Ultramarathons are a true test of endurance, both physical and mental. These races can last for hours or even days, and require a significant amount of energy to complete. That’s why having a solid nutrition strategy is key to success in these events. 

In this article, we’ll outline some important hints and tips for an effective ultra nutrition strategy. 

What is an Ultramarathon Nutrition Strategy?

The main objective of an ultramarathon nutrition strategy is to provide your body with the right fuel to sustain energy levels, maintain optimal physical function, and promote recovery. 

The strategy encompasses various aspects of nutrition, including meal planning, hydration, and supplement intake. The ultimate goal is to ensure that your body has the necessary nutrients to perform at its best and to avoid the negative effects of fatigue, dehydration, and injury.

Meal planning is a critical component of an ultramarathon nutrition strategy. Before the race, you should aim to consume a balanced diet that includes complex carbohydrates, lean proteins, and healthy fats

Complex carbohydrates provide a sustained source of energy, while proteins help to repair and rebuild muscle tissue. 

Healthy fats are essential for overall health and also provide a source of energy. Planning your meals in advance can help ensure that you consume the right balance of nutrients and avoid consuming foods that may negatively impact your performance.

Hydration is also a crucial part of an ultramarathon nutrition strategy. Dehydration can lead to fatigue, cramps, and heat exhaustion, which can negatively impact your performance. It’s essential to start hydrating before the race begins and to continue drinking fluids regularly throughout the event. 

You should aim to drink at least 16 ounces of fluid every hour during the race. Water is a great choice, but electrolyte drinks can help replace the minerals lost through sweat.

In addition to meal planning and hydration, an ultramarathon nutrition strategy may also include the use of supplements such as energy gels, electrolyte drinks, or protein powders. 

Energy gels are convenient and provide a quick source of carbohydrates, while electrolyte drinks can help replace lost minerals. 

Protein powders can be used before or after the race to help repair muscle tissue and aid in recovery.

Why is an Ultramarathon Nutrition Strategy Important?

Proper nutrition is critical for any athlete, but it becomes even more crucial for ultramarathon runners due to the extreme physical and mental demands of the event. 

Ultramarathons typically cover distances of 50 kilometres or more, with some races lasting for multiple days. Running such long distances requires significant amounts of energy, and your body needs the right fuel to sustain that energy.

Without proper fuelling, you risk hitting the wall or experiencing fatigue, dehydration, or injury. Hitting the wall is a common phenomenon that occurs when your body runs out of glycogen, which is the primary fuel source for your muscles. 

When this happens, you may feel exhausted, and your performance can suffer. Dehydration can lead to a host of negative effects, including cramps, heat exhaustion, and even organ failure in severe cases. 

Injuries can also occur due to the stress and strain placed on your body during an ultramarathon.

An ultramarathon nutrition strategy can help you avoid these issues and optimise your performance. By carefully planning your meals and hydration, you can ensure that your body has the nutrients it needs to perform at its best. 

Consuming the right balance of carbohydrates, proteins, and healthy fats can help keep your energy levels up and support muscle repair and recovery. 

Proper hydration can help prevent dehydration and maintain optimal physical function. 

Additionally, supplements such as energy gels or electrolyte drinks can provide a quick source of energy and replenish lost minerals.

Meal Planning

When planning your meals, it’s important to consider the timing of your meals and the specific needs of your body. Before an ultramarathon, you may want to increase your carbohydrate intake to boost your glycogen stores, which can provide energy during the race. 

During the race, you will need to consume calories to keep your energy levels up and prevent hitting the wall.

It’s essential to test different types of food and drinks during your training runs to see what works best for your body. Some runners prefer solid foods such as energy bars, sandwiches, or fruit, while others prefer liquids such as sports drinks or gels. Some runners may even use a combination of both.

Hydration

Hydration is another critical component of an ultramarathon nutrition strategy. Proper hydration can help prevent dehydration, which can lead to a host of negative effects such as cramps, heat exhaustion, and organ failure in severe cases.

The general rule of thumb is to drink enough fluids to maintain a pale, straw-coloured urine colour. While everyone’s hydration needs are different, most experts recommend drinking 16-20 ounces of fluid per hour during exercise. 

Sports drinks can provide a quick source of energy and replenish lost minerals, but it’s also essential to consume water to maintain proper hydration.

Supplements

Supplements such as energy gels or electrolyte drinks can provide a quick source of energy and replenish lost minerals during an ultramarathon. 

However, it’s essential to use these supplements in moderation and not rely on them as a sole source of nutrition. Too much of a good thing can have negative effects, and consuming too many supplements can lead to digestive issues and other problems.

Learning to Eat While Running

Learning to eat while running can be challenging but is essential for maintaining energy levels during an ultramarathon. 

Eating during a race can also help prevent fatigue, cramping, and other issues that can arise from prolonged physical exertion. Here are some tips on how to eat while running during an ultramarathon.

Practice, Practice, Practice

Practice makes perfect, and this is especially true when it comes to eating while running. Try different foods and experiment with different timings and quantities to figure out what works best for you. 

During your training runs, try to simulate race-day conditions, such as carrying the same gear and eating at the same intervals. This will help you get used to eating while running and avoid any surprises during the race.

Choose the Right Foods

The best foods to eat during an ultramarathon are those that are easily digestible, provide a quick source of energy, and won’t upset your stomach. Energy gels or chews are a popular choice as they are easy to carry and consume on the go. 

However, some runners prefer real food, such as bananas, peanut butter and jelly sandwiches, or boiled potatoes. 

Whatever you choose, be sure to pack it in an easily accessible location, such as a waistband or hydration pack.

Timing is Key

Timing is crucial when it comes to eating during an ultramarathon. Waiting too long to eat can lead to low energy levels and performance decline, while eating too frequently or too much can cause gastrointestinal issues such as nausea and cramping. 

A good rule of thumb is to eat small portions every 45 minutes to an hour. This can vary depending on your individual needs, so be sure to practise during training to find the right balance for you.

Perfecting Your Own Ultramarathon Nutrition Plan

An ultramarathon nutrition strategy is essential for anyone looking to complete an endurance event successfully. 

It’s important to plan your meals, stay hydrated, and practice eating while running to ensure that you have the energy and nutrients necessary to complete the race. 

By following these guidelines, you can optimise your performance and achieve your ultramarathon goals.

Remember to listen to your body during the race and adjust your nutrition strategy as needed. Everyone’s body is different, and what works for one person may not work for another. With proper planning and preparation, you can create a nutrition strategy that works for you and helps you achieve your ultramarathon goals.

If you need help creating an ultramarathon nutrition strategy, consult a registered dietitian or sports nutritionist. They can help you develop a plan that meets your individual needs and ensures that you have the energy and nutrients necessary to succeed.
