No matter if you desire to enhance your running abilities or simply sustain your current routine, it is vital to prioritize your diet. Food serves as fuel for all runners.
Your energy levels and performance can be greatly influenced by the types of food you decide to consume. Additionally, these food choices can aid in minimizing the likelihood of experiencing digestive problems during your runs. Whether you engage in extensive marathon running or simply enjoy a quick jog around your local area, it is essential to have knowledge about the appropriate foods to eat, as well as the optimal timing for consuming them, in order to optimize your performance and well-being.
This article delves extensively into the top diet for runners and the ways in which nutrition can improve your performance.
When to eat
Knowing what to eat and when is a crucial aspect of fueling for long runs.
Prior to a workout, it is beneficial to engage in pre-activity preparations.
It is recommended to consume a meal rich in nutrients a few hours prior to your training session. Ensure that your pre-workout meal includes all three essential macronutrients, with an emphasis on carbohydrates to provide energy. Although fiber is beneficial, consuming high-fiber foods beforehand may result in potential gastrointestinal discomfort or a need to use the restroom. Consider trying some nutritious meals specifically tailored for pre-running activities.
- Whole wheat pasta with grilled chicken
- Whole grain bagel with low-fat cheese, avocado, or tomato
- Eggs and whole wheat toast
- Whole wheat toast with peanut butter and banana
If you prefer to run earlier in the day, it is still necessary to have a light snack for energy. Choose a snack that is easy to digest and contains carbohydrates for fuel. Good options include a banana, energy bar, or whole-grain bagel, as they provide the necessary carbohydrates to sustain a long run.
During the process of training
If you plan to run for an hour or two, a sports drink should suffice to sustain your energy. However, marathon nutrition experts advise consuming fuel if your running duration extends from three to five hours. Carbohydrate gels are favored snacks among long-distance runners and marathon participants as they provide carbohydrates to replenish energy and are easily digestible.
After completing the training
To aid in muscle recovery and replenish energy for future sessions, it is beneficial to eat after training. It is recommended to consume a recovery snack or meal within 15 minutes to an hour after training, accompanied by water or a sports drink to rehydrate. A suitable recovery meal might consist of options such as a lean protein with vegetables and brown rice, a whole wheat bread sandwich, or a bowl comprising rice, cheese, avocado, and salsa.
What to eat the night before a long run
On the day prior to a marathon, half-marathon, or any other long distance run, it is advisable to have a plan for continuous eating. Opt for consuming multiple small meals during the day that are rich in carbohydrates. Relying on a single substantial carbohydrate-rich meal before the race will not provide you with the necessary energy.
Typically, runners tend to have a more relaxed training schedule during the week leading up to a long race. However, it is still important to maintain consistent meals and portions. In the days preceding the race, prioritize carbohydrates in order to replenish your glycogen stores.
In the morning of a race, it is common to experience a slight nervousness and reduced appetite. However, it is important to consume a minimum amount of food to energize yourself. A suitable choice could be a protein smoothie, oatmeal, or granola bar. It is advisable to have your pre-race breakfast a few hours prior to running.
Nutrition basics for runners
In order to shop for optimal foods for running, it is crucial to have an understanding of the science behind them. The three macronutrients that play a significant role in your overall diet are:
- carbohydrates
- fat
- protein
In addition, the consumption of a varied range of foods will guarantee that you also receive micronutrients and antioxidants, which have a vital role in the function and recovery of muscles.
Carbohydrates
Carbohydrates play a vital role as the primary source of energy for the body, particularly during long-distance running. Upon consumption, dietary carbohydrates are broken down by the body into glucose, which is their basic sugar form.
Glucose plays a crucial role in providing energy for humans. This is due to its necessity in the production of adenosine triphosphate (ATP), the currency of energy in cells. When engaged in physical activity like running, glucose may be directed to muscle cells as an instant energy supply. Any excess glucose in the blood is then transported to the liver and muscle cells for storage as glycogen.
First, while running, your body consumes glucose from the bloodstream to fuel active muscles. Then, as glucose levels start to decline, the body initiates glycogenolysis, a process in which stored glycogen is converted back into glucose. Furthermore, your VO2max represents the peak oxygen utilization rate during physical activity and rises in correlation to the intensity of exercise.
The limited oxygen availability causes your body to switch to anaerobic energy production, which predominantly relies on carbohydrates. When you increase the intensity of your exercise, like during short distance runs and sprints, your body primarily utilizes carbohydrates as fuel and uses fat as a secondary source.
Because a sprint is a shorter duration activity, most individuals will have enough blood glucose and glycogen stores to sustain their run. However, during longer runs of lower intensity, the body starts to depend more on fat stores for energy production. This change typically occurs when the distance surpasses 6 miles (10 km).
In addition to this, the majority of long-distance runners will require simple sugars to replenish their energy during a run. This is why many long-distance runners choose to consume sports beverages or energy gel. It is recommended that most runners aim to obtain approximately 45-65% of their total daily calorie intake from carbohydrates.
Fat
Stored body fat is a great fuel source, particularly for lengthy runs. It is generally recommended to consume around 20–30% of your daily calories from predominantly unsaturated fats. It is advised to avoid consuming less than 20% of your calorie intake from fat.
Deficiencies in fat-soluble vitamins and essential fatty acids are associated with a low intake of fat. When engaging in endurance exercise for an extended period, the body utilizes its fat reserves as the main energy source. This occurs via fat oxidation, where stored triglycerides are broken down into fatty acids that are converted into glucose by the body.
Although fat oxidation is beneficial for long-distance running, it is not as efficient for high intensity exercise compared to using carbohydrates because the conversion of fat into energy takes more time and also necessitates oxygen.
Additionally, when it comes to fueling your workout, carbohydrates are more efficient than dietary fat as they are readily available and quickly utilized during exercise. Therefore, instead of relying on fat consumption for energy during running, it is advisable to include it as part of a well-balanced diet to support your body’s overall functions.
Dietary fat plays a pivotal role in:
- healthy joints
- hormone production
- nerve function
- general health
In addition to being a vital part of your diet, it aids in the absorption of fat-soluble vitamins (A, D, E, and K). For those who encounter stomach discomfort, it is advisable to consume meals with lower fat content prior to a run. Conversely, it is recommended to consume meals with higher fat content during the recovery period.
Protein
Instead of being a primary source of fuel during endurance exercise, protein is utilized by your body to provide support for:
- muscle growth and regrowth
- tissue repair
- injury prevention
- the production of oxygen-carrying red blood cells
- overall recovery
To rebuild the muscles broken down while running, it is essential to refuel with protein since the muscles cannot efficiently rebuild without it. The lack of protein can result in muscle wasting, higher susceptibility to injury, and decreased performance.
While the amount of protein needed varies for each person, studies generally recommend consuming approximately 0.6–0.9 grams of protein per pound (1.4–2.0 grams per kg) of body weight daily. This intake is considered adequate for recovery and may assist in preventing muscle loss among exceptionally high endurance athletes.
Micronutrients
Exercise puts pressure on your body’s metabolic pathways, thus requiring a diet high in micronutrients to ensure their optimal function. While the specific needs may vary for each athlete, certain micronutrients hold particular significance.
- Calcium. This is a main player in bone health and muscle contraction. Most people consume enough in their diet from calcium-rich foods, including dairy products and leafy greens.
- Vitamin D. Vitamin D is important for bone health because it supports calcium and phosphorus absorption. It may also contribute to muscle metabolism and function. You can get it from sun exposure, supplements, and vitamin-D-rich foods.
- Iron. This is crucial for the development of red blood cells, which deliver oxygen to working muscle cells. Distance runners, vegetarians, and vegans may need higher than the recommended dietary intake — greater than 18 mg per day for women and 8 mg per day for men.
- Antioxidants. Antioxidants help decrease cell damage caused by oxidation from intense exercise. Consuming antioxidant-rich foods — like vegetables, fruit, nuts, seeds — seems to be more effective than taking antioxidant supplements.
- Other nutrients and aids. Many athletes may use supplements or consume foods to enhance performance, such as beetroot, caffeine, beta-alanine, and carnosine. Some of these are backed by more research than others.
Ensuring that you consume a diverse selection of whole foods will guarantee that you obtain an adequate amount of micronutrients for the majority of individuals.
