A chap in kilts at the racecourse (5)
I believe the answer is:
ascot
'the racecourse' is the definition.
(British racecourse)
'a chap' is the wordplay.
'chap' becomes 'scot' ().
'a'+'scot'='ASCOT'
'in kilts at' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for ascot that I've seen before include "Berkshire race course" , "Royal race meeting venue" , "track" , "racing centre" , "Racecourse, home to the Gold Cup since 1807" .)
