I'm 38, decent shape, very avid hiker/runner.
Doing my first section hike this summer in TN.
With work/family commitments as they are now I'll average 100 miles per year. That may change in the future. It must!
Wife is supportive and will drop off/pick up in any state.
I get one week vacation on my own for hiking at will and one week for family (non hiking).
Don't want to be too old to finish the AT.
I have an "important" career and wish I could take off for a few months to do the AT.
*sigh*
