Sam Short Unloads 3:40.67 400 Free Personal Best For #1 In World Rankings

2026 AUSTRALIAN SWIMMING TRIALS

Leave it to Sam Short to give Aussie trials a dynamite start. In the meet’s first event, the men’s 400 freestyle, he gave the World and national records a proper scare with a 3:40.67, marked by an aggressive front half. 

Though he missed the aforementioned records, it still marked one of the best swims of the 22-year-old’s career and one of the strongest performances in any event anywhere in the world this year. The time checks in as Short’s lifetime best — .01 under the 3:40.68 he delivered to take the 2023 World Title. It also keeps him as the #5 all-time performer.

All-Time Performers, Men’s LCM 400 free:

  1. Lukas Märtens (GER) — 3:39.96, 2025
  2. Paul Biedermann (GER) — 3:40.07, 2009
  3. Ian Thorpe (AUS) — 3:40.08, 2002
  4. Sun Yang (CHN) — 3:40.14, 2012
  5. Sam Short (AUS) — 3:40.67, 2026

Domestically, Short maintains his place as the second-fastest performer ever, trailing Ian Thorpe, and it marks the fifth-fastest performance ever from an Australian, with Thorpe having clocked 3:40.08, 3:40.14, 3:40.54 and 3:40.59 during his legendary career.

With Commonwealth Games and Pan Pacs privileges secured, Short takes the pole position in the season’s world rankings. He leapfrogs over previous #2 Märtens (3:41.76) and former #1 Zhang Zhanshuo of China (3:41.55) to lead the globe by nearly a second. Short previously had the #3 spot at 3:42.53 from the Australian Open.

To bring home just how aggressive Short went on his first half today, compare his splits this evening to his previous pb as well as Märtens’. It was under Märtens’ world record pace from the 150 to the 350. That swim in its own right was already known for an aggressive first 200.

I never tire of saying this: Thorpe pulled the brakes at the finish of that 2002 swim, or he would have been 3:39

Yep. Would have been one of the longest surviving WRs

The longest lasting one for sure. Would have lasted at least 22 years and 9 months, potentially even longer.

He said it himself, had he known he’d be breaking WR, he wouldn’t have slowed down at 5m from the finish. He had many events at 2002 commonwealth games which included 100 back.

What are the odds he break’s Thorpe’s Australian record and challenges the WR this year?

I can’t see anyone going a 3:38 now. 3:39 sure, not 3.38

3:40 a quarter century ago. The event stalled, and is due for a big breakthrough.

3:38 this year!!

I think there are 3 great mysteries:

1. The Big Bang.
2. Melania.
3. 6-7.

Nobody is ever going to properly explain these.

This statement Domestically, it stands as the #2 Australian performance all-time, trailing only Ian Thorpe’s legendary 3:40.08 from nearly a quarter-century ago.

Is mistaken. He is the #2 australian performer. But Thorpe swam under that time 3 times, so its not the #2 Australian Performance.

Short breaks this WR at Comm Games, then Maertens breaks it at Europeans, and then Zhang Zhanshuo breaks it at Asian Games

Maybe it’s that his front speed is there now but he might break his 800 free Australian record this week. Hacketts 1500 record should be safe for now.

I don’t want to give absolutes but I think that going out in 1:47.3 in the 200
could maybe make him hurt the reason of this week.
