Where to take off and dry sports kit (8)
I believe the answer is:
airstrip
'where to take off' is the definition.
(where an aircraft takes off)
'dry sports kit' is the wordplay.
'dry' becomes 'air' (airing is a kind of drying).
'sports kit' becomes 'strip' (eg strip can mean a football kit).
'air'+'strip'='AIRSTRIP'
'and' is the link.
(Other definitions for airstrip that I've seen before include "Simple runway" , "Small runway" , "possible starting place" , "Small flying field" , "(Unprepared) runway" .)
