Bowman's sport (7)
I believe the answer is:
archery
'bowman's sport' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for archery that I've seen before include "The sport of bowmen" , "Bowman's sport" , "Target sport - Olympic event in from 1900-08, in 1920 and since 1972" , "Arrow-shooting" , "Sport of the bowman" .)
