(CNN) - It's an end of an era for global track and field.
Jamaican sprinting legend Usain Bolt plans to run his final races at the World Athletics Championships in London, which begins Friday.
Bolt plans to run his last individual race of his career, in the final of the 100 meters on Saturday.
He's then expected to run on Jamaica's 4x100-meter relay a week later, which will be his final appearance on any track.
Bolt will retire as one of the most decorated stars in track history.
He's the current world record holder in both the 100 and 200 meters.
He's also the first man to win three Olympic golds in the 100 meters.
Bolt has also captured 11 golds and two silvers at the World Athletics Championships.
