How did you get on? I was going to suggest the Tak Ma Doon Road above Kilsyth, or The Crow Road above Lennoxtown.
Depends a bit on where you live, and how fast you drive. I know someone who’s done Edinburgh in around 20 minutes. Although that was with a police escort so doubt you’d be able to match that.
