Leisurely run (4)
I believe the answer is:
trot
'leisurely run' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for trot that I've seen before include "Slowish run, of horse or person" , "Go or walk briskly" , "Left-winger - move at a fair speed" , "Horse's gait faster than a walk" , "Not dead" .)
