The NAB team, from Russia, touched in 3:37.97, taking a little over half-a-second off the previous record of 3:38.56 set by the United States back in 2017.
Miron Lifintsev led the team off in a massive 51.78 split to set the 2nd fastest time in history and unofficially overtake the Russian record of 51.82 set by Kliment Kolsenikov. Since the record was set leading off a mixed medley relay, the time likely won’t count towards Russia’s official National Records.
Kirill Prigoda swam the breaststroke leg in 57.56, the 14th fastest relay split in history. He also becomes the 4th fastest relay performer ever, only behind Adam Peaty, Nicolo Martinenghi, and Qin Haiyang.
They then handed the relay off to the women, who also had some of the fastest splits in the field. Daria Klepikova split 55.97 on the fly leg, only behind Zhang Yufei of China, who was one-hundredth faster at 55.96. Daria Trofimova anchored the relay in 52.66, an exact tie with the Chinese anchor Wu Qingfeng.
The only swimmer who was faster than Trofimova on the final 100 was Dutch athlete Marrit Steenbergen, who split 51.91.
It is difficult to compare this record to the previous record when looking at splits because the American’s swam a MFMF order back in 2017. The two legs that were the same were split. Lifintsev’s 51.78 was faster than the American Matt Grevers‘s 52.32, but Simone Manuel brought the American relay home in 52.17 to Trofimova’s 52.66.

The relay team was only about half-a-second of the United States World Record from Paris of 3:37.43.

bummer they’re still allowed to compete. this country should be totally banned until they can have peace especially with the swimmers from Ukraine being at the meet.
I agree, they should be “totally banned”, along with swimmers from Israel and all NATO states that armed Israel and that invaded Libya, Iraq, etc (i.e. U.S., UK, France, even Sweden, Poland and the Netherlands as they are part of NATO).
The U.S. should especially be perma-banned as it is in a state of non-stop war for almost a century now and Trump publicly ordered U.S. missile strikes on the territory of a sovereign Asian country called Iran.
Slay
We can compare the middle 200 of the Russian team vs the US world record team and see that the US split 1:54.07 (1:04.15+49.92) while Russia split 1:53.53 (57.56+55.97) or 0.54 seconds faster
I feel this “neutral” team semantics is a bit ridiculous? If the governing bodies feel so strongly about Russia’s actions in Ukraine, then the Russian athletes shouldn’t be allowed to compete at all. And I’m NOT saying they shouldn’t, but this whole “we’re going to punish you by not saying you’re from Russia” seems a bit silly in the end. Someone decided Russian swimmers could compete…. they won the race fair and square…. their names were announced…what is really accomplished by not acknowledging Russia formally? Seems like a petty slap on the hand that the Kremlin couldn’t care less about.
Sun yang should join NAB
Their women really delivered this time. Historically they’ve struggled in the mixed relays because they have two strong men and only one relatively strong woman. Klepikova and Trofimova both killed it.
NAB goes hard as a name lowkey
shouldn’t even be a thing
