Beginning with her first Olympic win in 2008, Fraser-Pryce had been at the forefront of a booming sprint rivalry between Jamaica and the United States. At the Beijing Olympics, Jamaica captured five of a possible six gold medals in the sprints, with Fraser-Pryce and Campbell-Brown winning the 100 m and 200 m respectively, and Usain Bolt dominating the men's 100 m, 200 m, and 4 × 100 m relay. Jamaica's success continued through the 2009 and 2011 World Championships, highlighted by Bolt's record-breaking performances at each event. Fraser-Pryce's career dip in 2010 and 2011 saw U.S. sprinter Carmelita Jeter rising to prominence in the 100 m, becoming the second fastest woman of all time (at the time) and clinching the world title in 2011. Fraser-Pryce later described Jeter as the toughest rival she faced throughout her career.
