Premise: Usain Bolt . He also holds the world record as a part of the 4 × 100 metres relay . An eight-time Olympic gold medalist , Bolt won the 100 m , 200 m and 4 × 100 m relay at three consecutive Olympic Games , although he subsequently lost one of the gold medals ( as well as the world record set therein ) nine years after the fact due to teammate Nesta Carter 's disqualification for doping offences . Bolt improved upon his first 100 m world record of 9.69 with 9.58 seconds in 2009 -- the biggest improvement since the start of electronic timing . He has twice broken the 200 metres world record , setting 19.30 in 2008 and 19.19 in 2009 .
Hypothesis: There is a perosn that has won world records name Usain Bolt.
