Australia’s Titmus smashes Ledecky’s 400m freestyle world record

Olympic gold medalist Ariarne Titmus has broken the women’s 400-metre freestyle world record at the Australian swimming championships.

Titmus finished in 3 minutes, 56.40 seconds in Sunday night’s final at the South Australian Aquatic Centre to improve on Katie Ledecky's previous mark of 3:56.46 that the American set at the 2016 Rio Olympics.

“It’s kind of nice now that I am not going to be asked when I am going to break the world record,” Titmus said. “I am the happiest I have ever been outside of swimming, I am the happiest I have ever been in my life in swimming. It’s definitely showing in the pool.”

Titmus beat Ledecky for Olympic gold in the 400 and 200 and finished behind the American star in the 800-metre freestyle final at Tokyo last year.

“I am definitely not putting the pressure on myself that I used to but it’s still a healthy amount,” the 21-year-old Titmus said.

“That has been the trick to me swimming well. Just going out there completely fearless, swimming what I used to feel like when I was 16 and first cracked on to the national team and just going there and surprising myself.”
