadium here, and the home favourites are delivering for their fans.
Alice Tai, Bethany Firth, Jessica Applegate, Toni Shaw, Tully Kearney, and Suzanna Hext, have all topped their heats and Ellie Simmonds, Maisie Summers-Newton cruised into their finals too meaning that home fans will have plenty to cheer later this evening.
That 200m freestyle S14 looks like it's going to be a special one for the host nation!
Malaysia's Muhammad Nur Syaiful Zulkafly has set a new Asian record in the men's 50m freestyle S5 heat 1.
His 33.20 sets a new continental mark.
The first swim for New Zealand's multiple Paralympic medallist is a good one.
Pascoe swims 1:01.20 in her women's 100m freestyle, the fastest qualifier by a stretch.
Closest was GB's Toni Shaw who won heat 1 recording 1:03.24.
We've just had three great heats in the men's 100m freestyle S9.
First Spain's Mari Alcaraz tops heat 1 with a time of 57.44, then Australia's Timothy Disken topped the second heat with 57.37 after a really close race and a photo finish, France's young gun Ugo Didier finished 3rd.
Then Italy's star-in-the-making Simone Barlaam who at just 18 won four gold medals in the last European Championships put down the fastest time so far.
54.99 makes him quickest qualifier and in with a chance to fell a world record later this evening.
Don't miss it!
Italy's double Paralympic medallist and 4-time Worlds set out a marker in the women's 100m breaststroke SB4 Heat 1.
This is going to be another fiercely fought final later this evening, Hungary's Fanni Illes aced heat 2 in 1:47.32 setting the fastest time.
Heat 2 finished:
We've had one of the most recognised names and faces in British swimming in the pool already too.
Ellie Simmonds is through to her first final in the women's 400m freestyle S6, finishing 3rd in heat 1, swimming 5:26.23.

This final is going to be a thriller, catch it later live on Olympic Channel at 6:36pm - set that reminder!

Here we go!
Here's the live stream on the official site, this might be available in your area too:
Day 1 showcases three of the biggest swimmers in the competition: Daniel Dias, Ellie Simmonds, and Ihar Boki.
Brazil swimmer Dias is the most decorated Paralympian at London 2019 with 14 gold medals at three different Paralympic Games.
He's Brazil's most successful Paralympian of all time with 24 Paralympic medals overall, and also owns 30 World Championships medals - 24 of them gold.
The effervescent swim star is fresh out of the pool from the Lima 2019 Parapan American Games where he added another three gold medals to the loot.
Look out for Dias in the S5 class, he'll be in the 50m heats starting just after 12pm today.
Find out more about Daniel here:
No introductions necessary. Get ready for home hero Ellie Simmonds to bring the house down today, the much-loved swim superstar will be out to prove to London that she's still in a league of her own.
Ellie won two gold medals at Beijing 2008 when she was just 13 and became the face of the London 2012 Paralympics when she bagged two more.
With the London Worlds this year and the Tokyo Games next year, Simmonds may need to buy a bigger safe to keep all the precious metal.
“London 2012 was an incredible experience," said Simmonds in the run up to London 2019.
"To represent my country on home soil was something I’ll never forget so to get the chance to do it all over again at the 2019 World Para Swimming Championships is pretty special."
Look out for Britain's para swimming poster girl on the morning of Day 1 in the 400m Freestyle S6 heat scheduled for 10:16am and the final in the evening session at 6:11pm.
You'll recognise her from the roar the crowd makes when they announce her name.
London holds happy memories for Bulgaria's Ihar Boki, he left the 2012 Games with five gold and one silver medal in the men’s S13 class.
The 25-year-old vision impaired swimmer topped the podium six times at the most recent World Championships in Mexico City in 2017 and while he hasn't been on top form of late, he almost always raises his game at the big events.
Boki will be in the pool in the S13 400m freestyle heats today scheduled for 12:24pm.
Mexico's Gustavo Sanchez is another one to watch.
