 Bolt then focused on attaining a gold medal in the 200 m event , aiming to emulate Carl Lewis ' double win in the 1984 Los Angeles Olympics . Michael Johnson felt that Bolt would easily win gold but believed that his own world record of 19 @.@ 32 s set at the 1996 Summer Olympics in Atlanta would remain intact at the Olympics . Bolt eased through the first and second rounds of the 200 m , jogging towards the end of his run both times . He won his semi @-@ final and progressed to the final as the favourite to win . Retired Jamaican sprinter Don Quarrie praised Bolt , saying he was confident that Johnson 's record could be beaten . The following day , at the final , he won Jamaica 's fourth gold of the Games , setting a new world and Olympic record of 19 @.@ 30 s . Johnson 's record fell despite the fact that Bolt was impeded by a 0 @.@ 9 m / s headwind . The feat made him the first sprinter since Quarrie to hold both 100 m and 200 m world records simultaneously and the first since the introduction of electronic timing . Furthermore , Bolt became the first sprinter to break both records at the same Olympics . Unlike in the 100 m final , Bolt sprinted hard all the way to the finishing line in the 200 m race , even dipping his chest to improve his time .
