I'm pretty much with the others. Pre-HM I taper for a couple of weeks. I do try to make sure I'm well hydrated the day before the HM, and I do take on the road nutrition, Gu or Gel, or Shot Blox, that I use at about mile 8. I try to make dinner the night before "not too heavy" but carb-laden.
You might need more on the road nutrition, since you are a faster runner than I, probably using more calories.
You'll find what works for you... some of what I do, I found out "accidentally".
Defeat is temporary: giving up makes it permanent! Never give up!
