You’ve missed the whole of the military lands to the NW of Guildford. Broadly the area centres on Deepcut and is bounded by the A324 to the south east, the A322 up the east side, the A331 on the west side and the M3 to the north. And that’s just the start.
From my house I can be off road in 1/2 a mile, and from there ride across to pirbright, onto the military areas, and do 5+ miles of almost entirely singletrack then on each of Tunnel Hill, Porridgepot Hill, Frith Hill, cross into Swinley and Crowthorne Woods, head over the ridges to Yateley, Eversley, Warren Heath, Minley – all with miles of ST there as well, eventually down past Fleet Ponds and onto Caesers W of Aldershot; then Basingstoke canal back to Tunnel hill and back via Pirbright to home. Not difficult to link together 600-odd miles of riding of mainly singletrack and very little road if you know where to look.
Get the OS out and find the areas above and have an explore. Or hook up with eg: the Tunnel Hill Trolls. I’ll stop short of maps because these are army lands in the main, and while we are tolerated there I won’t advertise too widely either.
Other comment was meant tongue in cheek btw. But come and have a look, you’ll be pleasantly surprised.
