Race prints round (6)
I believe the answer is:
sprint
'race' is the definition.
(I've seen this before)
'prints round' is the wordplay.
'round' is an anagram indicator.
'prints' is an anagram of 'SPRINT'.
(Other definitions for sprint that I've seen before include "Rush" , "To make fast progress" , "Quick dash" , "quick run" , "Short race at full speed" .)
