I wouldn’t recommend hamsterley unless you are planning to do the DH runs
Now these do include big steep drops – not really what the OP is looking for from what I read… Great DH setup though, big bike highly recommended.
The majority of the red/black route is fire road or very tame singletrack.
But the OP has sensibly found one of the routes that crops out a lot of the fireroad, except for where it’s used in a sensible fashion, to gain height.
Oh I forgot to add, there has been a small addition to the bottom section of transmission, so it doesn’t spit you out onto the back of the grove car park any more, it’s a good section, but it might confuse you if you need to follow that map exactly.
