Hi, I'm new here. I was hoping for a bit of advice.

I've day-hiked on many easy/moderate trails, and gone tent camping often (only at campsites with facilities). I've never gone "primitive" camping or backpacking before. I'm also out-of-shape (not obese, just weak right now from sedentary living). Strenuous uphill hikes make me winded easily.

I don't want to work out beforehand. I'm kind of an all-or-nothing spontaneous sort of fellow

Some literature warns people like me from trying a thru-hike. My view is that if I take it slow and take longer than usual breaks, I'll adjust along the way, even if I have to rest off some charlie horse for days at a time in the beginning.

Am I nuts to think this is doable? Will I just injure myself, or be completely miserable, and should not even try this?

Thanks for any advice -- especially from out-of-shape people who've tried this before, if there are any; it would be cool to hear those stories. PS. If this post violated some etiquette or is in the wrong section I apologize, it's my first one here.
