Cameron McEvoy broke the men's 50-metre freestyle world record on Friday, clocking 20.88 seconds at the China Swimming Open in Shenzhen.
TLDR
Cameron McEvoy broke the men's 50m freestyle world record on Friday, clocking 20.88 seconds at the China Swimming Open in Shenzhen. The 31-year-old Australian beat César Cielo's 17-year-old mark set during the supersuit era. McEvoy trains just 2km per week in the pool, relying on strength training instead of traditional high-volume swim workouts.
KEY TAKEAWAYS
The 31-year-old Australian shaved 0.03 seconds off César Cielo's mark of 20.91 seconds, a record the Brazilian set on July 30, 2009. McEvoy's previous personal best was 21.06 seconds.
"I knew I had a chance to do a PB. My old PB was 21.06, so maybe 20.99?" McEvoy told reporters poolside. "But doing 20.88 is unreal. It's crazy."
McEvoy is the reigning Olympic champion from Paris 2024 and won the 50-metre freestyle world title in 2025. He becomes the first Australian to hold this record since Eamon Sullivan set three world records in the event in 2008.
The supersuit factor
Cielo's 2009 record arrived during what swimming calls the supersuit era. Polyurethane bodysuits from Arena and Jaked trapped air and reduced drag. Swimmers broke 67 world records that year alone.
FINA banned the suits effective January 1, 2010. Many records from 2009 stood for more than 15 years because subsequent swimmers raced in standard textile suits.
McEvoy wore a textile suit on Friday.
Cielo responded on social media within hours.
Congrats, Cam. Lightning fast swim! Incredible! I saw a phrase a while ago that perfectly captures what you've been doing. You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete. Congratulations!

Two kilometres a week
McEvoy did build a new model. He scrapped the training methods used by sprint swimmers for decades.
The old approach: roughly 30 kilometres of swimming per week, with gym sessions squeezed around pool work.
McEvoy's approach since 2023: two kilometres of swimming per week maximum. Heavy gym work. Strength training drawn from sprint cycling, athletics and other speed sports.
He works with coach Tim Lane in Brisbane.
"The 50 metres, I look at it as a strength-based skill," McEvoy said in an interview before Friday's race. "It's different to the other events in swimming. A lot more strength and power is involved, and men peak in strength into their 30s. Well into their 30s."
McEvoy holds a physics and mathematics degree from Griffith University. Teammates call him "The Professor." He applied the same analytical thinking to his own training that he once applied to problem sets.
A 50-metre freestyle race lasts roughly 21 seconds. Why train like a distance swimmer?
Burnout and rock walls
McEvoy burnt out after the Tokyo 2020 Olympics, delayed to 2021 by the pandemic. He took three months off. Completely off.
During that break, he started rock climbing. He realised he had never done proper strength training. Swimming had always prioritised pool volume over gym power.
He returned to the pool with a different philosophy.
"It's significantly extended the longevity of my career," McEvoy said. "I'll be 38 in Brisbane 2032, so I'm thinking I could be halfway through my career right now."
McEvoy turned 31 last year. If his projection holds, he plans to compete at the Brisbane Olympics at 38.
What the record means
McEvoy's swim on Friday matters beyond Australian swimming history. It offers evidence that sprint training methodology, not equipment or youth, produces world-record times.
Cielo needed a polyurethane suit. McEvoy needed a weight room.
The record may force coaches worldwide to reconsider how they train sprint swimmers. For decades, high-volume pool work defined the sport. McEvoy demonstrated that approach might be wrong, at least for events lasting under 25 seconds.
Australian swimming continues a dominant run. The nation topped the medal table at Paris 2024 and has produced world champions across multiple stroke disciplines. McEvoy's record adds to that tally.
The next test: the World Aquatics Championships in July. McEvoy will defend his 50-metre freestyle title in Singapore.
