The 2026 Pan Pacific Championships kicked off with a bang, setting the stage for an exciting few days of swimming. The first finals session alone saw multiple Championship records fall, and the potential for more world records to be broken. The women's 50 fly was a highlight, with Gretchen Walsh and Kate Douglass dueling for the top spot. Walsh, a rising star in the sport, could seriously challenge the 50 fly world record. In the men's 50 fly, Ben Armbruster took the top seed, with Americans Van Mathias and Michael Andrew close behind. The women's 200 freestyle prelims were a close race, with Summer McIntosh qualifying fourth, behind Australian Lani Pallister, New Zealand's Erika Fairweather, and American Anna Peplowski. Luke Hobson picked up the third Championship record of the prelims session in the men's 200 freestyle, stopping the clock in 1:44.31. The women's 100 backstroke saw Regan Smith set a new meet record, and the men's 100 backstroke prelims were a close battle between Canada's Blake Tierney and American Will Modglin. The Americans dominated the women's 200 fly prelims, with Alex Shackell and Tess Howley earning the top seeds. Luca Urlando led the men's 200 fly prelims, with fellow American Carson Foster and Australian Harrison Turner close behind. The men's 800 freestyle is a timed final event, with Sam Short and Bobby Finke as the only favorites to win. Katie Ledecky is the top seed in the women's 1500 free, and while she has some races this week that could go to somebody else, this is not one of them. The final event of the session will be the mixed 4x100 medley relay, where Australia and the United States will battle for gold, with the full-strength United States likely to win and potentially break their own world record. The women's 50 butterfly, men's 50 butterfly, women's 200 freestyle, men's 200 freestyle, women's 100 backstroke, men's 100 backstroke, women's 200 butterfly, men's 200 butterfly, men's 800 freestyle, and women's 1500 freestyle are all set to be thrilling races, with the potential for new records and exciting performances. The 2026 Pan Pacific Championships are shaping up to be a spectacular event, and the first finals session has certainly set the bar high for the rest of the meet.
