Well I attempted the section from Alton to Farnham this morning, and have to say it's pretty badly signed. Lost the trail in Lower Froyle and only found it again at the end. A passing cyclist put me back on track at Well, so I was fairly far off
.
The little I did see alternates between narrow country road and field side tracks. The country side is pretty, but not super inspiring.
If you're going to give it a go, I'd strongly suggest having a map to hand
