Spirited sprinting (7)
I believe the answer is:
dashing
This clue is a double definition.
'spirited' is the first definition.
('dashing' can be similar in meaning to 'spirited')
'sprinting' is the second definition.
('dash' can be a synonym of 'sprint')
(Other definitions for dashing that I've seen before include "Making haste" , "Swashbuckling" , "Striking" , "sprinter's talent?" , "sprinting" .)
