Woman or man cycling (5)
I believe the answer is:
norma
'woman' is the definition.
'or man cycling' is the wordplay.
'cycling' indicates an anagram.
'or'+'man'='orman'
'orman' with letters rearranged gives 'NORMA'.
(Other definitions for norma that I've seen before include "Outdoor function" , "name for Monroe" , "Operatic lady round the manor" , "Manor (anag.)" , "Girl" .)
