Japanese star Daiya Seto has been swimming like a man on a mission for the past week or so, putting up three lifetime bests, and rewriting all-time top performances lists, in the 200 fly, 200 IM, and now the 400 IM. Here’s race video from Seto’s 400 IM, a 4:06.09 effort that makes him the 5th-fastest performer in history.

Seto actually was about seven-tenths of a second under world record pace after the fly leg, but fell behind on the backstroke leg. Here’s a quick comparison of Seto’s split to Phelps’ world record splits.

  • Phelps 2008: 54.92/ 1:01.57 / 1:10.56 / 56.79 = 4:03.84
  • Seto 2020: 54.22 / 1:03.46 / 1:09.83 / 58.58 = 4:06.09

Even if the world record proves to be out of reach this summer, Seto would not need to shave much time off his swim to quickly jump up to #3 all-time, as he’s less than two-tenths of a second behind Kosuke Hagino and Chase Kalisz on the all-time list.

His turnover is pretty incredible for a 400 LCM IM, roughly the same as the guys in the finals of the 200 yard IM at NCAAs, maybe even faster.

He starts the 400IM as if it was a 50 fly.
