Like small bed in racecourse? (5)
I believe the answer is:
ascot
'racecourse?' is the definition.
(British racecourse)
'like small bed' is the wordplay.
'like' becomes 'as'.
'small bed' becomes 'cot' (I've seen this before).
'as'+'cot'='ASCOT'
'in' is the link.
(Other definitions for ascot that I've seen before include "Royal race course" , "sporting event" , "Society race meeting" , "Royal Berkshire race-meeting (and fashion show!)" , "Place for meeting" .)
