Turned up to run clubs perhaps as hobby (7)
I believe the answer is:
pursuit
'hobby' is the definition.
(I know that hobby can be written as pursuit)
'turned up to run clubs perhaps' is the wordplay.
'turned' says the letters should be written backwards.
'to run' becomes 'r' (cricket abbreviation).
'clubs perhaps' becomes 'suit' (clubs is a playing card suit).
'up' reversed gives 'pu'.
'pu'+'r'+'suit'='PURSUIT'
'as' acts as a link.
(Other definitions for pursuit that I've seen before include "The chase or the occupation" , "courting?" , "Hobby" , "An activity not entirely innocent" , "Interest" .)
