4D.. Not after any records, but think it may appeal more on sponsorship front if done in one go.
you do have a point about missing some wonderful roads, fortunately i've done nearly all the route before on various rides, normally trying to avoid motorways.
I've got the trip to and from each end to enjoy the more scenic roads.
KB sure i'll sponsor you, but just to be evil, £10 if you do it with the dishy guy and £20 if you do it alone or with some horror with bad breath
Its great fun, i'm sure you'll love it. Good on yer.
