Barred from gym, stripped after naked run (7)
I believe the answer is:
streaky
'barred' is the definition.
(thesaurus)
'gym stripped after naked run' is the wordplay.
'stripped' says to take the centre (outside letters removed).
'after' says to put letters next to each other.
'naked run' becomes 'streak' (streaking can mean running without clothes on).
The middle of 'gym' is 'y'.
'y' put after 'streak' is 'STREAKY'.
'from' is the link.
(Other definitions for streaky that I've seen before include "sort of bacon" , "Like some bacon" , "of uneven quality" , "Having lines of differing colours" , "particular bacon?" .)
