I know they are not real walks (start from a pub, eat lunch at a pub and finish up at a pub in the afternoon, maybe pass a pub or two on the way), but they have a lot of history.
A few friends are thinking of heading off to the UK next year to do the Offa's Dyke Path and maybe also walk the length of Hadrian's Wall.

Anyone have any experience with these tracks?
