US 2026 National Championships and Pan Pacific Championships Set New Attendance Records at William Woollett Jr. Aquatics Center

The attendance figures for the 2026 U.S. National Championships and the 2026 Pan Pacific Championships have been officially released by USA Swimming, providing a clear picture of growing interest from the American sports community and the Pacific region. This event is not only a gathering of top athletes but also an opportunity for organizers to assess the effectiveness of facility utilization and the potential for the swimming industry to develop. According to updated data, a total of 18,701 participants attended the William Woollett Jr. Aquatics Center in Irvine, California, as part of the U.S. National Swimming Championships. Of these, 809 swimmers participated directly, along with hundreds of coaches, referees, and support staff. This number indicates stability and continued growth in domestic events, although compared to previous major events such as the 2026 Olympic Trials with over 285,000 spectators, it still reflects the need for select competitions specific to the domestic competition system.
