Muriel Gray is joined in East Anglia by father and son, Peter and Dan Snow to walk along the Boudicca Way.
The pair have been walking together since Peter took Dan up a Welsh mountain, when he was just 27 days old. They've since shared a love of history, sailed together across the Atlantic, and bickered occasionally over a map.
Series exploring the areas around our greatest battlefields.
