On a night where Usain Bolt was expected to take centre stage, the Jamaican sprinter was somewhat upstaged by a fellow track athlete.
Despite clocking a hugely impressive 9.81 and seeing off challenges from Justin Gatlin and countryman Yohan Blake to claim a third successive Olympic gold in the 100m, it was Wayde van Niekerk's win in the 400m that stole headlines.
Not only did the South African win gold from the dreaded eighth lane, but he also smashed Michael Johnson's 17-year-old record by 0.15 seconds (43.03).

In the aftermath of Van Neikerk's historic victory, Bolt lauded the 24-year-old and trolled Johnson in the process.
He told reporters: "For me, it's brilliant. When he came to Jamaica, I said to him 'listen, I’m talking to my coach, you're probably the only person who can break the world record because you've got the speed and you've got the strength'.
"He did great, I'm proud of him. There's no words. I know Michael Johnson's not happy, though."
Bolt has since followed up those comments by challenging Van Niekerk to a 300m race - how epic would that be?
The Olympic legend said, per The Sun: "I'd really like to compete against him at 300m.
"He's very fast and keeps on going. To me, I wasn't really surprised he got it. I thought 'wow, that’s just brilliant'.
"That would be a good one over 300m. I'd really like to compete against him."
And in an attempt to convince Van Niekerk of racing him, Bolt also claimed he could have broken Johnson's 400m record if he had trained for it.
"If I was running the 400m I could break the world record," the 29-year-old added. "If it was up to my coach I would be running it now but I don't want to.
"I have the speed and stamina so there was already that possibility (to break the record) if I did the 400m."
Make it happen, Usain.
