I enjoyed reading your comments. I'm not sure that I read what you wrote or tried to tell ☺ but it made me think about whether or when walking is a valued pleasure or leisure activity, an absolute necessity or an activity that is regarded as of no great value and a bit "beneath oneself".
The following comment may sound callous but that is not my intention. Camino walkers sometimes draw parallels between the distance they walk and the distance that refugees and economic migrants cover who we see on our TV screens. You mentioned in particular "migrants from war-ravaged Middle East crossing the Balkans on foot". We read and hear about the so-called caravans in America. It made me curious just on the practical level so to speak. It is my understanding, certainly as far as 2015 in Europe is concerned and also one of the more recent events in America, that many cover large distances not on foot but in motorised transport of various kinds while in particular the border crossings are on foot. I've never spoken to someone who has fled from war or from very dire living conditions over large distances in recent times but I knew a number of people (most of them are no longer alive now) who did so quite a while ago in Europe, fleeing from various countries to various other countries. They tried to get to the nearest place that was safe for them, often a neighbouring country, and this is also true for the majority of war refugees in the Middle East today but often overlooked. I hope these comments are ok, I'm trying to avoid anything that may regarded as political or personal.
I myself have now covered a continuous distance of some 2000 km though not in one go. Voluntarily. This is something that intrigues me: how far you can actually get on foot in just 3 months. I wasn't thinking refugees. I was thinking Hannibal, Roman legionnaires, and a period in European history called Völkerwanderung / invasions barbares / período de las grandes migraciones / migration period that brought the Visigoths to Spain for example.
How's that for starters?
