Yu Zidi, 13, storms to Asian Games butterfly gold in record time

China's Yu Zidi, aged 13, won gold in the women's 200m butterfly at the Asian Games on Sunday, 20 September 2026.

She touched in 2:05.08 at the Olympic pool in Tokyo. That time set a new Asian Games record in the event, according to BBC.

The margin was huge. Yu finished 3.36 seconds ahead of teammate Chang Mohan, who took silver, AFP reported. In a 200m race, swum over four lengths of a 50-metre pool, that is several body lengths. It is the kind of gap you rarely see in a major butterfly final.

Her record also rewrote the recent history of the event. Yu beat the previous Asian Games mark held by compatriot Zhang Yufei from three years ago by almost half a second.

She was not impressed. Yu described the swim as "only so-so" after the race. It was still her first major gold medal.

The result continues a rapid rise. Last year, aged 12, Yu became the youngest swimmer ever to win a World Championships medal when she took bronze with China's 4x200m freestyle relay team.

That relay medal came from heats and finals combined, the usual way relay medals are awarded in swimming. She has since added senior domestic titles and records. Less than a month after her 13th birthday she claimed her first Asian record at China's National Games, and in March she swam 2:05.90 for 200m butterfly at the China Open in Shenzhen.

Yu turns 14 next month. She will race two more individual events at these Asian Games.

What makes this stand out is the stroke as much as the age. The 200m butterfly is often seen as the toughest race in the pool. It demands rhythm and strength across all four lengths, with no chance to hide tired arms. To lead from early and still finish more than three seconds clear suggests control, not just speed.

For fans, this means watch the clock as well as the medals. A junior record is a promise, not a career. But 2:05.08 at 13, in a championship final, is a serious time at any age.
