Mopes around the course (5)
I believe the answer is:
epsom
'the course' is the definition.
(I've seen this before)
'mopes around' is the wordplay.
'around' is an anagram indicator.
'mopes' is an anagram of 'EPSOM'.
(Other definitions for epsom that I've seen before include "place for racing" , "Surrey racecourse" , "English town, of course?" , "Town with racecourse" , "Poems about English Derby venue" .)
