If a horse-racing meeting requires military precision when it comes to its planning, what must go into a race meeting that doubles up as a gig?
Especially when the area used for the winners’ enclosure and parade ring is the one you want to use a dancefloor on which thousands can watch top DJs on the decks.
That’s the quandary that staff at Goodwood face three times a year when they follow their Friday-night racing fixtures with 90-minute sets that get the crowd dancing.
What’s more, they have a shade under half an hour between the moment when the horses from the final race are safely away from the area and the moment the headline acts take centre stage.
Those who have been to one of the events will know it’s an impressive transformation - but if you’ve not seen it for yourself, we can help.
Don’t worry - you don’t need to sit through a 30-minute video: our time-lapse video at the top of this story shows the operations team complete the job in under four minutes.
It’s impressive stuff at any speed, as those with Goodwood tickets to see Andy Cato of Groove Armada tonight (June 14) or Radio 1 and 2 legend Trevor Nelson next Friday (June 21) will see.
This footage was filmed before the recent Rudimental set, so if you were there, see if you can spot yourself.
