Marathon bound

No, I'm not heading to the city of Marathon in Greece in search of my hero Pheidippides, rather I'm committing to run my first marathon.  I've run 5k's, 10k's, 10 miler's, half marathons, and even a 30k but the full marathon race is still on my list to conquer.
Since I started seriously running several years ago I have been intrigued by this small local marathon and this year I'm going to give it a shot. The timing is right with my family affairs and my training and I figure why not?
I know the course well since I run on it weekly if not more.  It's close to home and low key....all necessities for my first marathon.  Even though I am familiar with the course I know it's not going to be easy.  There are several hills on the course and in fact the elevation chart looks pretty scary.  But I have 5 months to train and feel pretty good about it at this time (easy to say now right?)

So does anyone have any marathon training tips they can share with me?
