Equestrian bathed in Olympic adoration (7)
I believe the answer is:
picador
'equestrian' is the definition.
(I know that picador is a type of equestrian)
'bathed in olympic adoration' is the wordplay.
'bathed in' says the answer is hidden in the clue.
'PICADOR' can be found hidden inside 'olympic adoration'.
(Other definitions for picador that I've seen before include "Horseman in bullring" , "The bullfighter who goads the animal" , "Mounted bullfighter with a lance" , "Animal killer" , "Riding bullfighter" .)
