Month for walking? (5)
I believe the answer is:
march
This clue is a double definition.
'month' is the first definition.
(March is an example)
'walking?' is the second definition.
(march is a kind of walking)
'for' is the link.
(Other definitions for march that I've seen before include "Month - advance in step" , "Walk smartly" , "Moving demonstration" , "Walk in a resolute manner" , "demo" .)
