What To Eat Before A Half Marathon

A successful half-marathon run requires a lot of hard work and dedication. Long hours of physical exercise and cardio intertwined with a strict dedication to a healthy diet is what trains our body and mind to persevere and succeed in this kind of spectacular road running event.

Daily early morning jogs, warm-ups, weight lifting, and cardio exercises are crucial for the preparation of a half-marathon. After all, running approximately 22 km straight is no joke. We cannot expect to attempt it without mere preparations.

Although work-outs and jogs are the highlights of this preparation, the other key factor that contributes to its success is food.

The Half-Marathon Diet

Food plays a very important role in getting ready for a marathon, and burgers and fries are out of the equation. A strict and healthy diet with a proper balance of the correct types of calories is a necessity.

Perfect jugglery of carbohydrates, proteins, and minerals is the basic framework for this event and the leading calorie is carbohydrate.

Carbohydrates are the core source of fuel that a runner needs. We need to turn up our carb intake and combine it with various sources of proteins to form the perfect diet.

Hydration is a necessity. A shortage of fluids in the system will dehydrate the body and drain it off all its energies.

According to some accurate calculations, the body requires a calorie intake of over 500 grams for any race over 2 and a half minutes.

Research data suggests that a 1:30 min race time requires 100 calories. The calorie requirement becomes 300 for 2:30 mins and over 500 for any race above 2:30 mins.

However, these evaluations are strictly variable for different runners and we should take it as a suggestion rather than a cold hard fact.

The best way to find out our calorie requirement is not by experimenting on the actual race day but to use the method of trial and error. This should be done months before the half-marathon.

These calories can be consumed with a share of 80% carbohydrate and 20% protein and various foods can contribute to this calorie budget.

High-fiber foods are required to be reduced day by day, as the main event approaches. We should not consume any fiber in the last few days of the race. It exposes the body to the risk of bloating, cramping, and diarrhea. Fruits, nuts, and legumes should be avoided because they are a rich source of fiber.

Dairy products like milk, cheese, butter, etc. should be avoided at all costs. They severely impact the body’s digestion and energy production mechanism.

Alcohol, marijuana, oily and fatty foods are a big no-no. After all, junk food eating and marathon running do not go hand in hand.

Countdown To The Race

The half-marathon is right around the corner and our diet plan should gradually change as the race approaches. Several tweaks are necessary and it all depends on the amount of time left.

Starting from a week to the actual race day, let’s dig into how and what we should be eating to maximize our output on the running track.

One Week

A week before the event is a very crucial time. The calorie intake should be 500 calories or above depending on a runner-to-runner basis.

An 80/20 share of carbs and protein should be followed. The carb intake is boosted a week before the race, to produce the fuel that will be useful for us in the marathon.

There are many examples of carb-rich foods such as the following:

• Brown Rice

• Wheat Bread

• Oats

• Sweet Potatoes

• Beets

• Lentils

• Kidney Beans

There are great breakfast choices like wheat bread or oats, and lunch options like brown rice, lentils, kidney beans.

Proteins would be the main side-kick to carbs in our dietary plan. The proteins consumed should be well balanced with carbs on an 80/20 sharing ratio and protein-rich foods should be healthy and not rich. Healthy sources of proteins are the following:

• Egg Whites

• Red Meat

• White Meat

• Soybeans

• Fish

Egg whites are perfect partners of carbs, like bread or oats, for breakfast. For lunch, we can go for fish, white meat, or soybeans combined with brown rice and lentils.

Red meat is a great source of protein but it is not recommended. White meat is far more preferable.

Healthy oils can be used in cooking these foods but the amount should be kept at a bare minimum. Few fibrous foods like fruits can be eaten on the first few days of the final week but the quantity needs to be reduced down day after day.

Three Days

The basic framework of the dietary plan remains the same. High carb foods partnered with lean proteins with a dash of healthy oil should be followed.

Fiber-rich foods such as different types of fruits need to be cut out. Although it is good for digestion, as the event closes in, the risk of bloating and cramping on the main day becomes significant.

The Night Before

It’s almost time. The half-marathon is just the next morning and dinner on the previous night has high significance.

The calorie formula remains the same. High fiber foods are cut out. It is generally preferred to have a sufficient dinner but never overstuff the body. Too much food, especially carbs, can cause sluggishness the next morning.

Staying hydrated is a key point but we should not overdo the fluids. Overhydration can cause cramping and ruin the sleep cycle.

Any kind of alcoholic beverage should be completely banned the night before. That will just ruin all the days of hard work and make you sleep-deprived.

Speaking of sleep, that's the most important thing to consider. Sleep is more important than the food itself. A good night's sleep will refresh the body the next morning and then we can get the maximum output out of ourselves.

So, an early dinner and early bed are highly beneficial.

Early Morning Breakfast - Race Day

The day we have been preparing for such a long time has finally arrived. The marathon is here and it's about time to get geared up and move ahead to the running track.

But first - breakfast. We will need to fill up our gas tank with the last bit of fuel that our breakfast will provide us.

It is advisable to consume 300 calories of food, 2 hours before the half-marathon kicks off. Consuming 500 calories is okay if it can be completed 4 hours before the race.

Half-marathon usually begins early in the morning and to have breakfast 4 hours before might lead to sleep deprivation so it is better to stick with 300 calories, where we have 2 hours till the whistle blows.

The standard framework will be maintained with a high amount of carbs coupled with a portion of protein. Oils, fibers, and other types of food should be strictly avoided.

So, race day breakfast can cover 300 calories with combinations like bread and egg whites. Oats can also be a good substitute for bread. Brown rice should be avoided because it can overload the system. Chapati is also a proper source of carb which gives a boost of energy.

Finally, the body should be properly hydrated. Drinking adequate amounts of water is necessary but we should not stuff our stomachs.

Proper energy and health drinks are recommended before and during the marathon. Gatorade and Glucone-D are great options. Avoid energy drinks like Red Bull and Monster. They are not made to energize our bodies for any athletic activity. They have rather recreational purposes.

A well-balanced and scientifically accurate diet with proper hydration and a great sense of sportsmanship is the key to a successful half-marathon run. So, pack your gears and begin your journey to prepare for a spectacular event.
