Josh Liendo Clocks 43.06 100-Yard Fly, Swims #2 Time In History

2025 Men’s NCAA Swimming and Diving Championships

Florida junior Josh Liendo won his second consecutive NCAA title in the men’s 100-yard butterfly on Friday, clocking a time of 43.06. That time is a 0.01 second improvement off his best time, and it is now the second-fastest time ever in the event. The only performance faster than the Canadian’s swim is Caeleb Dressel‘s NCAA record time of 42.80.

In the same race, Arizona State sophomore Ilya Kharun clocked a best time of 43.49 to finish second and rank as the fourth-fastest performer of all-time, while Georgia redshirt senior Luca Urlando improved upon his best time to finish third and rank fifth in history.

All-Time Top Performers, Men’s 100-Yard Butterfly:

1. Caeleb Dressel, Florida — 42.80 (2018)
2. Josh Liendo, Florida — 43.06 (2025)
3. Youssef Ramadan, Virginia Tech — 43.15 (2023)
4. Ilya Kharun, Arizona State — 43.43 (2025)
5. Luca Urlando, Georgia — 43.49 (2025)

Although Liendo still has yet to catch Dressel’s record, he has now been faster than Dressel’s second-fastest performance time of 43.58 on six different instances. Liendo has now been 43.06, 43.07, 43.23, 43.30, 43.40 and 43.49 all on separate occasions, holding five of the seven fastest performances of all-time in the 100 fly.

There’s still a gap between Liendo and Dressel on both halves of their respective personal bests, as Dressel is 0.14 seconds faster than Liendo on his front half and 0.12 seconds faster on his back half.

Split Comparison:

Liendo will still have one more season to take down Dressel’s record in the 100 fly. But for now, at the 2025 NCAA Championships, he has the 100 free left to race, where he is the two-time defending champion and top seed. Earlier this meet, he finished second in the 50 free (18.23).
