I found what I think is a good article on Race-Day Strategies for Marathoners by Pete Pfitzinger.
Pfitzinger is the author of Advanced Marathoning. Even if you don't consider yourself to be an advanced marathoner yet, it's a good book if you've already run a few marathons. The section I've found most useful thus far is for those of us crazy enough to run multiple marathons as close as 4 weeks apart. I'm considering trying one of the schedules in the book for a fall marathon which means I will be upping the mileage again.
