Cameron McEvoy Breaks a 50m Freestyle Record From the Super-Suit Era

20.88 seconds: the first time anyone has beaten Cesar Cielo's 2009 mark, set in a now-banned polyurethane suit that made that generation of records notoriously hard to touch.

Australia's Cameron McEvoy swam 20.88 seconds in the men's 50m freestyle final at the China Swimming Open in Shenzhen in March, breaking a world record that had stood since December 2009. The mark he took down was Brazilian Cesar Cielo's 20.91, and he took three hundredths off it.

The margin of victory was just as striking. For a one-length race it was enormous. The USA's Jack Alexy was second in 21.57, and McEvoy's fellow Australian Kyle Chalmers third in 22.01. McEvoy was more than half a second clear of the next man in a race that usually comes down to hundredths.

He had not expected it either. "I knew I had a chance to do a PB. My old PB was 21.06, so maybe 20.99, but doing 20.88 is unreal. It's crazy."

The record from the super-suit era

The record's age is the real story. Cielo swam 20.91 at the Brazilian championships in São Paulo in December 2009, at the very end of swimming's super-suit era. For about two years, high-tech full-body suits, the most extreme made of polyurethane, had given swimmers extra buoyancy and reduced drag, and world records fell at a rate the sport had never seen. The governing body banned them from the start of 2010, about two weeks after Cielo's swim.

Most of the records from that period eventually fell as training, technique and textile suits caught up. Cielo's other world record, 46.91 in the 100m freestyle, was broken by China's Pan Zhanle in 2024. But the 50m free held on. For more than 16 years, through the whole textile era, nobody had swum faster than a man in a suit that is no longer legal. McEvoy did it in the suit everyone races in today.

Who Cameron McEvoy is

McEvoy is 31 and from the Gold Coast in Queensland. For much of his career he was best known as a 100m and 200m freestyler. He later turned his focus to the 50m, and it paid off. He won the world 50m title in Fukuoka in 2023 in 21.06, the Olympic title in Paris in 2024 in 21.25, and the world title again in 2025.

That run of titles meant the record was not a surprise from nowhere. But even for the best 50m freestyler of his era, getting under 20.91 had looked out of reach. His best before Shenzhen was the 21.06 from Fukuoka.

Why it came at 31

McEvoy has a clear view of why he is getting faster at an age when many swimmers have retired. "The 50m, I look at it as a strength-based skill," he said. "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."

It is a useful way to understand the event. The 50m freestyle is swimming's purest sprint: one length, no turn and no tactics beyond raw speed off the blocks and through the water. Endurance barely matters. Power does, and power, as McEvoy says, keeps developing long after the age when distance swimmers are at their peak.

What it means

A record from 2009 finally falling in 2026 says as much about how unusual Cielo's original swim was as it does about McEvoy. But the size of the margin in Shenzhen suggests the sprinter who finally got past it may not be finished. He broke the record at a spring meet, not a championship, and there was a whole summer of racing still to come.
