I notice in your report you said you did a lot of planning. Is it hard to find resupply points on this route or was it because you were worried about missing the time cut?
Planning reason:
1. I enjoy it.
2. Shawn said it was a good idea.
3. Resupply is difficult especially on a Sunday.
4. I felt it was right at the limit of what I could do. Knowing what was coming up and how to pace and not panic worked for me.
I know you are pretty quick and go pretty far so just to focus first on resupply, zilch for stages 1,2 and most of 3. Then night stages are obviously sparse. Towns are mostly avoided. Village shops have short hours. But there is stuff there. I found it before leaving.
I scanned bivvy spots on streetview.
I use gps and probably could have got hold of Jonah's track but I don't like entering a purple line tunnel with no idea what country I'm going through. I'm finding out about my own adopted part of the world hence drawing my own track, maps etc. Plus following others tracks is a risk.
It was a real help getting hold of tracks later and checking I was in the ball park. I also wanted to be as faithful to the original as possible but had to replace 8 intermediate controls that were homes or village halls.
The other bit of planning was a failed effort at looking at accomodation (village b&b and country hotels not flexible enough) so moved on to bivvy research like you've been doing..
Some of this could be changed by a change of start time but it shifts the problems.. anyway I guess reason no 1 made it enjoyable. I'm only learning this still so I've not reached the quietly confident stage yet.
Go for it.
