The road from Devils Bridge to Sedbergh is twisty has reasonable visibilty and plenty of diverse corners. The section after Sedbergh is much more open and flowing better road surface and less likelyhood of sped traps. Devils Bridge area can be a chore on summer Sundays. I prefer early Saturday mornings - still plenty of bikes about but not too much in the way of tourist traffic. From Brough there is an excellent route to Alston via Middleton in Teesdale. From Alston you can travel to Haydon Bridge or Penrith on the A686 whichever way you choose the roads are excellent.
