Adam Peaty twice lowered his own 50m breaststroke world record as he became the first man to swim inside 26 seconds and Emily Seebohm won bronze in the 100m backstroke on a thrilling night at the World Championships in Budapest.
Ruta Meilutyte was fourth in the 100m breaststroke and Mitch Larkin came sixth in the men’s 100m backstroke at the Duna Arena as the third day concluded by the River Danube.
Adam already has one gold medal to his name this week after winning the 100m breaststroke in the second fastest time in history.
The Briton then looked on as Cameron van der Burgh became the second fastest man ever in the 50m in the morning prelims – his time of 26.54 an African record – only for Adam to lower his own world record of 26.42 to 26.10.
He returned in the evening to crack the 26-second mark in 25.95, smoke coming off the water as he left his rivals in his slipstream.
And all with the final to come on Wednesday evening.
He beamed: “I was on such a massive high from the morning and it was so hard to ignore the fact that I did a world record in the morning and try to get myself emotionally ready, but I’ve learned from the experiences I’ve had over the last two, three years.
“I didn’t think I was going to do that. I thought I was going to go slower because I was a little bit less energetic. But tomorrow’s the day to do it, really. We’ll see what we get.”
The 22-year-old believes there is still more to come, saying: “Oh yes, 100%. Everyone says they work at 10/10, but everyone works at 9/10 and you’ve got to find that extra 10/10 to take that step further.”
Emily won the 100m and 200m backstroke double at the last World Championships in Kazan, Russia, in 2015.
The Australian finished outside the medals at the Olympics in Rio de Janeiro last year but she came in to Budapest on the back of a fine Mare Nostrum tour.
She was second at halfway before being touched out by 0.01secs in 58.59 to make a return to the podium after her Olympic woe.
It was Emily’s best time of the season and she said: “I am so proud to be back on the podium! I could be better if I had not got a cold, but I am very happy!
“I am here to swim to do my job and the colour of the medal does not matter.”
Ruta has had to make a lot of changes in the past year, importantly switching coach after former guru Jon Rudd left Plymouth where they both enjoyed success to take up a performance head role in Ireland.
The Lithuanian won Olympic gold in 2012 and was second in Kazan and although she was just pipped to a medal on Tuesday night, her time of 1:05.65 after a 1:05.06 in the semis underlined her world-class pedigree.
Like his sweetheart Emily, Mitch also won the 100m/200m backstroke double in Kazan two years ago.
On Tuesday he finished sixth in the shorter event in 53.24.
