In the women's 100 m freestyle, Ryu missed out the semifinals by a hundredth of a second (0.01) in 55.02, but offered a second chance, after Germany's Franziska van Almsick scratched the event to focus on German relay duty in the 800 m freestyle relay. Ryu failed to qualify for the final, as she finished her semifinal run with a second slowest time of 55.85 seconds. In her final event, 50 m freestyle, Ryu raced to fifth place in heat seven by 0.06 of a second behind Venezuela's Arlene Semeco in 26.26. Unlike her previous individual event, Ryu failed to advance into the semifinals, as she placed twenty-sixth out of 75 swimmers in the preliminary heats. She also tied her position with Puerto Rico's Vanessa García.
