She entered the 2009 IAAF World Athletics Final having won her last three races by a significant margin. Even taking this into account, Jeter surprised with one of the highlights of the final edition of the IAAF World Athletics Final. She won the 100 m race in Thessaloniki, Greece with a time of 10.67, to become the third fastest woman in history and set a championship record. This was the fastest run in twelve years; a time which had only been bettered by Marion Jones and Florence Griffith-Joyner, and 0.16 seconds faster than Jeter had ever run before. She ran even faster a week later at the Shanghai Golden Grand Prix, winning in 10.64 seconds (the fourth fastest time ever) to become the second fastest woman outright.
