A better runner

Next Saturday I have my 100km race. I don’t think there is any running I can do anymore to improve myself. So I’m reduced to focusing on nutrition.
Carb-loading.
The key here is to eat a lot of carbohydrates before the race. They provide the energy you burn when running. So for three days I will eat as much of those as possible. However, you need to prime your body to be very accepting of carbs. And the way to do that is to not eat any for three days.
Carbs are in a lot of things.
Today was the first day. I’ve been eating eggs, meat and cheese. It has been hell. The biggest problem is that meat without any carbohydrates is somewhat hard to make. So I’m not sure if I’m always hungry because I haven’t been eating enough, or if my body is just craving carbs.
I have been dreaming about vegetables.
At eye level in my fridge is a cupcake leftover from yesterday’s party.
