Planning Backpacking Trips is both an art and a science, but I know more about the science. When I plan a backpacking trip, I always start out by making a chart. I include as many campsites, road crossings, and other useful way-points as possible. I then list the cumulative mileage and elevation gain from the beginning to each way-point. Then I calculate cumulative hiking hours to each of these way-points. I use this chart to decide the ideal starting and ending point for each day of the trip.
