How many miles a day do you tend to cover on the Wales trip? Also, how many days of driving are we aiming to cover?
The lakes are gonna be congested with slow driving tourists after 9am til about 8-9pm every day in June/July. I propose we do a dawn circuit of the best mountain passes in the lakes, then maybe some gentle sight-seeing to round off the Lakes.
Next up would be Pennines, shooting out to Brough from the Lakes on the A66 then up through Middleton in Teesdale and on to Alston (Epic road with a couple very nice waterfalls en-route). From there, we could go down and back up Hartside Pass just because it's there. I'd then continue along the top of the pennines to the borders.
A cruise through Kielder up to Selkirk. Then Selkirk to Moffat (Another epic road). From Moffat it would be worth cutting across the A74(M) to join up a couple of roads in Galloway Forest Park. These roads in the borders have been a regular setting for Evo Car of the Year.
With a bit of care and attention, I reckon that could be arranged into a mighty fun route! All the roads mentioned have been tried and tested with the old man in his S2K
EDIT: Also, it would be nice if those attending stopped by mine one evening for a BBQ, beers and a chuckle at my pile of parts
