Debonair chap collapses in race (4,8)

I believe the answer is:

ebor handicap

'race' is the definition.
(annual horse race)

'debonair chap collapses' is the wordplay.
'collapses' indicates an anagram.
'debonair'+'chap'='debonairchap'
'debonairchap' with letters rearranged gives 'EBOR HANDICAP'.

'in' is the link.
