No prob, Jags.

If you haven't used an A to Z map before, they are designed for driving rather than walking which means they look pretty empty compared to OS stuff - no grid lines, for instance, no power lines or streams and forests / woods aren't marked. It makes them a lot cleaner and clearer if you are planning on getting somewhere.
We used them years ago to plan a route to Lands End and they cover pretty much everything needed for cycling. Use one for planning the route, alongside something like bikehike.co.uk to check the gradients, and the paper map is all you need to take with you.
I've just realised that mine are 20 years old, so ordered a couple of new ones.
