Flashing lights, big entrances, huge excitement.
4x100m relay finals were made for Saturday nights.
No Dina Asher-Smith for GB - but there's certainly still a medal hope here behind the expected titanic battle at the front of the race between USA and Jamaica.
But who is going to deliver the big finish on day eight?

The Great Britain quartet mean business. These girls train together. They work together. They'll do their absolute best.

A reminder the British quartet is Asha Philip, Imani-Lara Lansiquot, Bianca Williams, Daryll Neita.
But can they hold off 100m champion Sha'Carri Richardson and 200m champion Shericka Jackson?

Athens 2000 Olympic heptathlon gold medallist on BBC TV
Honestly, I'm confident because the girls do train so well together. When they come together for the relay they put in the hours. They practise. They gel which I think is really important. The comradery between them is so good.
They expect. We can sit there and say hope we get medals. They want it. They're hungry for this and they know they can be on the podium.

Colin Jackson
Two-time world 110m hurdles champion on BBC TV
The British team were spot on. They did a tremendous job.
That race really was so dominant down the back straight. You had the biggest hitters Marcel Jacobs, Fred Curley tearing down the back straight with our own Zharnel Hughes.

I don't think you can fault the British team. I think they ran really well.

Michael Johnson
Four-time Olympic gold medallist athlete on BBC TV
A lot of these teams didn't have athletes in the open 100m or open 200m so they've had a lot more time to actually spend working on those baton exchanges where you can make up a lot of time versus the teams that have a foot speed advantage.
Men's 4x100m relay final
There's so much swagger on track right now. The fastest men in the world are ready to dance.
Men's 4x100m relay final
Great Britain are by no means the favourites but the arrival of Zharnel Hughes makes them contenders.
An American win would be a hat-trick of golds for Noah Lyles of course.
