In sprinting, Jamaicans had begun their domination of the 100 metres world record in 2005. Jamaica's Asafa Powell set the record in June 2005 and held it until May 2008, with times of 9.77 and 9.74 seconds respectively. However, at the 2008 Summer Olympics in Beijing, Jamaica's athletes reached heights by nearly doubling the country's total gold medal count and breaking the nation's record for the number of medals earned in a single game. Usain Bolt won three of Jamaica's six gold medals at Beijing, breaking an Olympic and world record in all three of the events in which he participated. Shelly-Ann Fraser led an unprecedented Jamaican sweep of the medals in the Women's 100 m.
