Although the world record is still 9.58 seconds which was run by Usain Bolt at 2009 World Championships in Athletics held in Berlin, Germany, Bolt became the first athlete to win a third successive Olympics 100m gold medal at 3 events (2008, 2012 and 2016).
Reacting to his victory, Bolt said he was trying to become immortal with all that speed.
"I am a living legend. Somebody said if I win these three gold medals I would be immortal and I kind of liked it. So I'm going to run with that one.
"I'm happy and I'm proud of myself. It wasn't perfect execution, but I'm proud of myself.
"I wanted to set myself apart from everybody else and this is the Olympics, I have to do it.
"I came to this Olympics to win three gold medals, to prove myself again as one of the greats."
