A mini load may only require you to load for one day as well as taking extra fluids whilst tapering. You are what you eat - there are no magic foods. Choose foods that you are familiar with and feel comfortable eating. Eat at least 2-3 hours before the event. This meal should be high in carbohydrates and low in fat and protein.
Australian rice is great.
Eat enough to satisfy hunger. Keep the fibre content in the meal low. You don't need to be finding a toilet in the middle of transition. Also, dnnk plenty of water. On the morning of a race, walk around wlth a drink bottle, this will help to hydrate yourself.
