Runs without moving (5)
I believe the answer is:
idles
'runs without moving' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for idles that I've seen before include "Does little, just ticks over" , "Avoids working" , "Lazes around" , "Lazes about, just ticks over" , "Wastes time" .)
