Verderers is brilliant. last red section is long, fast,smooth, bermy and jumpy. (although it had developed some inevitable braking bumps and had broken up in places the last time I went )
There are some good sections in between as well.
Also do a quick loop of the freeminer’s trail to warm up.
As said, there is loads of stuff in the Forest to find. Dont forget the downhills to if you like it a bit more bumpy
