Boring hiker? (10)
I believe the answer is:
pedestrian
This clue is a double definition.
'boring' is the first definition.
(I've seen this before)
'hiker?' is the second definition.
(I know that hiker is a type of pedestrian)
(Other definitions for pedestrian that I've seen before include "lacking inspiration" , "flat" , "Unimaginative" , "lame" , "Dull, uninspired" .)
