Land trainer awkwardly (7)
I believe the answer is:
terrain
'land' is the definition.
(terrain is land or territory)
'trainer awkwardly' is the wordplay.
'awkwardly' indicates an anagram.
'trainer' is an anagram of 'TERRAIN'.
(Other definitions for terrain that I've seen before include "Type of countryside" , "Landscape" , "(Type of) ground" , "Land (viewed tactically)" , "Land (as base for action)" .)
