Hopefully you have asked yourself what to eat before a marathon as your pre-race meal before the day before the marathon actually arrives!
Let’s talk about though what makes a great pre race meal for runners running a marathon the following day.
What should the meal consist of and ideally when you want to eat it.
Exercise Physiologist, William McArdle says that the pre-competition meal should provide adequate carbohydrate energy and ensure optimal hydration.
It should “maximize muscle and liver glycogen storage and provide glucose for intestinal absorption during exercise”.
You should therefore never even consider doing a period of fasting before a race as it would be physiologically detrimental to your performance.
Most marathons are scheduled for the morning and some can start extremely early depending on the race.
Therefore your dinner the night before will become your pre-race meal.
However if you have an afternoon or night marathon then you will schedule your pre-race meal to be at breakfast or even lunch.
Here are some pre-race breakfast ideas that you can prepare before race day.
No matter when your marathon is scheduled to begin you want to end your pre-race meal at least 3-4 hours before the marathon begins.
This timeframe is because it will take about 3-4 hours to completely digest and store the energy into your muscles and liver from your meal to be available as energy during your marathon.
In fact, your pre-race meal should be the end to your carbo-loading plan that you have probably been following leading up to your marathon.
Here is why + how you can carbo-load before a marathon.
Here’s why you need to focus on carbohydrates:
Consume about 3-5 grams of carbohydrates per kilogram of body weight. This is a range depending on how much you already weigh.
If you do not know what your body weight in kilograms is then here is the simple conversion from pounds to kilograms.
_____________lbs (your body weight in pounds) / 2.2 lbs/kg (the conversion factor to change pounds into kilograms) = ________________ (your body weight in kilograms)
Nutritional energy bars can provide a quick blast of necessary nutrients before your marathon however they usually are higher in protein and fatty acids.
They also usually have not been assessed by the FDA and so the claims and macro nutrient labels have not be validated.
The bottom line is that they may be effective for you but should be combined with other foods.
If you simply cannot eat before a marathon or prior to 4 hours before your marathon start time then you will want to obtain your nutrients through a liquid drink, specifically through your energy drink.

Remember that you want your focus to be on foods that contain large quantities of carbohydrates so that you can adequately store energy in your liver and leg muscles so that ultimately you avoid the wall. (You will still need to refuel throughout the race but this is will get you started on the right path!)
