Katharine Berkoff Clocks 57.83 100 Back, Becomes Fourth-Fastest Woman Ever

2024 U.S. OLYMPIC TRIALS

In the semi-finals of the women’s 100 backstroke at the 2024 U.S. Olympic trials, Katharine Berkoff clocked a time of 57.83, becoming the fourth-fastest woman in the history of the event. She also joined Kaylee McKeown, Regan Smith, Kylie Masse, and Mollie O’Callaghan as one of the five women in history to get under the 58-second barrier in the event.

Despite posting a historic time, Berkoff didn’t even qualify for finals in first, as Regan Smith broke the 100 back American record in the next semi-final.

All-Time Top Performers, Women’s 100-meter backstroke (LCM):

  1. Kaylee McKeown, Australia — 57.33 (2023)
  2. Regan Smith, United States — 57.47 (2024)
  3. Kylie Masse, Canada — 57.70 (2021)
  4. Katharine Berkoff, United States — 57.83 (2024)
  5. Mollie O’Callaghan, Australia — 57.88 (2024)

Berkoff still remains the second-fastest American of all-time in the 100 back. She improved 0.24 seconds off her previous best time of 58.01, set at 2023 U.S. Nationals in June of last summer.

Interestingly, Berkoff’s back half from her current best and previous best are exactly the same time. However, she got faster going out.

Katharine Berkoff, 2024 U.S. Olympic trials Katharine Berkoff, 2023 U.S. Nationals
50m 28.06 28.24
100m 29.77 29.77
Total 57.83 58.01

Last year at the 2023 World Championships, Berkoff took bronze in the 100 back. Now, she’s on the verge of returning to the international stage by making her first Olympic team.

Can we all just register that Kathleen Baker, the World Record holder in this event in 2018, isn’t even one of the Top 5 performers in this event anymore?

Not only that, but after this weekend she won’t even have one of the top 40 performances all-time.

Absolutely insane

Men’s 50 breast Peaty, Qin, Shymanovich, Williamson, Martinenghi
Women’s 50 breast Meilutyte, Pilato, King, Tang, Efimova
Men’s 100 breast Peaty, Qin, Kamminga, Andrew, Martinenghi
Women’s 100 fly Walsh, Sjostrom, Huske, MacNeil, Smith & Zhang

i wonder how often it happens where the top 5 are still the current day top 5 swimmers though. Like Sun is almost certainly not a top 5 1500 free swimmer anymore, Campbell/Manuel(?) aren’t top 5 in the 100 right now, etc. I know the 100 back is like that given all 5 of the sub 58 swimmers have gone sub 58 in the past like 2 months

We can all thank a little thing called swimflation for that, and I’m all for it.

NC State backstroke is absolutely ridiculous. 4 up at Olympic Trials is something to be proud of.

At this point, you gotta give Gretchen a 52 (on a relay, maybe 51?)

Douglass a 52. Wetzel has been 52 on relay, and not sure the 4th. Simone looks to have takeout speed still, so maybe her. Maybe whoever At a low 53. Is that enough?

The Aussies are favorites but it’s winnable. Douglass can anchor a 52.00. I trust Huske can leadoff a 52 mid-high. It seems fair that on a relay start Walsh can split a 52.00. Manuel should be capable of 52 mid. Results in a 3:09 which wouldn’t have been good enough last olympics but Australia doesn’t have sub 52 McKeon anymore so should be close now. At least close enough where a subpar Aussie leg or a PB USA leg would swing it. Unlike the 4×200 where it would take an absolute miracle for the US to beat AUS.

I assume you mean 3:29 and not 3:09.

Let’s play out the numbers

Huske: 52.50
Walsh: 52.00
Manuel: 52.50
Douglass: 52.00
=3:29.00

Huske and Walsh both have doubles that session and those are significant PBs but let’s roll with it.

MOC: 52.33 (her time at trials, which she will almost certainly be significantly faster than)
Jack: 52.15 (trials time minus 0.5)
Harris: 52.02 (trials time minus 0.5)
Campbell: 52.45 (trials time minus 0.5)
=2:28.95

Even giving USA that absolute best case scenario and Australia using times much slower than their best, Australia still ekes out a win.

we actually did this at a fun relay meet in high school — used regular relay starts, but flip onto your back before you surface
