Dash round prints (6)
I believe the answer is:
sprint
'dash' is the definition.
('sprint' can be a synonym of 'dash')
'round prints' is the wordplay.
'round' indicates an anagram.
'prints' anagrammed gives 'SPRINT'.
(Other definitions for sprint that I've seen before include "quick run" , "Rush" , "To make fast progress" , "Quick dash" , "Run quickly" .)
