Bolt competed in his final Jamaican High School Championships in 2003. He broke the 200 m and 400 m records with times of 20.25 s and 45.35 s, respectively. Bolt's runs were a significant improvement upon the previous records, beating the 200 m best by more than half a second and the 400 m record by almost a second. While Bolt improved upon the 200 m time three months later, setting the still-standing World youth best at the 2003 Pan American Junior Championships. The 400 m time remains No. 6 on the all-time youth list, surpassed only once since, by future Olympic champion Kirani James.
