>>640762That's a nice pack for 2 or 3 days. Not months. You will perhaps last a week but not more, if I were you I'd gather much more experience because as I see you know nothing about hiking for at least multiple days, you lack the basic knowledge and you will only make yourself ridiculous.
Take your time, do a few longer walks where you spend a few nights outside, develop your basic outdoor habits based upon your freshly gathered experiences. Not only your body needs to be prepared, but a long tour like that will be mentally easier if the whole concept of living outdoors is not entirely new to you. Being able to handle the essential situations you shall encounter will give you a moral boost.
