Where: WCH Arena, Singapore.

+ How it's decided.
The World Championship was inaugurated as early as 10 July and also includes water polo, synchronized swimming, diving and open water swimming.
Pool swimming is decided in long course (50-meter pool) which is the major event in swimming and also applies to the Olympic Games.
+ Hopes for a record festival.
Canadian 18-year-old Summer McIntosh (400 meters freestyle, 200 and 400 meters medley), American Gretchen Walsh (twice on 100 meters butterfly), and Katie Ledecky (800 meters freestyle) and Lukas Märtens (400 meters freestyle in Stockholm) have all set world records this year.
So there's a huge chance they'll be even sharper in Singapore.
And don't forget that Léon Marchand, who won four Olympic gold medals on home soil in Paris, is also swimming in Singapore.
+ New prodigy: Chinese 12-year-old.
Swimming has had plenty of prodigies over the years. In Singapore, the world will get to know a new star: Chinese 12-year-old Yu Zidi. At the Chinese championships in May, she made the best run on 200 meters medley (2.10,63) that any 12-year-old has made so far in the world, among both girls and boys. The time she then made on 200 meters butterfly would have been enough for a fourth place in the Paris Olympic Games last year.
Yu's results have given her a dispensation to the World Championship, where she is expected to compete on 200 and 400 medley and 200 meters butterfly.
+ Took over from Russia.
Actually, this year's World Championship was supposed to be decided in Kazan, but Russia was stripped of the championship by the International Swimming Federation after the offensive war against Ukraine began in 2022. Instead, the arrangement went to Singapore and thus the World Championship is held for the first time in Southeast Asia.
Due to the pandemic that disrupted the championship schedule, this is the fourth year in a row that the World Championship in long course is decided. Normally, it's every other year, but now we're back on track after postponed and moved championships, and the next long course World Championship after this will be in Budapest 2027.
+ Stars who have quit.
Emma McKeon, Australia, put a period to her brilliant career after the Olympic Games in Paris where she won three medals. With six gold, three silver and five bronze in her career, she is Australia's most successful Olympian in history.
Hungarian "iron lady" Katinka Hosszu, Tatjana Smith, South Africa, and Maggie MacNeil, Canada, are other profiles who have hung up their swimsuits.
Among Swedish profiles, Michelle Coleman has said goodbye, while sprinter Björn Seeliger has taken a sabbatical year.
