I would focus on my 400 meter splits and where my competition is. You should have a pretty good idea what you can run so the goal is to run even splits every 400 meters. A 10 min 2 miler should run 400 meter splits in approx. 75 seconds per lap.
You also need to see what your competitors are doing- you can draft on windy stretches. During the last 800, you have to decide when to make a move- depending on where your competitors are- if you are fast you can afford to sit and wait until the last straight. If you are slow you need to think about a long sustained kick.
