Usain Bolt, in lane five, takes to the front pretty much more the bend is finished and floats down the final straight.
He's a sea of tranquility in a storm of frantic legs and arms, strained necks and tight muscles. Simple.
Heat nine is upon us. Usain Bolt racing for a place in the 200m semi-final - he holds his finger over his mouth to shush the crowd, like the fastest teacher in the world - and off they go...
Usain Bolt takes a practice start and then applauds the crowd. There's an instant roar. The guy could sneeze and they'd love it.
Shame the venue is not packed.
Men's 200m heats
Easy peasy for LaShawn Merritt who is round in 20.15 seconds. Christophe Lemaitre is second to join him in the semi-finals.
Meanwhile, there's a massive whoop from the crowd as a certain Jamaican enters the arena...
Women's discus final
Image source, ReutersCroatia's Sandra Perkovic retains her Olympic discus title with a best throw of 69.21m.
Perkovic, who is unbeaten this year, had fouls in the first two rounds and her only legal throw in round three was good enough to secure gold.
France's Melina Robert-Michon threw a national record 66.73m to take the silver.
Cuba Denia Caballero, the 2015 world champion, got the bronze with 65.34m.
Badminton
A tough start for Langridge and Ellis who trail 11-4 at the midway stage of the first game.
A few huge smashes from Fu Haifeng who holds the world record at 206 mph - that's faster than Lewis Hamilton in his Mercedes.
Heat seven is done and dusted Nery Brenes of Costa Rica and Churandy Martina of the Netherlands are through - next up is the USA's LaShawn Merritt.
Men's 200m
With one more heat before Usain Bolt comes out for his 200m heat, there's a sneaky view of the great man in the waiting area, doing a little bit of... I want to say samba dancing. It may be jive.
Dancing's not my thing. Leave me alone.
It's remarkable that he knows whenever a camera is pointed at him. Unless he's constantly bonkers.
Men's 200m
Image source, ReutersGB's Adam Gemili after qualifying for the 200m semi-final: "I tried to run it as best as I could and not as hard as I could. I've qualified and l'm happy. The body is in a great place and I'm excited to compete with these guys."
200m
No alarms, no surprises.
Adam Gemili comes through alongside Jamaica's Nickel Ashmeade and well clear of the rest.
Gemili clocks 20.20 in second, five hundredths behind Ashmeade to go through.
GB's Gemili safely through to 200m semi-finals
Next up on the track, Great Britain's athletics skipper Adam Gemili.
His last season was crooked by injury.
He is up against Nickel Ashemeade of Jamaica in this heat who has the same season's best of 20.07.
These two should be the first two home. If not, 20.36 is the mark that would get you in as a fastest loser so far.
200m
United States' Justin Gatlin goes through, easing up about 40m before the line to dispense a bit of advice to Barbados' Ramon Gittens on his inside.
Gatlin is through but Gittens' time is not going to be enough as he comes third in a slow heat.
Justin Gatlin - jeered before the 100m final - is up next in the 200m heats.
He gets another mixed reception as his name is read out.
Badminton
Great Britain's Chis Langridge and Marcus Ellis are on court for their men's doubles semi-final against China's Fu Haifeng and Zhang Nan.
Victory would book their place in the final and confirm Britain's first Olympic badminton medal for 12 years.
A tough one though against the world number four pair who were both gold medalists at London 2012, Fu in the men's doubles and Zhang in the mixed.
Britain's world number 22 pair have beaten the pairs ranked third and eighth in the world already in the competition however...

Michael Conlan misses out on medal
Richie Woodhall
Former world champion on BBC TV
"I can't see how they've come to that decision. It wasn't a close contest at all. You can tell by the Russian's face.
"It's sad because we'll lose Conlan to the pro game now."
Michael Conlan misses out on a medal
Ireland's Michael Conlan has missed out on a medal in the boxing ring after losing a unanimous decision to Russia's Vladimir Nikitin in the 56kg bantamweight division.
It was a questionable decision in an all-action affair where Conlan was getting the better of the exchanges and opening a cut on the Russian in the second round.
However, the judges saw it differently as they favoured the work of the 2013 world silver medallist to give him a place in the semi-finals on Thursday.
