Cycling in Yorkshire? (6)
I believe the answer is:
riding
I believe this clue is a double definition.
'cycling' is the first definition.
(riding a bike)
'in yorkshire?' is the second definition.
(one of three geographical divisions of Yorkshire)
(Other definitions for riding that I've seen before include "Sitting on and controlling the movements of a horse" , "Travelling by horse" , "Canadian constituency" , "Establishment teaching equestrian skills" , "Going cycling, perhaps" .)
