Run – and hide (4)
I believe the answer is:
pelt
I believe this clue is a double definition.
'run' is the first definition.
(I know that run can be written as pelt)
'hide' is the second definition.
(I know that hide can be written as pelt)
'and' is the link.
(Other definitions for pelt that I've seen before include "Run fast - hide - pepper" , "Rain cats and dogs" , "Subject to bombardment" , "Hide; rain" , "Skin; run fast" .)
