Gallop or canter (4)
I believe the answer is:
gait
This clue is a double definition.
'gallop' is the first definition.
(thesaurus)
'canter' is the second definition.
(I've seen this in another clue)
(Other definitions for gait that I've seen before include "Bearing" , "Way of walking sounds like way of entry" , "Manner of walking or running" , "Style of movement" , "Carriage" .)
