Yes, he is planning to get a reasonable sleep each night, he says 6-8 hours in the interview above. There’s also a description of his setup and I think some pics (certainly seen some on instagram EDIT: as above!). He’s basically using his normal race bike with some aero bars, custom frame bag, saddle bag.
The comparison with the other events is fair enough but he’d not generate the same kind of buzz doing those (given he has already done a fair few other events!). This route is also really hilly, he was saying about 65,000m
