I would like to echo Lori's suggest to start with something a lot easier than a one-week solo hike. And yes, even though we have a TON of experience, we almost always test any piece of equipment in the backyard before we take it on the trail.

But one note in defence of the OP....he is hiking in Minnesota. No altitude sickness to worry about!
