Just a quick point here, that the start and end points are about 30 miles apart, so ifone vehicle is left at the start, there is about a 60 mile round trip - probably better to meet up "nearer home" so to speak.
Good initiative Steve.
Oh, we won't actually be off-roading as we will always be on a road (a byway that legally permits motorised vehicles) - just that these byways don't have a tarmac'd surface.
