Still hooked on adventure after their long pilgrimage to Santiago de Compostela, a few years later Mefo Phillips and her spotted horse Leo set off again from Canterbury, this time heading for Rome, with Mefo's husband Peter once more trying to keep track of them in Bessie the Bedford horsebox. Turning her back on the main route of the Via Francigena through France and Switzerland, she opted instead for the road less travelled, a secondary pilgrim route that climbed directly over the French border pass at Mont Cenis into Italy. Their journey turned out to be far more challenging than the previous one, with no pilgrim infrastructure, incomprehensible maps, wild mountain weather followed by doldrum days in the baking Po valley, and even a heart-stopping fall down a ravine. But it was a journey of great highs as well as lows: the unexpected view of the Mont Blanc massif drenched in snow; crossing the Col de l'Iseran through ghostly clouds at 9000 feet; catching sight of the Mediterranean Sea for the first time as she and Leo came down from the Apennines above La Spezia; and the wonderful jumble of hospitable humanity they met as they followed tortuous paths across Europe. Although the backbone of Long Rider to Rome is the amazing experience of travelling with a much-loved horse, there was another reason for this pilgrimage: Mefo's writer and rider mother had died from Alzheimer's disease, and she rode in aid of the Alzheimer's Society and to make an equine journey she believed her mother would have loved to do herself. Memories of her are woven into the narrative, triggered by Mefo's own experiences as she rode along; she was determined to get to Rome, and 108 days after leaving Canterbury she and Peter walked with Leo along the banks of the Tiber, and cut across the city's teeming streets to arrive finally in St Peter's Square.
