Arrange time for Olympic event (8)
I believe the answer is:
dressage
'olympic event' is the definition.
(I've seen this before)
'arrange time' is the wordplay.
'arrange' becomes 'dress' (dressing is a kind of arranging).
'time' becomes 'age' (an age is a period of time).
'dress'+'age'='DRESSAGE'
'for' is the link.
(Other definitions for dressage that I've seen before include "Equestrian sport of manoeuvring" , "equestrian activity" , "Mounted training" , "Art of training horses" , "Method of training horses to do manoeuvres" .)
