Crossword Genius

Race often won by such effrontery (4)

Ross

I believe the answer is:

neck

I believe this is a double definition.

'race often won by such' is the first definition.
(to win by a neck is to win by a narrow margin)

'effrontery' is the second definition.
(neck can mean effrontery or impudence)

(Other definitions for neck that I've seen before include "Body part and the nerve to do something" , "It's risky to stick it out" , "top of bottle" , "Bottle part" , "jowl?" .)

I've seen this clue in The Times.
