Welcome Legs in Pain. Good luck with the healing and training.
On gels: Despite not minding the taste of the SIS ones, I find gels make no difference to me whatsoever if I can get hold of bananas. Does anyone know what drink (gatorade?) they are likely to use in NY and if they will also provide fruit (like Berlin but not Boston did)?
On diet: More or less like Trin said. I basically eat all the carbs I can manage (a lot, believe me) from the Thursday, including (sorry Trin) a large meal late afternoon/early evening Saturday. I then usually have at least two bagels and two bananas on race day morning. At NY, it is possible I will eat even more than this on race day! (My body is very used to processing food and I don't suffer from stomach cramps.)
On the wall: In addition to diet, rest, etc., I think there is a strong effect of past running. Training for a second marathon builds on a base already established and the wall is further away. The more marathons you've done, the less one worries about the wall (assuming consistent training throughout). And, like NotCat, I think getting in as many long (18 mile-plus) runs you can, the less you will need to fear the wall (although I usually don't exceed about 50ish miles a week).
On travel: My NY running friend is giving very similar advice to Tortie. I am definitely leaning towards NJ-near-a-PATH station. Tortie, assuming we don't hate each other if we met up before the race, might us travelling to the start together be a possibility?
On coffee: I need one. Laters.
