[pct-l] Creating a hike plan?

[kristen.haynes at comcast.net]

My friend and I are planning to do our first thru hike and we're interested in finding out how you all planned ahead-  knowing what pace and how many miles a day you'll be doing in which sections? When the terrain changes and youll be climbing for most of a week or whatever the situation is- you just find that our by reading in the guidebooks ahead at home? Or find an average speed and go from there...
We have created something like this on excel your feedback and examples would be appreciated!
