I am walking through the mountains of norway, Bergen to Oslo starting tommorow.

I have a list of what I am bringing.
Make a suggestion if there is anything else I should take with me, would love input.

1. Tent.
2. Sleeping bag.
3. Portable cooking/frying pan that runs on propane.
4. Fishing rod + required.
5. 1 extra shirt, 1 extra pair of underwear, 1 extra shorts.
6. Rain pants and rain jacket.
7. USB charger, solar powered.
8. Water-tight plastic bags.
9. Insta-fire kindling.
10. Two knives, both sharpened.
11. Three books.
12. Two phones.
13. Notebook for writing.
14. Cast on.

Anything else I should bring?
This is more or less my first time on such a long trip, it will probably take me 3-4 weeks.

How does food work?
I am going to buy a loaf of bread for my first week and alot of dry-food that you only add water too.
Also thought about bringing along a little coffee can-thing and some coffee, but dunno if I should skip the coffee as I dont want to make a habbit out of needing coffee for walking.

I am in terrible physichal condition as I am pretty much starving myself half to death at the moment. And I never use my body, I wont quit but I am underestemating how challenging this will be I think.

If you have any input, I would appreciate it, I am starting tommorow at 12.
