Carb loading is the term used to describe a popular practice among marathoners that involves eating a meals high in carbohydrates, days before a big race.
The science behind it is that carbohydrates are the main macro-nutrient that fuels our energy during a long distance run.
If by “loading up” on carbs before a race, the body should have maximum stores of carbohydrates to be turned into glycogen which will be stored in the muscles and used during our runs to keep supplying us with energy and ultimately give us the ability to run far and fast.
That was a mouthful.
But essentially this is the reason behind all of those spaghetti dinners that races hold generally the night before the race.
There are people who argue about whether carb loading really helps or not.

Some runners prefer to only do 1 day of carb-loading the day before their race and then focus heavily on there race refuel plan during the marathon itself so as to avoid hitting the wall.
If you would prefer to do this then aim for at least 10 grams of carbohydrates for every kilogram of body weight that day before your marathon.
