In general, time standards were generally faster than those at the 2023 U.S. Nationals, the U.S.’s final selection competition for the World Championships. This was particularly noticeable in the men’s competition, where LCM time standards became faster in all events except the 200m butterfly. For the women, the time standards were only faster in 5 of the 14 disciplines: 50 free, 200 free, 800 free, 100 breast and 100 fly. Most of the women’s time standards either stayed exactly the same or slowed down by just a few tenths of a second.
