It’s early in the morning. The clouds are low, there’s a chill in the air, the birds are singing. I’m walking out of the Tuscan town of Sarzana with the Frenchman Hervé de Lantivy, his crutches beating time on the Francigena, the Pilgrim’s Way.

I’ve come to Italy to walk with him for a couple of days and make a programme about him for the BBC.

In 2021 he walked from his home in Brittany to Santiago de Compostela. Now he’s embarked on a new pilgrimage, again to Santiago but this time starting from Rome. 3200 kilometres. On one good leg, one prosthetic leg and crutches.
