20th works for me. Would have preferred the weekend after but will go with it!
Here's a route that avoids most A roads where possible (though still sticks to decently surfaced roads). There are a fair few quiet country roads whilst in the Peaks.

The very end involves a long gentle downhill along the A6 to get back to Stockport. I find coming back this way to be quite reasonable as you're moving at a similar speed to the traffic.
