Three additional athletes have qualified for the 2025 World Aquatics Championships on night four of the Toyota National Championships. The meet will select rosters for three upcoming international meets: the World Aquatics Championships, the World University Games, and the World Aquatics Junior Swimming Championships.

See below for the qualifications for the 2025 World Aquatics Championships.

 Women’s 400m Freestyle – FINAL

1 – Katie Ledecky (Bethesda, Md./Gator Swim Club), 3:58.56

2 – Claire Weinstein (White Plains, N.Y./Sandpipers of Nevada), 4:00.05

3 – Bella Sims (Henderson, Nev./Sandpipers of Nevada), 4:07.11

Ledecky on her meet thus far: “It’s been good. A lot of fun and feeling good about my races, so I can’t complain.”

Ledecky on her 400 freestyle: “I felt really good in warmup so I just wanted to go for it, swim it as similarly as I could to Fort Lauderdale. I was out a little fast tonight, and definitely paid the price in the last 100, but still pretty happy. I was able to hold it together even through the pain.”

Ledecky on Lilly King’s last domestic meet: “Lilly is awesome. It just means so much to the team and so many swimmers on the pool deck. You know, the ones that have been around a while and some of the up-and-coming swimmers, she’s always someone who is going to cheer you on and make you feel welcome on Team USA. All of those things. I’m really excited to get one last World Championships with her and be by her side for some of her last races. It’s just so great to see her having so much fun with this and she just seems so at peace with the end of her career, and that’s what you want to see in a pro and your friends.”

Sims on her meet: “Honestly, I’m actually really proud of myself. I didn’t want to go in it with any expectations, and Ron (Aikins) was very vocal about going out there. I’m just trying to go out there and have fun with everything that I’m doing, and I think I’m doing pretty good at that.”

Men’s 400m Freestyle– FINAL

1 – Rex Maurer (Pasadena, Calif./Longhorn Aquatics), 3:43.33*

2 – Luka Mijatovic (Pleasanton, Calif./Pleasanton Seahawks),3:45.71

 3 – Ryan Erisman (Windermere, Fla./Laker Swim), 3:46.01

* U.S. Open record

Maurer on his meet: “Yeah, it’s been a super fun meet so far. Obviously, making the team on the first day was a big monkey off the back and I think it kind of let me get the relief off and focus in on my next few events with a little less pressure.”

Maurer on his race: “I was due for a big drop in the long course pool, and I am glad I was able to put it together. I was definitely expecting something around there. This season, I’ve been really focusing on jumping on it a little earlier. Earlier in my career, I kind of liked (to pick up speed) with about the 125 left, and now I’m really trying to push around the 200 (meter mark). I really tried to put my legs into it more. So, with those two combined, it catapulted me to the new times.”

Women’s 100m Breaststroke – FINAL

1 – Kate Douglass (Pelham, N.Y./New York Athletic Club), 1:05.79

2 – Lilly King (Evansville, Ind./Indiana Swim Club), 1:06.02

3 – Alex Walsh (Nashville, Tenn./New York Athletic Club), 1:06.50

King on her last race in the United States: “It was good…I was hoping tonight would be a little special, and it was an awesome crowd. It was fun to say goodbye. This isn’t my last meet, we still have Worlds in seven weeks, so there is still time to get back to work. It was just my last meet here.”

King on her longevity: “I’m really fortunate I’ve hardly ever had an injury, but I think a lot of that credit goes to taking care of myself. I take really good care of my body. I take pride in taking care of my body. I try to teach all of the younger athletes on the team to make sure you are stretching, make sure you are foam rolling. If you can get body work done during the week, do that. Make sure you are Normateching. I think that’s been a big thing I’ve credited it to, and I think I also just got lucky…and I like to race. Racing is always good.”

Men’s 100m Breaststroke – FINAL

1 – Campbell McKean (Bend, Ore./Bend Swim Club), 58.96

2 – Josh Matheny (Pittsburgh, Pa./Indiana Swim Club), 59.18

3 – Nate Germonprez (Austin, Texas/Longhorn Aquatics), 59.89

McKean on his race: “Based off this morning, my first 50 tempo was a little bit slower than what I wanted. Tonight, I just wanted to stay lighter and push that tempo and be able to come back faster than I did this morning.”

McKean on going 58: “Honestly, the goal tonight, I had my eyes set on Michael (Phelp’s National Age Group record), but my coach and I have been talking, and if I do what I do in practice, I can probably go 59 low. Being able to go 58 was very shocking to me.”

McKean on his week: “Super grateful for this week. Super fun. I missed graduation for this, so I’m very glad I missed it. I think it’s a great opportunity to see what I can do with my career.”

Women’s 100m Backstroke – FINAL

1 – Regan Smith (Lakeville, Minn./Longhorn Aquatics), 57.69

2 – Katharine Berkoff (Missoula, Mont./Wolfpack Elite), 58.13

3 – Claire Curzan (Cary, N.C./Tac Titans), 58.60

Smith on her qualifying events: “Overall, I’ve never qualified for four individual events at Worlds before, so I’m psyched. I would say that’s positive, so I’m just going to choose to focus on the positives. Especially because it’s 2025, it’s not 2028.”

Smith on the depth of USA Swimming: “USA Swimming has so much talent, and if there’s one thing I’ve learned from this meet it’s that you can’t even really breath for a second because there are always going to be people who are so hungry, so talented, and so motivated. If you slack off for even a second, someone is going to grab your spot. It’s something to be cognizant of in the future, and I definitely got a taste of it this week, so it’s great. It’s motivating and it definitely lights a fire under me.”

Smith on her meet: “This whole year has been about a big fat mental break, and physical break…In this nine-month season, I think I’ve honestly spent a combined six weeks of really intense or aerobic training. I was prepared for the meet to go something like this. At the end of the day, I’m a really competitive person, and it’s one thing to try and prepare yourself for a meet like this, but it’s another thing to live it. It’s definitely humbling, and I think it lights a little bit of a fire under me, but again I do think it’s great practice to recognize it’s okay if this happened because I spent this year doing what I did. I also think it’s good practice to not be super hard on myself when things don’t go the way I want them to, even if I spent all year preparing for something like this to happen.”

Men’s 100m Backstroke – FINAL

1 – Tommy Janton (Kennett Square, Pa./University of Notre Dame), 53.00

2 – Jack Aikins (Atlanta, Ga./SwimAtlanta), 53.19

3 – Daniel Diehl (Cumberland, Md./Wolfpack Elite), 53.35
