I own a 1:200,000 map of East Anglia (which includes neither Oxford nor London), and a 1:50,000 OS map which covers Cambridge, out to Newmarket and slightly beyond.

What I don't own is a conventient way of carrying them such that I can read them while cycling, but I hope that Ben Hayward's will have such a thing by Saturday.

I'd definitely go through the villages if cycling sociably, it's nice to be able to chat rather than just following single-file.
