Usain Bolt Now the First Athlete To Win Three Olympic 100m
Jamaica's Usain Bolt became the first athlete to win three Olympic 100m titles by beating American Justin Gatlin to gold at Rio 2016.
Bolt, 29, ran 9.81 seconds in his final Olympics to replicate his success at Beijing 2008 and London 2012.
Gatlin, twice banned for doping offences, finished 0.08 seconds behind Bolt to take silver.
"Somebody said I can become immortal. Two more medals to go and I can sign off. Immortal," said Bolt.
Canada's Andre de Grasse took bronze in a personal best of 9.91, ahead of Bolt's Jamaican team-mate Yohan Blake.
There was no British interest in Sunday's showpiece as CJ Ujah and James Dasaolu were eliminated in the semi-finals.
Bolt remains on target to leave Rio with a third successive Olympic treble, and a ninth gold, having won the 100m, 200m and 4x100m relay titles in 2008 and 2012.
"It wasn't perfect today but I got it done and I'm pretty proud of what I've achieved - nobody else has done it or even attempted it," he added.
"I expected to go faster, but I'm happy that I won. I did what I had to."
Bolt was slower out of the blocks than 34-year-old Gatlin, who was aiming to regain the title he won at Athens 2004.
But he surged through from 60 metres to pass Gatlin and comfortably win his seventh Olympic gold.
Bolt received a hero's reception as he walked out into Rio's Olympic Stadium before the race, and the crowd chanted his name after his victory.
"It wasn't about the time, it was just about winning the gold and going out on top," said Michael Johnson, four-time Olympic champion and BBC Sport analyst.
The world record holder, who said in February he would retire from athletics after the 2017 World Championships, competes in qualifying for the men's 200 on Tuesday, with the 4x100m relay beginning on Friday.
|Bolt's major 100m wins|
|2008 Olympic Games, Beijing||9.69 - world record|
|2009 World Championships, Berlin||9.58 - world record|
|2012 Olympic Games, London||9.63 - Olympic record|
|2013 World Championships, Moscow||9.77|
|2015 World Championships, Beijing||9.79|
|2016 Olympic Games, Rio||9.81|
Bolt showed an expectant Rio crowd he was in great shape by clocking a season's best 9.86 as he cantered to victory in his semi-final.
And the sport's greatest showman produced an even better run when it really mattered to send the Olympic Stadium into raptures.
"After the semi-final I felt extremely good," Bolt added.
"I wanted to run faster but with the turnaround time, we normally have two hours, but we had one hour 20 minutes, it was challenging.
"This is what we train for. I told you guys I was going to do it. Stay tuned, two more to go."
