Three and half weeks. Three hundred miles. I saw roaring arterial highway and silent lanes, candlelit cathedrals and angry men in bad pubs. The Britain of 1936 was a land of beef paste sandwiches and drill halls. Now we are nation of vaping and nail salons, pulled pork and salted caramel. In the autumn of 1936, some 200 men from the Tyneside town of Jarrow marched 300 miles to London in protest against the destruction of their towns and industries. Precisely 80 years on, Stuart Maconie, walks from north to south retracing the route of the emblematic Jarrow Crusade. Travelling down the country's spine, Maconie moves through a land that is, in some ways, very much the same as the England of the 30s with its political turbulence, austerity, north/south divide, food banks and of course, football mania. Yet in other ways, it is completely unrecognisable. Maconie visits the great cities as well as the sleepy hamlets, quiet lanes and roaring motorways. He meets those with stories to tell and whose voices build a funny, complex and entertaining tale of Britain, then and now.
