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.

Don’t worry - you don’t need to sit through a 30-minute show: our time-lapse video at the top of this story shows the operations team complete the job in under four minutes.

This footage was filmed before the recent Rudimental set, so if you were there, see if you can spot yourself.
