Eating for performance, energy, and endurance

As an experienced endurance runner, I know firsthand the importance of proper nutrition and fueling strategies when it comes to running long distances. To perform at your best and sustain your energy levels throughout your run, you need to fuel your body with the right types of foods and in the right amounts. In this article, I will share my knowledge and experience with you to help you optimize your nutrition and fueling strategies for endurance running.


Macronutrients, such as carbohydrates, protein, and fat, are the building blocks of our diets and play a crucial role in providing energy and nutrients to our bodies. Endurance runners need to consume a balanced diet that includes all three macronutrients to ensure they have enough energy to fuel their runs, as well as to support their overall health and well-being.
CARBOHYDRATES are the primary fuel source for endurance runners, as they are easily converted into glucose, which our muscles use for energy. Endurance runners need to consume enough carbohydrates before, during, and after their runs to ensure they have enough energy to sustain their efforts. Good sources of carbohydrates include whole grains, fruits, vegetables, and legumes.

PROTEIN is also essential for endurance runners, as it helps to repair and rebuild muscle tissue that is damaged during exercise. Endurance runners should consume a moderate amount of protein, ideally around 1.2-1.6 grams per kilogram of body weight per day. Good sources of protein include lean meats, poultry, fish, eggs, dairy products, and plant-based sources such as beans, nuts, and seeds.

FAT is an important source of energy for endurance runners, especially for long runs. However, it is important to choose healthy fats, such as those found in nuts, seeds, avocados, and fatty fish, as opposed to saturated and trans fats found in processed and fried foods.


What you eat before your run can greatly impact your performance and energy levels. It is important to eat a balanced meal that is rich in carbohydrates and low in fat and fibre. The meal should be consumed 2-3 hours before the run to allow time for digestion. Good pre-run meal options include oatmeal with fruit, a bagel with peanut butter and banana, or a smoothie made with fruit and yogurt.
If you do not have enough time to eat a full meal before your run, you can opt for a small snack that is rich in carbohydrates, such as a banana, a piece of toast with honey, or a granola bar.


For runs lasting longer than 60-90 minutes, it is important to consume carbohydrates during the run to maintain energy levels. This can be done through sports drinks, gels, or chews that contain easily digestible carbohydrates, such as glucose or fructose. It is important to test out different fueling options during training runs to see what works best for your body and to avoid stomach discomfort during the race.
In addition to carbohydrates, it is also important to stay hydrated during the run. Aim to consume 16-20 ounces of water or sports drink per hour of running, and be sure to listen to your body and drink more if you feel thirsty.


After your run, it is important to refuel your body with carbohydrates and protein to help replenish lost energy and repair damaged muscle tissue. Ideally, you should consume a snack or meal within 30 minutes of finishing your run to optimize recovery. Good post-run snack options include a banana with peanut butter, a protein shake, or a turkey sandwich on whole-grain bread.

It is also important to continue to hydrate after your run, as dehydration can lead to muscle cramping and fatigue. Aim to consume at least 16-20 ounces of water or sports drink for every pound of weight lost during your run.


While a well-balanced diet should provide all of the nutrients and energy that endurance runners need, some supplements can be beneficial for performance and recovery. These include:
CAFFEINE: Caffeine has been shown to enhance endurance performance by reducing the perception of effort and increasing fat utilization for energy. It is recommended to consume caffeine 30-60 minutes before the run in the form of coffee, tea, or a sports drink that contains caffeine.
BETA-ALANINE: Beta-alanine is an amino acid that has been shown to increase muscle endurance and delay fatigue. It is recommended to take beta-alanine supplements for at least 4-6 weeks before the race to see benefits.
IRON: Iron is essential for the production of hemoglobin, which carries oxygen to our muscles. Endurance runners, especially females, are at a higher risk for iron deficiency, which can lead to fatigue and decreased performance. Iron supplements may be recommended for those with low iron levels.
It is important to note that supplements should not be used as a replacement for a healthy, balanced diet, and should only be taken under the guidance of a healthcare professional.


Proper nutrition and fueling strategies are essential for endurance runners to optimize performance and sustain energy levels throughout their runs. Endurance runners should consume a well-balanced diet that includes carbohydrates, protein, and healthy fats, as well as stay hydrated before, during, and after their runs. Additionally, supplements such as caffeine, beta-alanine, and iron may be beneficial for performance and recovery, but should only be taken under the guidance of a healthcare professional.
Remember, every runner is unique and what works for one person may not work for another. It is important to experiment with different fueling strategies during training runs to find what works best for your body.
