Think again.Almost 13 years after winning her first Olympic title, arguably the greatest swimmer in history has proven she is still getting better.The 28-year-old legend has tuned up for July's 2025 World Aquatics Championships in Singapore with a series of blistering swims in Florida this week, underlining her status as one of the all-time greats of the sport and setting down a marker to her rivals.Ledecky shattered her near-nine-year-old world record in the 800m freestyle by over half a second, swimming 8 minutes, 4.12 seconds at the Tyr Pro Swim Series in Fort Lauderdale.Katie Ledecky last broke the 800m world record at the Rio Olympics in 2016.

(Getty Images: Carmen Mandato)In doing so, she beat Canadian phenom — and likely successor to her crown as North America's biggest star — McIntosh to gold.With McIntosh turning under Titmus's world record pace at the 300m point and leading Ledecky by 0.85 seconds, the American powered home in the final 100 metres to claim victory.Loading Twitter content"I don't know if I ever thought I was gonna be [able to swim] a 3:56 again," an emotional Ledecky told NBC Sports.ABC Elite Athletes in Australian Women's Sport Survey: We want to hear from youPhoto shows A stylised graphic with three silhouettes of unidentified a female footballer, tennis player, basketballerABC Sport and Deakin University have partnered to produce the first ABC Elite Athletes in Australian Women’s Sport Survey."It just wasn't even in my head for tonight, for sure."Titmus's world record mark of 3:55.38 from the 2023 World Championships remains intact — for now.Ledecky had kicked off the meet with the second-fastest 1,500m freestyle time in history on Wednesday, swimming 15:24.51.She is also the two-time defending Olympic 1,500m champion and is the only woman to have ever won a gold in the event since its introduction in Tokyo in 2021.Ledecky has won five of the last six races over that distance at the World Championships, only missing out in 2019 when she withdrew due to illness.At the recent Australian Swimming Championships last month, Mo Johnson won the 1,500 metres freestyle in 16:02.59.It was not just Ledecky who was laying down markers in Florida.Gretchen Walsh twice broke the 100m butterfly world record, swimming 55.09 in the heats before smashing that time with a blistering 54.60 in the finals.Gretchen Walsh was quite surprised by her time in the 100m butterfly heats.
