Sarah Sjostrom's long-standing 100m freestyle world record is increasingly at risk as new talent emerges in women's swimming. Recently, Anna Moesch, a 20-year-old swimmer from the University of Virginia, clocked a remarkable 51.94 seconds at the AP Race London International, marking only the third sub-52 swim in history. Shortly after, Dutch swimmer Marrit Steenbergen surpassed Moesch with a time of 51.86 seconds during the Mare Nostrum series in Canet, France. Sjostrom's record of 51.71 seconds, set at the 2017 World Championships, now faces serious competition. Moesch's rise is particularly significant for U.S. swimming, which has struggled against Australia in the Olympic 4x100 relays. As Sjostrom prepares for the European Championships in Paris this July-August, the competition intensifies, with both Moesch and Steenbergen setting new benchmarks in the sport.
