After seven years out of competitive swimming, Torres began to train for an Olympic comeback in 1999 under the guidance of coach Richard Quick. She won five medals at the 2000 Summer Olympics in Sydney, but saved her best for two of the major relay events of the U.S. Olympic women's team. She swam the second leg for the winning U.S. women's team in final of the 4×100-meter freestyle relay that included Amy Van Dyken, Courtney Shealy, and Jenny Thompson. Torres won a second gold medal for anchoring the winning U.S. team in the 4×100-meter medley relay, together with teammates B.J. Bedford, Megan Quann, and Jenny Thompson in the final. Individually, Torres also earned bronze medals – her first Olympic medals in individual events – in each of the 50-meter freestyle, the 100-meter butterfly and the 100-meter freestyle, tying teammate and rival Jenny Thompson for third place in the last event. At 33 years old, Torres became the oldest woman to win an Olympic medal in swimming. She was the oldest member of the U.S. Olympic swim team, but won more medals (five) than any other U.S. team member.
