Gretchen Walsh breaks women’s 50-meter freestyle world record in Rome

Gretchen Walsh swam 23.55 seconds to break the women’s 50-meter freestyle world record at the 62nd Sette Colli Trophy in Rome, shaving 0.04 off Kate Douglass’s mark. The swim came on the final day of the June 26-28 meet at Foro Italico and left Sarah Sjostrom second in 23.86. Walsh’s performance followed a 24.51 in the 50 butterfly two days earlier, the second-fastest time ever in that event.

The record changed hands twice in nine days. Douglass, Walsh’s former University of Virginia teammate and current training partner, had gone 23.59 in Indianapolis on June 19, trimming Sjostrom’s 23.61, which had stood since July 29, 2023. Walsh’s latest swim turned that brief reset into another turnover, with the event’s standard falling again before a week and a half had passed.

Virginia said Walsh’s effort was the 100th American record set by Cavaliers athletes in the last five years, a number that puts the school at the center of U.S. women’s sprint swimming. World Aquatics lists Walsh as the long-course 100 butterfly world record holder at 54.33 and the short-course 50 freestyle record holder, and she won two relay gold medals at the 2024 Paris Olympics. Those marks make Walsh more than a one-event threat; she is carrying world-class speed across multiple sprint disciplines.

The Rome result also showed how compressed the top of the women’s sprint field has become. Sjostrom, long one of the event’s defining figures, was still fast enough for second place in 23.86, while Walsh and Douglass are now trading records from the same training ecosystem. With the fastest times moving by hundredths instead of tenths, the 50 freestyle has become a race where a single meet can reset the standard twice.
