Cardiovascularly I was okay when I started, but none of the muscle groups and joints, etc were in shape. Nothing gets you in shape like just getting out there and hiking day in and day out. And give yourself time to build up to the regimen of long distance hiking, no matter what shape you're in. Don't push too much too soon or your knees and shins will dislike you real quick.
My best to this year's hiking class. Thinking of you.
