Great Britain’s Adam Peaty set a World Championship record as he successfully defended his men’s 100m breaststroke title in Budapest at the 2017 FINA world swimming championship.
The 22-year-old Olympic champion, who had lowered the World Championship mark in qualifying, clocked 57.47 seconds – 0.34secs outside his own world record.
Peaty told BBC Sport: “You aim for world records, but they are world records for a reason.”
Fellow Briton Ben Proud, 22, took the 50m butterfly title, clocking 22.75.
Peaty, who now holds the top 10 times in the world for the 100m breaststroke, finished more than a second ahead of his nearest rival.
That was American Kevin Cordes (58.79), with Russia’s Kirill Prigoda (59.05) third. Peaty’s fellow Briton Ross Murdoch was eighth.
“I felt like a little boy again going out to the crowd,” said Peaty.
“I was a bit long into the wall, but I’m very happy with that. I’m more than happy to come here and attack my title.”
Peaty is attempting to become the first swimmer to break the 57-second mark in the event, a challenge he refers to as ‘Project 56’.
The Briton, who in 2015 became the first man to complete the world 50m and 100m breaststroke double, will begin the defence of his 50m title on Tuesday.
