SPORTS & SWIMMING — Australia completed a dominant sweep of the men's and women's 400-metre freestyle events at the 2026 Pan Pacific Championships, with Sam Short breaking a championship record that had belonged to Australian swimming legend Ian Thorpe since 1999.
Short won the men's final in 3:40.52 at the William Woollett Jr Aquatics Center in California, finishing well ahead of China's Zhang Zhanshuo, who took silver in 3:42.42, and American Aaron Shackell, who finished third in 3:43.44.
His performance erased Thorpe's 400m freestyle championship record of 3:41.83, set in Sydney more than two decades ago. Short also surpassed the previous U.S. Open record of 3:43.33.
Short Finally Breaks Thorpe's Mark
Thorpe's record had survived since 1999, making it one of the longest-standing marks at the Pan Pacific Championships.
Short attacked the race from the beginning and maintained control throughout the final.
The 22-year-old Australian eventually touched the wall in 3:40.52, producing both a personal best and a new championship record.
For Short, breaking Thorpe's mark carried particular significance because Thorpe was one of the swimmers he admired while growing up.
A Record That Had Been Waiting for 27 Years
Thorpe established the previous championship record in Sydney in 1999.
Short's swim therefore ended a remarkable 27-year wait for a new Pan Pacific record in the event.
It also added another chapter to Australia's long history in the 400m freestyle.
Short said he believed he could have gone even faster, suggesting that the record-breaking performance may not represent his full potential.
Short Is Building Serious Momentum
The victory was not an isolated result.
Short had already won the men's 800m freestyle earlier in the Pan Pacific Championships.
He also entered the competition after winning the 400m freestyle at the Commonwealth Games in Glasgow.
His recent performances suggest that the Australian is developing into one of the leading distance freestyle swimmers of his generation.
Pallister Completes Australia's Sweep
Australia's success continued in the women's 400m freestyle.
Lani Pallister won the event in 3:58.42, recording a personal best and holding off American swimming great Katie Ledecky.
Ledecky finished second in 4:00.15, while New Zealand's Erika Fairweather took bronze in 4:02.35.
Pallister established a substantial advantage early and managed to withstand Ledecky's late challenge.
Ledecky Could Not Catch Pallister
Ledecky, one of the most decorated swimmers in Olympic history, attempted to close the gap during the final stages of the race.
But Pallister had created enough separation earlier in the race to protect her lead.
The Australian's final time of 3:58.42 marked another important step in her development at the international level.
Pallister Arrived in Strong Form
Pallister entered the Pan Pacific Championships after an impressive Commonwealth Games campaign in which she won four gold medals and one silver.
She had also produced strong performances earlier in the Pan Pacific meet, including a victory over Canadian star Summer McIntosh in the 200m freestyle.
Her 400m victory over Ledecky added another major result to an already successful season.
McIntosh Misses the Final
Canadian world-record holder Summer McIntosh was unable to reach the women's 400m freestyle final.
She recorded the ninth-fastest time in the heats and instead competed in the consolation final, where she finished in 4:00.58.
McIntosh later described the experience as a lesson and said she would make sure the mistake did not happen again.
The result was particularly unusual for a swimmer who has established herself as one of the world's strongest all-around competitors.
Australia Added More Gold
The 400m freestyle sweep was not Australia's only success in the session.
Australian Matthew Temple won the men's 100m butterfly in a championship-record 50.39 seconds.
Australia's Alex Perkins also earned bronze in the women's 100m butterfly, finishing behind American winner Gretchen Walsh and Canada's Taylor Ruck.
Walsh won the women's event in a championship-record 55.15 seconds.
A New Generation Is Emerging
Short and Pallister's performances highlight the depth of Australia's current swimming programme.
Australia has historically produced some of the world's greatest swimmers, including Thorpe, but the country's current generation is beginning to create its own records and rivalries.
Short's decision to chase Thorpe's mark rather than simply protect the lead showed the confidence of a swimmer who believes he can compete at the highest level.
Breaking Thorpe's Record Means More Than One Race
Records in swimming are often temporary.
What makes Short's achievement significant is the identity of the swimmer whose mark he replaced and the length of time the record survived.
Thorpe remains one of Australia's most influential swimmers, and his 400m freestyle performances helped define an era of Australian dominance.
Short has now put his name alongside that history.
The Next Challenge Is Consistency
One exceptional swim can announce a swimmer to the world.
Repeated performances at the highest level are what establish a career.
Short will now face the challenge of maintaining this form against the world's strongest distance swimmers.
Breaking a record is difficult. Staying at record-breaking level is even harder.
Australia's Freestyle Depth Is Becoming a Major Advantage
The simultaneous victories of Short and Pallister demonstrate Australia's strength in the freestyle events.
Both swimmers were able to produce major performances against strong international fields.
That depth gives Australia more options for individual events and relay teams as the international swimming calendar moves toward its next major championships.
Our Perspective
Sam Short's victory is significant not simply because he won another gold medal.
He removed a record that had survived since the era of Ian Thorpe and did so while producing a personal best.
But the bigger story may be what comes next.
Breaking a legend's record gives Short recognition. Repeatedly defeating the world's best will determine whether he becomes a legend of his own.
Conclusion
Sam Short has broken Ian Thorpe's long-standing Pan Pacific Championships record in the men's 400m freestyle, winning gold in 3:40.52 at the 2026 championships in California.
Lani Pallister completed Australia's sweep by winning the women's 400m freestyle in 3:58.42 ahead of Katie Ledecky and Erika Fairweather.
Short's record-breaking swim adds another major achievement to a season that already includes Commonwealth Games and Pan Pacific titles.
Australia's latest generation has made its presence clear, and Short's destruction of a 27-year-old Thorpe record could mark the beginning of a new chapter in Australian freestyle swimming.
