Quick answer
The 2026 Pan Pacific Swimming Championships were swum August 12 to 15 in Irvine, California. The United States topped the pool medal table with 19 gold and 51 medals, ahead of Australia (14 gold, 34 total) and Canada (3 gold, 13 total). Kate Douglass broke the world record in the 50 free (23.19), the U.S. mixed medley relay set a world record (3:36.70), and Summer McIntosh won the 400 IM in a championship record 4:28.01.
Pan Pacs is the main international long course meet of the summer for the United States, Australia, Canada and Japan. The 2026 edition, at the William Woollett Jr. Aquatics Center in Irvine, was fast: championship records fell in 32 of the 41 pool events.
Below you will find every champion with the winning time, the records, the medal table, and what stood out for American and Canadian swimmers. All times come from the official Omega results book, published by USA Swimming.
Where, when and how the meet works
- Dates: August 12 to 15, 2026 (pool events)
- Place: Irvine, California, long course (50 m)
- Format: heats in the morning, A and B finals at night. The 800 and 1500 free were timed finals, with the fastest heat swum in the evening session.
- Events: 34 individual events and 7 relays, including the mixed 4x100 medley.
The B final matters more than it looks. In the men's 100 free, American Chris Guiliano won the B final in 47.16. That was under the old championship record and faster than the A final silver (47.62), but it earned no medal. Jack Alexy's 47.14 in the A final is the record that stands.

What parents of age groupers can take from this
Most of the swimmers on these podiums raced age group meets in the same kinds of pools as your kids, and their progression is public. In Gophin you can open any of these swimmers and look back through their times by season: when they first broke a minute, how many seasons they plateaued, and where the big drops came.
The next step on the same pathway is the Junior Pan Pacs, swum a few days later in Vancouver. We covered it in 2026 Junior Pan Pacs results. If you want to see how an elite time translates to other events, World Aquatics points are the common scale.
