Why do people complain that "everything is rideable"? What do these people want, stuff that *isn't* rideable? What would be the point of that? It's akin to going on a track day and complaining that you could drive the whole track
Actually that's exactly right. Trail centres can be like track days. You turn up, follow the arrows and go as fast as you can. Sometimes that's great, but sometimes I want something more like the Dakar rally. I want to have to stop and metaphorically dig the car out. I want tracks that peter out to nothing and I have to carry the bike over a peat bog, I want river crossings that I may or may not be able to get through without getting wet through I want to explore that little gap in the trees which may be nothing or may lead to the best bit of singletrack ever.
In short I want an "Epic" and when was the last time anyone had an epic (in the true sense) riding round Whinlatter? I've ridden most of the trail centres in Britain, and the days spent doing them don't even rank in my top 50 days out on a bike. Most of my top 50 involve getting lost, getting wet, watching the sun set from the top of a mountain (big hill), then realising my lights are still in the car, dragging a rucksack full of stuff to a remote place to spend the night, then watching the sun rise over a mountain tarn, finishing my last energy bar with 40km left to go and my legs feeling like they're on fire
Note I am not saying that trail centres are rubbish, just that they are not the be all and end all.
