The diving pool is still green. Biles led the Americans to team gold last week before claiming Olympic all-around gold.
And that's just this weekend.
It was not just that the history-making 100-meter men's sprint started at 10:25 p.m. local time. Or, at least, it did for 9.81 seconds.
Usain Bolt defended his 100m Olympic title easily as he won gold in a time of 9.81 seconds ahead of Justin Gatlin in Rio de Janeiro.
De Grasse also found his mom Beverley in the crowd. He climbed through the photographer's well so he could embrace random fans. It's that famous, arching, "To the World" pose that he debuted eight years ago in Beijing. He has essentially been the Michael Phelps of track, since the 2008 Olympics, only much more entertaining.
The Jamaican was introduced last, of course, to the adoring Theatre of Bolt, receiving rapturous applause, cheers and the thunderous chant of "Bolt, Bolt, Bolt".
Imagine, for a moment, if Gatlin had won. "So this is why he tells me to stop talking about retirement and just take it a year at a time". "Away from the track, he's a great guy, he's a cool guy, there is no rivalry between us".
And he almost did.
Gatlin had been widely booed as he entered the track, but at the end still grabbed the Stars and Stripes and draped it over his shoulders for his own victory lap.
The 6-foot-5 sprinter/celebrity overcame his typically slow unfurling from the blocks - he was second-to-last after the break - then churned his legs to gradually build up speed. That's where physics engages.
Jamaican Usain Bolt's historic hat-trick of Olympic 100 metres titles has drawn praise from the country's Prime Minister Andrew Holness. And then he turned on the jets and left Gatlin and De Grasse to fight for the leftovers. The race always took longer than the 100-meter in track, but there was the same kind of blurred drama: one trip down the mountain, every four years, fastest skier wins. The 9.81 was slower than London (9.63) or Beijing (9.69), and the margin of victory was smaller (.08 seconds compared to.12 and.20). Throw in two more Olympic and four world championship 4x100m relay golds and the world record in all three events and that is total and utter domination. It's about winning. It's about the triple-triple: golds in the 100, 200 and 4x100 relay in three straight Games.
"I felt really smooth, I knew if I ran through the line I probably would have ran the world record or close to it", said Bolt, who took gold ahead of Justin Gatlin and will go head-to-head with the two-time drug cheat over 200m as well. "Two more golds to go and I can sign off. Immortal".
Sunday, it was about something else, too.
"If you know where I came from, you would understand why I'm so hungry to get where I am now", Bromell said.
Van Niekerk finished 0.15 seconds faster than Johnson ran in 1999, setting a mark considered one of the nearly untouchable records in track.
How many gold medals can one gymnast collect at one Olympics? Before the Olympics, Bolt hadn't run a 100 since June 30, when he pulled out of Jamaica's national championships with injuries to his left hamstring.
At the Rio velodrome, Mark Cavendish of Britain tries to capture the Olympic medal that has long eluded him in the omnium. Media reported he tried to kill himself.
Then Bolt took care of the rest of the world.
When American sprinter Justin Gatlin was announced to the crowd at Olympic Stadium, the reaction was mixed, to put it kindly.
And the South African did it from the outside lane.
After Sunday's finals, the USA still tops medals table on 26 golds, while Britain and China are level on 15 gold medals with Britain placing second due to more silvers.
