That was my initial question when I researched (rather than read) TSP via online marketing copy and interviews. I remember reading they were homeless on the SWCP for two years, i.e. implied they walked the whole lot in one go and had no option but to sleep rough.
I questioned that. It’d be incredibly tough through the winter. It’s hard enough to survive in a tent sheltered in woodland etc. through the winter. Even if young and in good health (or as good as your health can be while camping out in winter). Even with a home to return to. But on the coast? Plus, most areas have winter night shelters. You can’t always get a bed, and they can be hellish places, full of lots of desperate, traumatised and unwell people. But they can be an access point to hostels, advice etc.
So I dug a bit deeper and pretty sure I read they overwintered on a friend’s farm or somewhere. So, basically we’re only walking the path and wild camping from spring to autumn. While physically the same (i.e. out in the elements) there’s a very big psychological difference between choosing to walk and wild camp on a coastal path, as a form of pilgrimage or challenge, and being a rough sleeper.
I have no idea which the Walkers were. But the opportunity to stay with a friend over winter suggests the former. Sounds like they wild camped while knowing (even if they chose not to avail themselves of them at the time) other options were available. Such as staying with adult kids or wider family/friends until they could get a job or sell the land in France. Or asking DWP if they could claim housing benefit until it was sold - then repay.
This is very different to rough sleeping with no or few options: no one to stay with even temporarily; no entitlement to temporary accommodation; no one to help out with a tenancy deposit or act as guarantor, not even a council scheme; not enough housing benefit to afford the rent (even on the crappiest room in the worst house); no landlord willing to let to you; few opportunities for healthy food or a hot shower; no one to turn to for moral support, apart from others in the same position.
With the latter, what pervades is a feeling of despair that this is it: there are few options to ever get out of your situation, however positive and resourceful you are or however hard you try. Every step you hit a barrier. It’s degrading. Health (physical, mental and psychological) deteriorates v quickly for obvs reasons. You have to be very tough to survive.
