Saturday saw the 'Race of the Games' contested in the women's 100 metres at Tokyo 2020.
In an absolute thriller it was Elaine Thompson-Herah who defended the title she won at Rio 2016, doing so in a sensational Olympic-record time of 10.61 seconds.
Our reporter in Tokyo, Peter Hanson, was lucky enough to be in the stadium to witness it happen.
For that and more, read on in our latest Daily Diary.
ELAINE-THOMPSON WOWS... AND SO DOES THE LIGHT SHOW
Never has the saying blink and you'll miss it been more apt in my life than watching the women's 100m final.
Man alive these women are rapid. None more so than Thompson-Herah. You can't help but be awed at the brilliance of her display. It has not been the easiest five years for the Jamaican but no doubt the gruelling hours spent training will now all be worth it.
For me, what was just as impressive was what preceded the race...
Darkness descended...then an engrossing LED light show started on the track, before finally displaying the names of each of the athletes...some people (me) are easily impressed.
CATCHING THE Z'S IN THE MEDIA ROOM?
It's a real privilege to be covering these Games, don't get me wrong…
But it is a bit of a mental marathon. The days are long, it's warm and humid here most of the time, and the quality and length of sleep are both poor.
Which is why I was totally sympathetic when I read a Tweet from a USA Today journalist who posted: "The reporter next to me in the media workroom just closed his eyes, lowered his head and fell dead asleep, still sitting up, with a half-written story on his screen. The Olympics, man. It's a grind."
I myself have been catching a few naps on the 30-minute rides on the shuttle buses…gotta get them Zs where you can folks!

JAPAN SWING FOR THE FENCES TO BREAK NEW GROUND
There may have been a fair bit on angst regarding the Games from the people of Japan.
But the home athletes have certainly done their part to try and create a feel-good factor.
Take the men's epee team, who on Friday had become the first non-European nation to win Olympic gold. In the process, Japan moved to 17 gold medals – their most a single Games.
Ranked as one of the two bottom nations, Japan had to get through the prelims to even compete.
"I don't want people to say that this is by chance," Masaru Yamada said. "I want to win another gold in the next competition."
ADAM HOPES TO INSPIRE AFTER THREE-PEAT(Y)
Adam Peaty entered Tokyo 2020 as a near shoo-in to win gold in the men's 100m breaststroke, which he did earlier in the Games.
On Saturday, he became a three-time Olympic champion as Team GB won gold in the 4x100m medley. Afterwards, Peaty had an inspiring message for the next generation.
"There's no point in British swimming being in such a great position if we're not going to inspire the next team to do it," he said.
"It's absolutely incredible. I never thought that one day I'd be a three-time gold medallist at the Olympics. It's a fun event and that's what sport needs. It needs to be fun."
