Overview
- Marrit Steenbergen broke the women's 100m freestyle world record in Rome with a 51.68 on Saturday, shaving three hundredths off Sarah Sjostrom's 2017 mark.
- Gretchen Walsh followed with a 23.55 in the 50m freestyle on Sunday at the same meet, eclipsing Kate Douglass's 23.59 from a U.S. Pro Swim Series race on June 19.
- Sarah Sjostrom has now lost two sprint world records this month, first the 50m and now the 100m, underscoring a quick turnover at the top of the events.
- Walsh and Douglass train together at the University of Virginia, and their recent leaps plus Steenbergen's surge reflect concentrated training depth reshaping the sprint pecking order.
- The fast times were posted at high-profile summer tune-up meets, a pattern that suggests more swimmers may push into low-52 and 51-second 100m territory and that favorites for upcoming championships will be reassessed.
