Well, I realised I hadn't included any pre-walk photos yet. They're generally not very interesting: people's backs as they walk up the road, but for completeness, here's one on at Mutianyu. The pre-walks were an opportunity to warm up, get into a walking frame of mind, and (for me at least) work out exactly how many coats I should actually be wearing - usually a couple less than I had on. On this particular pre-walk I was feeling pretty green, nursing a bit of a hangover, which fortunately passed before I hit the wall.
