I am planning on eating a bowl full of oats, bran, yoghurt and stewed fruit for breakfast at around 7am, .........
I would very much appreciate some guidance as to what and when to eat/drink during this event.
Solace, I'm guessing that it is your usual, healthy breakfast. You appear to be consuming a fairly large quanity of fibre there, which may not be your best friend during the race.
During the race, I find much of it comes down to personal taste. When it comes to fueling your body, no matter how osmotically balanced, high/low GI, scientifically tested a product may be, if you're going to look at it and think "If I eat that I'm going to puke.", it is going to be of no benefit to you.
A couple of rules of thumb I use for longer events include:
The longer an event and slower I'm moving, the more opportunities I will have to take in solid food.
"Proper" food tastes much better than specially designed sports foods. That's why Food Tech companies employ food scientists to manufacture their products with fruit or chocolate flavours. That is also why these same scientists are not employed to genetically modify a fruit so it tastes like a sports bar or a sports drink.
If I am thirsty and I can comfortably drink something containing some calories as well as at the same time hydrating myself, I might as well. Sports drinks (or cordial, fruit juice, coke) can be a very convenient way to keep them calories coming in.
The Great Potato Deity is divine in all its incarnations. It is advisable to pay respectful homage and worship the gods of Baked, Boiled, Mashed, Chips and Crisps at various times in your path to endurance enlightenment.
Olives taste better than salt tablets.
Trawl through some of the recent nutrition threads. There has been plenty of advice from runners answering similar questions.
Hope this helps in some way.
