The Senda is a long walk. Like its elder sister, the Pyrenean Way (GR10) in France, it runs from the Atlantic coast to the Mediterranean, taking in the entire length of the mountains. With over 950km to hike and around 42000m of climbing it is a serious trek. Kilian Jornet may well have brushed it off in eight days but ordinary humans will take at least six weeks.
Yet there’s more to the GR11 than the one and a half million footprints and the encounters with other nomads. It is also a window on a way of life. The last vestiges of the Old Mountains are still visible in recently abandoned hamlets and overgrown hedgerows. And the New Mountains are moving in, bringing with them infrastructures and ideas conceived on the plains.
