Ran nude around church, showing stamina (9)
I believe the answer is:
endurance
'stamina' is the definition.
(thesaurus)
'ran nude around church' is the wordplay.
'around' indicates anagramming the letters.
'church' becomes 'ce' (abbreviation for Church of England).
'ran'+'nude'='rannude'
'rannude' anagrammed gives 'enduran'.
'enduran'+'ce'='ENDURANCE'
'showing' acts as a link.
(Other definitions for endurance that I've seen before include "Patient suffering" , "ship bound for the Antarctic" , "Fortitude" , "Lasting quality" , "Ability to withstand prolonged hardship" .)
