Bloke runs for shelter (5)
I believe the answer is:
cover
'shelter' is the definition.
(thesaurus)
'bloke runs' is the wordplay.
'bloke' becomes 'cove' (I've seen this in other clues).
'runs' becomes 'r' (cricket abbreviation).
'cove'+'r'='COVER'
'for' is the link.
(Other definitions for cover that I've seen before include "Conceal a thing or fact - . . . . . up" , "Sit on - suffice for" , "Conceal, screen" , "the point of cricket" , "(Put) lid (on) - fielding position - insurance" .)
