SUN Yang (CHN), 3:41.38, after became world champion of 400m freestyle:
Is it the first of four potential golds?
"It is too early to say so. I trained a lot and I must admit I am getting older, and suffer some injuries. We will see during the week how it works and I will concentrate on one race after the other"
HORTON Mack (AUS), 3:43.85, finished 2nd place:
"The biggest disappointment was the time. I wasn't as fast as I can. I need to improve for the next couple of events towards Tokyo. I tried to be stronger in the front end, but I was just too soft, I think. I need to be harder to myself. I need to recover fast to prepare for 200m for tomorrow."
DETTI Gabriele (ITA), 3:43.93, won the bronze medal:
"It is my first medal at the World Championships and it makes me happy as I missed the championships 2 years ago, due to injury. Today I tried to catch Nick Horton on the last 50 metres, but it did not work. In the end, it does not matter, which colour the medal has!"
SZILÁGYI Liliána (HUN), 57.75, finished 9th place in women's 100m butterfly:
"It is amazing to compete in front of the Hungarian audience. There is a lot of support from the fans, which is very gratifying. I had a very good time, I could even improve the time I swam in the morning, so I can't say I'm disappointed."
CSEH László (HUN), 23.51, finished 11th place in men's 50m butterfly:
"I should have swum a better time as I did in the morning. This afternoon wasn't that great. In terms of pace, I'm fast. I have to be good at 100 and 200 metres. This was good for warming up."
SMITH Leah (USA), 4:01.54, won the silver medal:
"It was a really exciting event, especially the start with the marching in! The Hungarian crowd was cheering for the home competitors, which was awesome! For me, the 400m freestyle is my favourite event, and I am satisfied with the second place as I had not ever swum together with Katie Ledecky in an individual event at the world championships! It was a new experience.”
LI Bingjie (CHN), 4:03.25, won the bronze medal:
„It is very nice to win a medal in my very first World Championships! I am not 100% happy because I did not swim my personal best"
KAPÁS Boglárka (HUN), 4:04.77, finished 5th place in women's 400m freestyle:
"I'm neither happy about the place nor about the time, but I'm glad it's over. It might sound strange, but I needed to experience what it is like to swim in front of the Hungarian audience, and it's better here than on 400 metres, which is not my event. It's very difficult to concentrate and not to lose my attention when the audience is cheering. I would love to just enjoy it and wave back at the people all day long. I did my best and tried to focus only on swimming, it was enough for this. I'm very much looking forward to the 1500 metres."
KÉSELY Ajna (HUN), 4:05.75, finished 6th place in women's 400m freestyle:
"I feel wonderful. Duna Arena has become my favourite swimming pool. This swimming didn't go so well, even though for me the mornings are usually tougher. It doesn't matter, I'm glad. I'm very thankful for all of those who help me and support me, especially for my family and my coach."
PEATY Adam (GBR), 57.75, got in the final in men's 100m breaststroke with a new championships record:
"It was a pretty good semi-final and a really good start, and hopefully tomorrow I can get a little bit faster. I didn't really see that I did a championship record, I just wanted to enjoy the crowd, and do my best."
ADRIAN Nathan (USA), 3:10.06, after team USA won the men's 4x100 freestyle relay:
"The French are not here, as a long term opponent of us, but we have the Brazilians, as a new one! I like their relay and it does not matter how long is the distance to the next one. The main thing is to win and it does not matter if it happens with one hundred or a second!"
HOSSZÚ Katinka (HUN), 2:07.14, got in the final with the best time in women's 200m IM:
Everything went well so far, I could focus on swimming better in the afternoon. In the morning, it was strange to swim in front of so many Hungarian spectators and fans. This one was a much better-concentrated competition. And the crowd definitely boosts my performance a lot!
JAKABOS Zsuzsanna (HUN), finished at 12th place in women's 200m IM:
"With this 12th place, I managed to improve my position as in the preliminaries I was the 15th. It is not a secret that I wanted to swim better and get into the finals. The preparation went well and we calculated on it. However, this is a fantastic experience that I could swim in front of so many people and now this is why I am still smiling as I think I put all my strength in it and it was amazing. There will be some relay events and the 400 metres relay on the last day, so I will concentrate on these."
CIELO FILHO César (BRA), 3:10.34, a member of the silver medallist team in men's 4x100m freestyle relay:
"It was very hard. I mean before the race we had a chat and made a deal between us that everybody should try to swim around point three or point four because that would put us at three-ten, and it was going to be enough for a medal. We could manage to follow the plan. I think we were closer to the United States, so it was a good result for us, especially after not medalling in Rio last year. I think it's a great start for us and it showed the power of our team."
DOMINIK Kozma (HUN), a member of the bronze medallist team in men's 4x100m freestyle relay:
"They usually say if you get into the world championships final, everything can happen there. However, we couldn't imagine this for the first time, it is simply amazing. When we started swimming, we felt that it was going to be great and it does not matter how tired we were when we left the pool, we needed to cheer for the others. I do not really know how I will swim 200 metres after shouting so much... The audience is brilliant! We can hear them cheering even before entering the pool area. This gives us an unbelievably huge momentum."
LEDECKY Katie (USA), 3:31.72, a member of the gold medallist team in women's 4x100m freestyle relay:
"It was a good first day for USA. We are very happy with the result."
KROMOWIDJOJO Ranomi (NED), 3:32.64, a member of the bronze medallist team in women's 4x100m freestyle relay:
"We started with our young Kim Busch and she made a good job! She was really fast! We had the opinion that we all swim fast, so something can happen with the medals! Of course, the Swedish team started with Sara Sjoestrom and with a world record, so she was just too fast. When I was on, I said I just need to go and go, I cannot stop, and we can reach something!"
CAMPBELL Bronte (AUS), 3:32.01, a member of the silver medallist team in women's 4x100m freestyle relay:
"We are very happy. We are very pleased with that. It was a tough race, so we are very excited to come away with the silver medal. The whole team did a very good job. It was a fantastic atmosphere. It was amazing Hungary winning the bronze medal before us, so it was good to watch."
SJÖJSTRÖM Sarah (SWE), 3:33.94, started the women's 4x100 freestyle relay with championship record:
It was fun to lead our team with such a great time! I felt during the whole race that I am very fast. The plan was for today to let start our relay for the first place and it seems that I am in a good shape.
