Sees the place prepared for athletics event (12)
I believe the answer is:
steeplechase
'athletics event' is the definition.
'steeplechase' can be an answer for 'event' (steeplechase is a kind of event). I am not certain of the 'athletics' bit.
'sees the place prepared' is the wordplay.
'prepared' indicates anagramming the letters.
'sees'+'the'+'place'='seestheplace'
'seestheplace' is an anagram of 'STEEPLECHASE'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for steeplechase that I've seen before include "Horse race with ditches and hedges" , "Running event over hurdles and water jumps" , "Horse race with jumps and ditches" , "Non-flat horse race" , "run?" .)
