Nutrition is just as important as the actual training, maybe even more so. I haven't been able to get a decent diet plan going since moving to Germany, but I'm determined to this time for the sake of the marathon.
A lot of runners go for the "carb loading" approach, where over 60% of their calorie intake are complex carbohydrates, such as whole wheat pasta, bread, pulses and lots of fruit and vegetables. In most ways I will emulate this approach, as in general it is a healthy approach. The reason for this is that it increases the store of glycogen in the muscles, which is premium grade fuel for endurance training, and proven to make the difference on my long runs.
A general rule of thumb is that runners burn 100 calories per mile, but for me right now it is up over 150 calories per mile! That will reduce over the course of the training as I lose some weight and increase my efficiency.
I have set up a folder in Google Docs for some example recipes here. If you have any ideas drop them in the comments (preferably with URLs :) )
Viel Spaß homies!
