Usain Bolt: Eight-time Olympic champion's career in 9.58 charts

As the Jamaican prepares to retire after the World Championships in London, here are 9.58 reasons why he deserves to be called a legend, and how he achieved it.

He is the fastest runner in history. Bolt has set the past three world records at 100m, and it is nine years since he first broke it.
 

Bolt beat compatriot Asafa Powell's record of 9.74 seconds by clocking 9.72 in May 2008, then lowered it to 9.69 at the Beijing Olympics later that year.

At the 2009 World Championships in Berlin, he shaved more than a tenth of a second off his record, clocking 9.58 seconds.

Back in 1912, American Donald Lippincott ran 10.6 seconds in Stockholm to set the first time recognised by the sport's newly founded governing body, the IAAF.

Jim Hines, in 1968, was the first man to officially dip under 10 seconds, but it took almost a century for Lippincott's time to be bettered by a whole second - courtesy of Bolt.
