It was for JGTS..
Basically, it's all about what you eat and drink.
If you eat "fast" carbohydrates, your blood sugar levels will drop too low in the end of the race.
A "fast" carbohydrate is any kind of candy, soda, redbull, pasta and rice with short cooking time. I.e 3-5 minutes (pasta).
The longer it takes to boil your pasta, the less processed the base food is..
The less processed the food is (close to the natural and pure format of the food), the slower your body will distribute it to your body.
The slower carbohydrates will not rush out in your blood, it will provide you with a more even flow of energy.
So you can say that a meal containing "fast" carbohydrates and a meal containing "slow" carbohydrates will give you the same amount of energy.
But the slower carbonhydrates will supply your body in an even pace over a longer period of time, and the fast ones will "throw" the energy out in your body, giving you a "kick" of energy, that lasts for a maximum of ~30 minutes.. Then your energylevel will fall drasticly, and by the 1 hour mark, you have less energy in your body compared to what you had before you even took the meal.
It's a bit more complex than that, but it's enough information to highlight the importance of what you eat and drink.
When it comes to fluids, there's nothing that beat water.
Thirst is not a good indicator of your level of fluids inside your body. When you feel thirsty, your level is already too low.
Keeping in mind that your body can only reload the fluid stock with 1dl / hour, you'll not be able to get your level up during the race.
It's important to drink often, but in smaller doses to ensure you keep your levels at a decent level.
Beeing thirsty 30 minutes in to the race and as a result drink 1l of water in a minute will only make you to visit the bathroom, and still not getting your fluid levels up to par.
So basically:
Drink:
Make sure to start drinking water in small doses from 24 hours prior to race.
Do not drink soda or redbull or lemonade during the last 12 hours at least (if you feel that you need to drink something else than water).
Eat:
Look at your plate.. "Divide" it in 3 equaly sized fields.
1/3 wedgetebles
1/3 carbonhydrates (the slow kind. Something like 13-15 minute pasta).
1/3 Protein (Skip ham and red meat. Salmon, Chicken, Tuna and egg are good sources of protein).
Make sure to eat according to this model at least 36 hours prior to race.
Things you should NOT eat or drink from 36 hours prior race:
Candy in any form.
Chips/Snacks
Soda
Energydrinks (redbull, monster, powerade etc)
Anything that containes "fast" carbohydrates or high levels of sugar.
(Sugar is the same as carbonhydrates).
If you want to eat during the race, drink water, and eat something really basic like: Hard rye bread. Perhaps with some cheese on if you want it a bit more tasty.
I hope this makes sence.
This is a pretty complex subject, and I hope you guys understand what I tryed to say. 👍
Following these advices, I'm sure you'll notice that you won't feel like you lack concentration and stamina in the end of the race.
A 3 hour race will ofc in any curcuimstance be a tough task, but eating and drinking can help you to perform thru the entire race. 👍
Oh, just one more thing..
You can drink redbull or eat a candy bar when there's 15 minutes left of the race to boost your energy in the end of the race. Cause afterall, if your energy level sinks after the race, it won't be a problem (from a competative point of view).
However, energydrinks and candy are never good for your health. 👍
But if you win at LaSarthe, who cares about health..
