A good friend did LeJog this year in 12 days.
His takeaways that he shared with me were:
- the first part through Cornwall and Devon was MUCH tougher than he had expected
- he was at about 3.5 w/lg FTP and managed it ok - but felt well and truly shelled by the last two days to go
- he built up his mileage and time in the saddle gently but progressively over the months building up to the event but acknowledged if doing it again he would have aimed to hit a higher volume (at an easier intensity) earlier to build up and strengthen his tolerance
- if doing again he would have allowed a couple of extra days before the event to absorb his training / rest / carb load etc so he felt stronger and fresher at the start
- he ate LOADS along the way and at the end of each day but felt even then he probably could have done more to optimise his nutrition to offset the impact of consecutive tough days
- he would recommend seeking to work into his prep (if doing it again) a few blocks of four or five consecutive hard days just to get a good sense of how his body responded to the efforts and stress
Hope this helps
