Cheat for each run (7)
I believe the answer is:
scamper
'run' is the definition.
(scampering is a kind of running)
'cheat for each' is the wordplay.
'cheat' becomes 'scam' (scam is a kind of cheat).
'for each' becomes 'per' (I've seen this before).
'scam'+'per'='SCAMPER'
(Other definitions for scamper that I've seen before include "Run quickly and lightly" , "Run about briskly" , "Run around" , "Beetle" , "Run with quick light steps" .)
