Jamaican sprinting superstars Usain Bolt, Yohan Blake and Shelly-Ann Fraser-Pryce are part of a proud Olympic record that stretches back 50 years.
During the 1960s, Jamaican athletes were growing up through the prestigious high school 'Champs' before gaining scholarships in America to pursue their careers on the track.
Dennis Johnson, Jamaica's first 100 yards world record holder, had a dream of developing world class athletes at home and helped to establish a sprinting training programme.
