Q: I am running my first marathon in two weeks and was wondering whether there is anything that I should eat prior to the race to help my performance.
A: I assume that you have been training and eating a balanced diet for several months, a diet consistent with your own personal metabolic needs for the amount of energy that you have been expending during training sessions. Unfortunately, this, and not the one meal that you eat prior to the race, will be your vital asset to achieving optimal performance.
