Yeah, you’ll be up against it chap.
I’ve spent a whole load of time in Flo’ and of all my (roadie) mates, all bar one were roadies only. The MTB’er took his bike to the Alp’s…
It’s a difficult one this cos’ all the “tracks” tend to be fire/chalk/limestone tracks to/from fields or small (very) villages. You’ll be riding around on quite well surfaced tracks as most are flattened by tractors/cars. Forests, erm.. large woods you mean, well there are tracks through them but again it’s bramble and ferns with very few “paths” to play on.
I’m not one to dampen spirits, but in 3 years there I’ve only ever roadied.
