It is that point in the summer when all of the competitions to qualify for the World Aquatics Championships are over, and now it’s just the wait until the meet starts. This year’s meet, the 22nd of these World Championships, will be held in Singapore after initially being awarded to Kazan, Russia, from where it was moved in response to their invasion of Ukraine. The event kicks off with Water polo on the 11th of July, with the pool swimming starting on the 27th of July and running through the 3rd of August.

As that date draws closer, we will preview all 42 of the pool events that are set to take place. From sprint freestyle to mixed relays to the newly added Olympic events, the 50s of butterfly, backstroke, and breaststroke, we’re covering it all. Check in regularly so you don’t miss any of our event-by-event coverage.

Below is the index for the previews, with a table for men’s, women’s, and mixed events. As previews go up, links and medalists will be added. Don’t miss our projected medal table at the bottom, which will update with each preview.

Marchand does not swim the 200 fly so…?

Finley will not win against the OW guys. I do not see him any medal chance. Hobson is the only medal hope for US male team. I do not think male team will win any relay against the Russians.

Lol, the men have plenty of gold medal chances. I’m assuming you’re talking about Finke? And the same open water guys he’s consistently beaten in the 1500? Not to mention, with Marchand not swimming the 200 fly, Urlando is likely the favorite, Aikins has a shot in the 200 back, they’re massive favorites in the men’s 4×1 free relay, and co-favorites with the Brits in the 4×2. Russia won’t be on the podium or beat the US in any relay with the possible exception of the men’s medley.

For the first time in a long time Australia may realistically miss top 5…

C’mon do the women’s 400 and 800 free! Give us time to fight in the comments before the meet starts.

Sounds like Scott ceded the spot. We’re working to confirm it.
