For those that would like to organise their own routes, these two websites may help:
Green Lanes in Cumbria -->

Green Lanes in Northumberland -->

Most Lakeland lanes will be OK on dual sport tyres, if it has been wet then you'll need to take extra care. The lanes around Alston are generally more peat/muddy so TCK-type rubber is better, but it
can be hard going at times.
