Men’s 400 IM

  2. Duncan Scott – LON – 3:59.81
  3. Max Litchfield – ENS – 4:01.31
  4. Andrew Seliskar – LAC – 4:06.01
  5. Chase Kalisz – LAC – 4:06.27
  6. Anton Ipsen – CAC – 4:09.09
  7. Mark Szarnek – CAC – 4:10.52
  8. Finlay Knox – LON – 4:13.23

In the same race at the International Swimming League Finale in which Daiya Seto took down the World Record, Duncan Scott became the first British swimmer in history to break the 4-minute barrier in the 400 SCM IM. The previous mark of 4:00.18 was set by Max Litchfield in December 2018 at Sheffield.

Swimming for London Roar in the ISL finale, Scott finished in second place behind Seto, 1.5 seconds ahead of third-place Litchfield. Scott beat his own Scottish National Record of 4:01.20, which he established at European Short Course Championships. In just over a month, he has gone from a PB of 4.06.00 at BUCS to 4.04.55 at the ISL European Derby in London, to 4:01.20 at Euros, to 3:59.81 in Las Vegas.

The 400 IM record marks the third British and Scottish SCM marks for Scott in the last two weeks. He also broke the 200 SCM freestyle British and Scottish Records and the 200 SCM IM British and Scottish Records at European Short Course Championships in December. Earlier this year he broke the LCM British Records in the 100 free (47.87) and 200 free (1:44.91).

2019 has been a busy year for the Scottish record books. In SCM, Scott has lowered the 50 free record twice; it now stands at 21.25. He broke his own 100 free (46.58), 200 free (1:40.92), 200 fly (1:54.43), and 100 IM (52.15) records. And he registered new national marks in the 200 IM (1:52.33), and now the 400 IM (3:59.81). In LCM he owns the 100/200 free records, as well as the 100 fly (52.25).

Scott split his record-breaking 400 SCM IM as follows:

  • Fly – 25.52 / 29.15 = 54.67
  • Back – 30.43 / 30.42 = 1:00.85
  • Breast – 34.13 / 34.85 = 1:09.00
  • Free – 27.83 / 27.48 = 55.31

ISL London, straight to Euros, straight to Scottish Nationals, all with packed schedules, still shows up to ISL finals flying. He’s certainly putting in the hard yards to be in top form in Tokyo.

Looking good for Tokyo. Hopefully, he doesn’t overdo his schedule like he did at Euros so he can get multiple medals.

I would guess the Europeans were a training event. Shame we did not see the 200Freestyle from him in Las Vegas

All of these meets are just training for him – stacking them on top on each other, lots of races with short breaks, no shave or taper…..looking great for 2020…..wait till he’s rested! 👍

The British Phelps, 3.59 in the 400 IM and 20.5 relay start a couple of weeks ago. Versatile 100% and also a machine competing.

I just crapped myself thinking Phelps came out of retirement and did those times in some time trial.

British Dresselis definitely more appropriate. We can start comparing him to Phelps after he gets a few handfuls of Olympic gold medals.

i think he meant more the phelps-like versatility. phelps really is the only other person who had an insane 100 free time and an insane 400 IM time that i can think of simultaneously. Scott’s 46.1 lcm relays split is indeed insane, and phelps 47.5 lead off, at the time, was pretty darn insane (0.01 off, before australia’s sullivan’s leg, the world record)…and of course phelps’ 4:03 is insane; and i think scott’s 3:59 is pretty darn amazing considering seto and lochte both go 3:54….i also think Scott has a seriously good chance at winning the Olympic Gold in both the 200 IM and 200 free

The one commonality is that they are brutal racers who can just get up and race with little rest and handle incredible schedules. Would love to have seen Scott in NCAAs with 17 races in a 3 days. He would’ve been an animal like Dressel was.

Also, both absolute money on relays. Always deliver.

It’s actually quite disappointing that London roar ended up losing points because their second swimmer didn’t swim within a specific time .. so all of Duncan Scott’s hardwork gets undone

46.16 100 free split and a 3:59 scm 4IM? Absolutely insane
