The Camino Fances is but 850 kilometers and should be perceived as only the last leg or better the trunk of tree with branches extending thousands and thousands of kilometers stretching throughout Europe and Scandinavia, runners all over the world. There is no real starting point but there is a root or a source in Santiago. Do part of it. If your decision is spiritual, begin at Saria, 100 kilometers at your own pace, walk triumphantly into Santiago and claim your Compostela. I find other stretches of the Camino less crowded and more predisposed to introspection, for spirituality. Art and architecture-Burgos to Leon. Nature-Saint Jean to SantoDomingo. Decide the why, do whichever section fits, fix goals set within your own reality and do it! The Camino will wait for a return visit(s), after you have learned the ropes and you have a better handle on personal issues.
