WOMEN’S 800 FREESTYLE – FINALS

• World Record: 8:04.79 – Katie Ledecky, USA (2016)
• World Junior Record: 8:11.00 – Katie Ledecky, USA (2014)
• American Record: 8:04.79 – Katie Ledecky, USA (2016)
• U.S. Open Record: 8:04.79 – Katie Ledecky, USA (2016)
• Pro Swim Series Record: 8:06.68 – Katie Ledecky (2016)

TOP 8:

1. Katie Ledecky (GSC) – 8:04.12 (World Record)
2. Jillian Cox (TXLA) – 8:23.58
3. Claire Weinstein (SAND) – 8:26.06
4. Kate Hurst (TXLA) – 8:30.35
5. Michaela Mattes (Florida) – 8:34.76
6. Kayla Han (RMDA) – 8:40.39

On the final night of the 2025 Pro Swim Series, 28-year-old Katie Ledecky—widely regarded as both the greatest freestyler in history and the greatest female swimmer of all time—saved her best swim of the week for last, breaking her own 800 freestyle world record. She lowered the mark from 8:04.79, set in 2016 when she was 19, to an astonishing 8:04.12.

This is Ledecky’s 16th career individual world record, and her first since nearly seven years ago—May 16, 2018, when she set the current 1500 free standard (15:20.48) at the Pro Swim Series meet in Indianapolis.

Ledecky’s improvement came primarily from both the first and final 50s. She opened the race with a blistering 27.59 over the first lap—nearly half a second faster than her previous record swim—and by the 150 mark, she was already more than a second ahead of her old pace. Through the middle of the race, Ledecky slightly fell off her previous splits, particularly between the 200 and 400 marks, where she logged slightly slower splits. However, she began to build significant momentum again after the 500 turn, with the crowd really starting to get engaged.

Her biggest margin of improvement came over the final 50, where she blasted a 28.46—more than half a second faster than the 28.99 she recorded to close her former record.

Ledecky’s 400 splits tonight were 4:01.78 and 4:02.34, compared to her previous world record halves of 4:01.98 and 4:02.81.

Fun fact: Ledecky’s final 400 split tonight of 4:02.34 would place her as the 19th-fastest performer of all time in the individual 400 free. She ranks 3rd all-time in the event with her 3:56.46 clocking from the Rio Olympics.

Additionally, Ledecky’s first 200 (1:58.38) and last 200 (1:59.85) add up to 3:58.22, which would situate her 4th all-time in the individual 400, behind only herself, Ariarne Titmus, and Summer McIntosh. That time is nearly three seconds faster than her bronze-medal swim in the individual event at the Paris Olympics, and she’s only been faster than that time in the individual event on three occasions.

See a full splits comparison between her new and old records below.

Jillian Cox wound up 2nd in the race with an 8:23.58. It was Cox’ first 800 of the year, coming in not too far off her best of 8:19.73.

Claire Weinstein was out fast, splitting 2:01.76 on the opening 200, but just couldn’t hold that pace. she was 4:11.12 at the 400m, a virtual tie with Cox, despite being well over 2 seconds ahead of her at the 200. Weinstein finished 3rd with an 8:26.06.
