Kate Douglass Breaks Cate Campbell’s World Record With 50.19 100 Freestyle

Top 8 Finishers:

  1. Kate Douglass (USA) – 50.19
  2. Mollie O’Callaghan (AUS) – 51.44

Kate Douglass added another World Record to her resume on Sunday night, winning the 100 freestyle in a 50.19 while in Westmont. That broke the previous World Record of a 50.25 set by Australia’s Cate Campbell back in 2017.

In addition to a World Record, Douglass broke Gretchen Walsh‘s American Record of a 50.31 set last December at the 2024 SCM World Championships.

Split Comparison

Douglass Campbell G. Walsh
50 23.88 24.21 23.9
100 26.31 26.04 26.41
Final 50.19 50.25 50.31

Douglass was under World Record pace at the 50 mark and held on to out touch the previous line by 0.06 seconds. Coming into tonight, Douglass had a lifetime best of a 50.76 from last December’s World Championships.

With her World Record here in the 100 free, Douglass now holds the SCM World Records in the 100 free, 200 breast, and 200 IM. She also is a member of the US women’s 4×100 free, women’s 4×100 medley, and mixed 4×50 medley relays that hold the SCM World Records.

Gretchen Walsh (50 free, 50/100 fly, 100 IM) and Summer McIntosh (400 free, 200 fly, 200 IM) are the only other swimmers to have SCM in three different strokes.

Further proof that Kate and the 200 IM are ‘never, never, never….getting baaaack together’

If true, it is more so due to the 100 BR than 100 FR.

The heats/semis of the W 200 IM are scheduled on the same day (Day 1) as the heats/final of the W 4 x 100 FR-R at the World Aquatics Championships. Meanwhile, the heats/semis of the W 100 BR are scheduled the next day (Day 2).

I wish we could see a short course 50 from her this year. That’s where the world cup only being 3 stops hurts a bit more. The old cluster format might have allowed her to mix it up eventually.

Would love for them to go back to it with 3
or 4 clusters of 3 meets. They could do an americas cluster (north or south), Europe, Asia (central or eastern) every year and rotate sites. Maybe do an Oceania cluster every few years !

Then you could do crowns for each “cluster” and encourage some event variety as well

That is the most tenacious short course race from Douglass since she defeated Maggie for the NCAA championship as a senior.

I don’t count breaststroke as tenacious, especially the way Douglass swims it.

She always seems to defer a bit to Gretchen when they are in the same race. That’s what I’m getting at. Kate can’t rally past Gretchen. Her only chance is gamble with the lead. It never happens. Finally the fear and pride factor against an Australian allowed Kate to push the early boundaries, and be rewarded for it.

She raced and beat Gretchen many times back in college. In fact I don’t think Gretchen ever beat her head-to-head at ACCs or NCAAs:
50 free: 2022 ACCs & NCAAs
100 free: 2022 & 2023 ACCs
100 fly: 2023 ACCs

Killing me that we’re all going to have to wait about two and a half years to know what events Kate is going to do in LA. I’m not ruling out the pole vault.

Decathlon?

Hammer throw, some boxing. Maybe some equestrian events.

I know she is going to have an incredibly busy line-up, but could we please see her swim a leg on the 4×200 free relay? She has to be good for a 1:54-low with a relay start, and the U.S. needs four women who can swim a sub-1:55 in order to beat the Aussies.

I know what event is my most anticipated:

women’s 400 meter track where I hope Sydney McLaughlin-Levrone will finally break the long overdue tainted Marita Koch’s WR (if she hasn’t broken it beforehand)

I can imagine the roar erupted in the stadium.

Sydney better try to get that record before Los Angeles. She’ll be 28. Very few sprint records are broken at that age or beyond. It’s the same reason I knew Shericka Jackson wouldn’t get rid of Florence Griffith-Joyner’s 200 record once she failed at Eugene 2022.

plus meets like the Diamond League avoid the exhausting 3 day prelims, semis, finals ordeal like the Olympics and World Champs
(and yes it would be great to see flo-jos records gone too)

I think sometimes it gets overshadowed by the last 18 months that GW has had, but Kate’s last 18 months have been extraordinary as well with individual world, short course and olympic titles + numerous ARs & WRs. The only thing she is “missing” now is an individual LCM world record, and it seems like she may be roaring towards that in breaststroke
(I dont think she has a good shot elsewhere but never say never i suppose, I didn’t have her breaking this before walsh)

Kate Douglas is crazy good at 50 & 100 free, probably even 200 free, 100 & 200 breast & 200IM.
Walsh is crazily good at 100 fly.

I would add Walsh is also crazy good in 50 fly and quite good in 50 and 100 free.

I still think Kate has Walsh pretty well covered. Not much a fan of 50s outside of freestyle.

I think peak Emma at her Tokyo Olympics form could have gone 49 something. Maybe 49.5 – 49.8.

Great swim from Kate. Unexpected as well.
