STOCKHOLM — Olympic champion Lukas Martens of Germany has broken the men's 400-meter freestyle record at the Swim Open Stockholm.
Martens became the first swimmer to break the 3 minute, 40 seconds barrier, finishing Saturday's race with a time of 3:39.96.
That was 0.11 seconds better than the previous record set by fellow German Paul Biedermann in 2009, according to Olympics.com.
Biedermann's mark had been set wearing the drag-reducing ''super suits'' that were eventually banned in 2010.
The 23-year-old Martens won the 400-meter freestyle gold medal at the 2024 Paris Olympics with a time of 3:41.78.
