A biking Brit explains how easy it is to find evidence of the people from centuries past along the backroads of England and Scotland. And a pair of British tour guides get us ready to visit England's magnificent and historically important cathedrals, from Canterbury to York Minster.

• Graham Robb's latest work is "The Discovery of Britain: An Accidental History."
