Three-time Olympic champion Adam Peaty took bronze in the men’s 100m breaststroke at the World Championships from 2019.
The 29-year-old Briton was fastest in the final in Doha with a time of 58.60 seconds but swam 59.10 in Monday’s competition.
Peaty is using the event as he prepares to take a third consecutive Olympic 100m gold in Paris this summer.
“Now is how we can prepare for the Olympics,” Peaty said.
“I think I did my best in the 50m, but it’s good to run against the best players in the world and it’s good to be there – well done to these guys it’s not an easy race.”
The world record holder finished behind American Nic Fink (58.57) – who led from start to finish – and Italy’s Nicolo Martinenghi (58.84) to claim his 11th world medal.
Peaty became the first British swimmer to retain an Olympic title when he took gold in the 100m at the 2021 Tokyo Games.
He missed the 2022 World Cup with a foot injury and was unavailable last year after taking a break from the sport to focus on his health, but told BBC Sport last week he was in good shape ahead of the worlds in Doha.
Peaty is looking to return to the top of the podium at this summer’s Games in the French capital to add to his three Olympic golds, eight world titles, 17 European titles and four Commonwealth Games golds.
‘Peaty in a good place’ – Adlington
Two-time Olympic gold medalist Rebecca Adlington said she believes Peaty will be “surprised” by winning a medal and will soon return to focus on her Olympic return.
“Adam is in a good place,” he told BBC Radio 5 Live Breakfast.
“They’re not going to get better because they don’t want to do well now, they want to do well in the summer. They want to be on that Olympic team.
“So I think he’s in a really good position to do that. And I think he surprised himself by getting back on the field.”
Adlington is confident there is enough talent in the British team to help chase down Peaty and defend a “few medals” in Paris.
“Obviously Adam realizes he’s the game guy,” he added. “We’ve got some medal winners, you’ve got people like Matt Richards, Tom Dean and Duncan Scott, but Adam is a name everyone knows.
“I feel like people are just following him because they want to see him doing well, not to watch him closely, but just to see him doing well.
“The other guys are amazing swimmers and they deserve more credit than they get because what they’ve achieved in this sport is fantastic.
“If it wasn’t for Adam Peaty, it would be the boys. We have a great team. I think we are good.”
Fellow Briton James Wilby missed the final after pulling out of the race on Sunday.
Meanwhile, GB’s Abbie Wood missed out on a medal in the women’s 200m medley final, finishing sixth in two minutes 11.20 seconds.
