Three-time Olympic champion Adam Peaty made a first step towards a fourth Games in Los Angeles by winning the 100m breaststroke at the Aquatics GB Swimming Championships in London.

Peaty, 31, was challenged by two teenagers, Filip Nowacki and Max Morgan, but came through to win in 58.97 seconds.

Nowacki was second in 59.39, with Morgan third in a huge personal best of 59.56.

Peaty and Nowacki confirmed their places on the GB team heading to Paris for this summer’s European Aquatics Championships with their results.

Peaty’s time was the second best in the world this year, external, suggesting that his time at the top could continue yet as he targets the 2028 Olympics.

“We’ve got some talented youngsters coming through the pool,” he said.

“I’m not talking about this year, it’s about LA for me, and these boys are going to challenge me the whole way.”

It is almost a year since Peaty, who got married while swimming took a back seat, confirmed he will go again.

He made the decision after it was confirmed the 50m breaststroke event would be added to the schedule in 2028. It gives Peaty a second shot at more individual golds – the chance to add the 50m title to the 100m medals he won in 2016 and 2021.

British titles will be awarded in 36 medal events across the meet in London this week.

Other winners on Tuesday night included James Guy in the 400m, Imogen Clark in the 50m breaststroke and Eva Okaro in the 100m free.
