Race duo crashed in country (7)
I believe the answer is:
ecuador
'country' is the definition.
(Ecuador is an example)
'race duo crashed' is the wordplay.
'crashed' indicates anagramming the letters.
'race'+'duo'='raceduo'
'raceduo' is an anagram of 'ECUADOR'.
'in' acts as a link.
(Other definitions for ecuador that I've seen before include "South American republic" , "Is Cora due out in South America?" , "The Galapagos Islands are part of its territory" , "Country of the Galapagos Islands" , "Quito's nation" .)
