A very frequent question when planning an E2E is the route in the far south-west. The main A30 through Cornwall & Devon (or Devon & Cornwall for JOGLE) is notorious - much of it is motorway in all but name yet cyclists may ride on it.
The content here has suggestions for a route from Land's End as far as Tiverton Parkway, with a supplementary route avoiding the A30.

Click the link - the .gpx files will open a download window and the .pdf files will open the map in a new window (the file can then be saved)
The .gpx files can, of course, be reversed to load into GPS gadgets
