What do you think is the ideal time scale for an end to end?
My view is around 2 to 3 weeks. I did it in two weeks and while the riding wasn't that hard (about 75mpd) I found that spending so long in the saddle (so I ain't that fast, OK) meant that I didn't actually have time to stop and stare at everything that took my fancy, and by the time I got to the days destination and found lodgings, it was gone 5pm and everything I wanted to mooch around was shut.
Fair enough, the end to end is a challenge, but I see that challange as being 1. actually making it to the other end, and 2) getting the maximum enjoyment out of it as possible.
Now, I'm no 'dissing' those that seek to do it in as little time as possible - I am in awe of their athletic abilities, but when you do it flat out at those sorts of speeds, then for me, it ceases to be a tour and becomes an unofficial race.
Of course, you could take more than 2 to 3 weeks and meander a bit to see a lot more, but then comes the world of pain from (s)he who you have left at home for so long
