Quickly produce ladder, going where? (3,2)
I believe the answer is:
run up
'quickly produce' is the definition.
'ladder going where?' is the wordplay.
'ladder' becomes 'run' ('run' can be a synonym of 'ladder').
'going where?' becomes 'up' (I can't justify this - if you can you should believe this answer much more).
'run'+'up'='RUN-UP'
(Other definitions for run up that I've seen before include "Bowling approach" , "Make, arrive, quickly" , "Hoist" , "Incur" , "Illingworth had a short one" .)
