Since around 2006, Jamaica has supplied many of the world's fastest sprinters. Some have used genetics to explain the Jamaican dominance in sprinting, some credit the Jamaican environment, while others believe that it is the result of rampant cheating in the form of Performance Enhancing Drugs (PEDs). At the center of this debate is Usain Bolt, first recognized when he became the youngest gold medalist ever at the 2002 Junior World Championships. After establishing himself as a professional sprinter, Bolt won 17 of his 18 races between 2007 and 2016, capturing 17 gold medals and setting multiple world records. Since Bolt wins races against athletes known to have taken PEDs, some wonder if Bolt became the world's fastest man by taking PEDs himself.
