Perhaps I didn't say enough. The descriptions and comments I've read here and many times before are of roads rammed with cyclists, many walking, making it difficult to make progress. There would be no joy in this for me.
If one's comfortable pace, steady riding, stopping for views, coffee etc. is 60 miles in six hours that's an entirely different matter.
The first scenario puts me off, the second is what cycling is about, moving at one's own pace as and when it suits not being forced to stop, start etc.
I see those very differently. Apologies if I've unintentionally inferred slow riding is in some way pointless.
