Loud race developed into travesty (5)
I believe the answer is:
farce
'travesty' is the definition.
(synonyms)
'loud race developed' is the wordplay.
'loud' becomes 'f' (short for forte - 'loud' in music).
'developed' indicates an anagram.
'race' anagrammed gives 'arce'.
'f'+'arce'='FARCE'
'into' is the link.
(Other definitions for farce that I've seen before include "Absurdity" , "Absurd event; comedy" , "Absurd drama" , "Ludicrous stage show" , "Absurd proceedings, perhaps in play" .)
