Thanks to Nothing happening, I've got a multitude of aches and assorted interestingly-coloured bits. Everything except the Achilles, it seems, so I'm declaring that an overall win.
As I said at the time, Knees™ mean that walking downhill can be problematic
[1] for me, and even if I have to use the 24" gear to get up, a mountain bike lets me get back down again with much less walking. It's nice to get to places like that, away from the roads. I keep forgetting how fun technical off-road riding can be, though I admit my comfort zone for that involves more trying to stay upright in treacherous (but ultimately harmless) mud than bouncing downhill over scary-looking rocks at what's invariably the wrong speed.
There was a point where, about halfway up Coldwell Clough - and after a fair bit of faffing around with cows and navigation errors and descending the sort of rutted singletrack that could pass for a drainage ditch - proper mountain bikers in body armour started coming the other way. I was feeling my general lack of fitness and started to have doubts about the sensibility of continuing, but turning back is abhorrent and the easiest bailout option was to push on to the main road. Once we got to the top the going got much easier, the view became worth it, and - Wowbagger's mildly inappropriate bike
[2] notwithstanding - I reckoned (more or less correctly) there wouldn't be as much prolonged unrideable stuff. The pretty bit with the fords (and the rather enjoyable descent to get to them) made the whole thing worthwhile, IMHO.
[1] I had a moment walking on the moors above the Upper Derwent about 12 years ago where a fatigued knee failing to lock caused me to slip and twist an ankle. Getting back down was slow going and unpleasant.
[2] Actually Mrs Wow's Thorn, which coped admirably well, given the limitations inherent in cow-muddy off-roading on touring tyres. Just as well he didn't break it.
