Sprinter's race (4)
I believe the answer is:
dash
'sprinter's race' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for dash that I've seen before include "Hurry; destroy (hopes)" , "Drop" , "instrument panel" , "Discourage - suggestion - hurry" , "Run quickly - little taste - hyphen" .)
