NOOB- all advice welcome

I committed to hiking all of NY in sections, 2-5 days at a time (might add on states as I grown in confidence). I’ve done many day hikes and hit the gym 2-3x a week but I’m in no way experienced.

Some questions that come to mind as I start to plan:

What are the distances between campsites/shelters?

How often might there be water sources?

Are there any recommended sections or should I just start at the jersey border?

Any additional advice or words of wisdom?
