Plot: Michael's Pyrenean quest continues with the physical challenge of the French High Pyrenees, which he enters at the Cirque du Gavarnie, a 1,700-metre-high wall of limestone forming a natural amphitheatre. He struggles on across the snowy Plateau de Saugué to meet Marion Clignet, a French Olympic cycling champion who refused to let her epilepsy curtail her career, as well as finding time to reflect on his time as defence secretary, and on the current war in Europe
