Weinstein was the #5 seed in the 400 freestyle with an entry time of a 4:00.05 that she swam at last month’s US Summer Nationals. That swim also marked a personal best for Weinstein as she became the #7 performer all-time with the swim. Weinstein has shown great progress in the 400 free this season as she entered the summer with a lifetime best of a 4:04.54 from March 2024. Today’s race was expected to be her senior international debut in the event.
With Weinstein not swimming the 400 free, this leaves Katie Ledecky as the lone swimmer for the US in the event. Ledecky is the #2 seed (3:56.81), sitting only behind Summer McIntosh of Canada who swam to a World Record 3:54.18 last month.
Weinstein is also slated to swim in the 200 free (#3 seed) and 800 free (#7 seed) later in the meet and is projected to be a member of the US Women’s 4×200 free relay as she won the 200 free at US Summer Nationals. She originally was scheduled to race in the 10k open water competition but withdrew and was replaced by Mariah Denigan.
