Garry_Lager, I do honestly think so. For example I was down there one evening last autumn with a pal that lives close to GT. He took me down a route from the top of Spooky that hardly used an inch of “official” trail. Some of it, Secrets and Lies for example, I’d been on before, but some of it I hadn’t. And there were other routes he was talking about that I know I haven’t been on. Some of them admittedly I probably never will be on as they are beyond my limited ability.
There’s a huge amount of forest there. I’ve done the GT Duathlon series a couple of times and the running bits have taken in bits of the forest I’ve never cycled.
You’re right about Inners though.
