Runs in place (5)
I believe the answer is:
idles
'runs in place' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for idles that I've seen before include "Avoids working" , "Spends time doing nothing" , "Lazes about, just ticks over" , "Does little, just ticks over" , "Lazes around" .)
