Park began the 2004 Summer Olympics in Athens with a new women's world record for the preliminary 72-arrow ranking round, scoring 682 points (from a maximum of 720) to surpass the previous best of 679 set by Italy's Natalia Valeeva three months earlier. With teammates Lee Sung-jin and Yun Mi-jin she also set a new world record for the women's team event over 216 arrows, the three scoring a combined total of 2,030 points from a maximum of 2,160. Because the ranking round took place prior to the opening ceremony, neither score was classified as a new Olympic record.
