there's a "long hike" tab on this site you might like to read..as for videos, I'd suggest watching just about anything by "Homemade Wonder lust" she is a very prolific writer/ video producer. I feel her Pacific Crest Trail hike would be the most relevant to your proposed hike.(just keep in mind, yours will NOT be as grueling) a few of her's deal with resupplying stops-something that has a lot of relevance to your hike. since I suspect your hike would have many more resupply opportunities available as well as over night hotel/hostel accommodations available.. which would allow you to lighten up that pack a bit, and make this more of a cultural exchange than her normal LD hike.
