Marathon training is a challenging journey that requires dedication, perseverance, and discipline. As a marathon runner, you need to fuel your body with the right nutrients to perform at your best and prevent injuries. However, with so much conflicting information about nutrition, it can be overwhelming to know what to eat and what to avoid. That’s why in this blog post, we’ve compiled seven top tips for healthy eating while marathon training. These tips will help you create a balanced, nutrient-dense, and enjoyable diet that supports your performance and recovery. Whether you’re a seasoned marathon runner or a newbie, these tips will help you optimise your nutrition for the best marathon experience. So, let’s dive in and discover how to eat healthily while marathon training.
1. Eat a Balanced Diet
A balanced diet is a diet that provides all the necessary nutrients in the right amounts to support good health and well-being. A balanced diet includes a variety of foods from all the food groups, including carbohydrates, proteins, fats, vitamins, and minerals. If you’re aiming for healthy eating while marathon training, then keeping things balanced is a great start.
Consuming a variety of foods is important because each food group provides a unique set of nutrients that our bodies need to function properly. For example, carbohydrates provide energy, protein helps build and repair muscles, fats are important for hormone production and vitamin absorption, and vitamins and minerals play a role in many essential bodily functions. By eating a variety of foods, we ensure that we are getting all the nutrients we need to support our bodies’ needs.
Additionally, consuming a variety of foods can help prevent boredom with our diets, making it more likely that we will stick to healthy eating habits. Eating the same foods every day can become monotonous, and we may be more likely to turn to unhealthy options out of boredom or lack of variety.
Examples of balanced meals include:
- Grilled chicken breast with brown rice and steamed vegetables (carbohydrates, protein, vitamins, and minerals)
- Quinoa salad with mixed greens, roasted vegetables, and avocado (carbohydrates, protein, healthy fats, vitamins, and minerals)
- Whole wheat pasta with tomato sauce, lean ground beef, and a side of garlic bread (carbohydrates, protein, healthy fats, vitamins, and minerals)
- Grilled salmon with roasted sweet potato wedges and a side of green beans (protein, healthy fats, carbohydrates, vitamins, and minerals)
Overall, a balanced diet with a variety of foods is crucial for maintaining good health and fueling the body during marathon training.
2. Focus on Nutrient-Dense Foods
Nutrient-dense foods are foods that are high in nutrients relative to their calorie content. In other words, they are foods that provide a lot of essential nutrients, such as vitamins, minerals, protein, fibre, and healthy fats, while containing relatively few calories. Nutrient-dense foods are often whole, unprocessed foods, such as fruits, vegetables, whole grains, lean proteins, and healthy fats.
The importance of consuming nutrient-dense foods for healthy eating while marathon training is that they provide the body with the necessary nutrients it needs to function properly without adding unnecessary calories. Consuming a diet rich in nutrient-dense foods can help improve overall health, reduce the risk of chronic diseases, and promote weight loss.
In contrast, consuming foods that are low in nutrients and high in calories, such as processed foods, sugary drinks, and fried foods, can lead to weight gain and increase the risk of chronic diseases, such as heart disease, diabetes, and certain cancers.
Examples of nutrient-dense foods include:
- Dark leafy greens, such as spinach and kale, which are high in vitamins A, C, and K, iron, and calcium.
- Berries, such as blueberries, raspberries, and strawberries, which are high in antioxidants and vitamin C.
- Nuts and seeds, such as almonds, walnuts, chia seeds, and flaxseeds, which are high in healthy fats, fibre, and protein.
- Whole grains, such as brown rice, quinoa, and whole wheat bread, which are high in fibre, B vitamins, and minerals.
- Lean proteins, such as chicken, fish, and tofu, which are high in protein, iron, and other essential nutrients.
In conclusion, consuming a diet rich in nutrient-dense foods is important for maintaining good health and fueling the body during marathon training. Incorporating a variety of nutrient-dense foods into meals and snacks can help ensure that the body is getting all the necessary nutrients it needs to perform at its best.
3. Eat Adequate Amounts of Carbohydrates
Carbohydrates are one of the three macronutrients, along with protein and fat. They are the primary source of energy for the body and are crucial for runners because they provide fuel for the muscles during exercise. Carbohydrates are broken down into glucose, which is stored in the muscles and liver as glycogen. During exercise, the body uses glycogen to fuel muscle contractions.
Carbohydrate-rich foods include:
- Whole grains, such as brown rice, whole wheat bread, and oatmeal
- Fruits, such as bananas, apples, and oranges
- Vegetables, such as sweet potatoes, corn, and peas
- Legumes, such as lentils, chickpeas, and kidney beans
- Dairy products, such as milk and yoghurt
- Sports drinks, gels, and bars
Tips for incorporating carbohydrates into meals and snacks include:
- Choose whole grain versions of bread, pasta, and rice, which are higher in fibre and nutrients than their refined counterparts.
- Include a serving of fruit or vegetables with every meal and snack.
- Add beans or lentils to soups, stews, and salads for an extra source of carbohydrates and protein.
- Make smoothies with fruit, yoghurt, and a scoop of protein powder for a quick and easy carbohydrate-rich snack.
- Use sports drinks, gels, and bars during long runs to help maintain energy levels.
It’s important to note that the amount of carbohydrates needed varies depending on the individual and their training needs. It’s recommended that for healthy eating while marathon training runners aim to consume 3-12 grams of carbohydrates per kilogram of body weight per day, depending on the duration and intensity of their training. Consulting with a registered dietitian can help runners determine their individual carbohydrate needs.
4. Get Enough Protein
Protein is a macronutrient that is essential for building and repairing tissues in the body, including muscles, bones, and skin. Protein is important for runners because it helps to repair and rebuild muscle tissue that is damaged during exercise. Protein is also important for immune function, hormone production, and maintaining fluid balance in the body.
Protein-rich foods include:
- Lean meats, such as chicken, turkey, and fish
- Eggs and egg whites
- Dairy products, such as milk, cheese, and yoghurt
- Legumes, such as lentils, beans, and chickpeas
- Nuts and seeds, such as almonds, peanuts, and sunflower seeds
- Soy products, such as tofu and tempeh
Tips for incorporating protein into meals and snacks include:
- Aim to include a source of protein with every meal and snack.
- Choose lean protein sources, such as chicken, fish, and tofu, to reduce the intake of saturated fat.
- Add nuts or seeds to salads, yoghurt, or smoothies for an extra source of protein and healthy fats.
- Make a protein-rich snack by pairing a hard-boiled egg with a piece of fruit or vegetable.
- Plan ahead by preparing protein-rich meals and snacks in advance, such as boiled eggs or roasted chickpeas.
It’s important to note that the amount of protein needed varies depending on the individual and their training needs. It’s recommended that runners aim to consume 1.2-2 grams of protein per kilogram of body weight per day, depending on the intensity and duration of their training. Consulting with a registered dietitian can help runners determine what healthy eating while marathon training is needed.
5. Don’t Forget about Healthy Fats
Healthy fats are a type of nutrient that are essential for maintaining good health. They play a role in hormone production, cell function, and brain health, among other things. For runners, healthy fats can also help to provide a source of energy and promote satiety, which can help to prevent overeating.
Healthy fat sources include:
- Avocado
- Nuts, such as almonds, walnuts, and cashews
- Seeds, such as chia, flax, and pumpkin seeds
- Fatty fish, such as salmon, mackerel, and sardines
- Olive oil, avocado oil, and other plant-based oils
- Nut butters, such as almond or peanut butter
Tips for incorporating healthy fats into meals and snacks include:
- Use olive oil or avocado oil for cooking instead of butter or margarine.
- Add a handful of nuts or seeds to salads, oatmeal, or yoghurt for an extra source of healthy fats.
- Make a snack by pairing apple slices with almond butter or celery sticks with hummus.
- Include fatty fish, such as salmon or tuna, in meals at least twice a week.
- Top vegetables with a drizzle of olive oil or a sprinkle of nuts or seeds for added flavour and nutrition.
It’s important to note that while healthy fats are important, they are also high in calories, so it’s important to consume them in moderation as part of a balanced diet. Aiming to consume 20-35% of daily calories from healthy fats is generally recommended. Consulting with a registered dietitian can help runners determine their individual needs for healthy fats and how to incorporate them into their diet.
6. Stay Hydrated
Hydration is critical for runners, as proper fluid balance helps to regulate body temperature, transport nutrients, and remove waste from the body. During marathon training, it’s particularly important to stay hydrated, as dehydration can lead to decreased performance, muscle cramps, and even heat stroke in extreme cases.
Tips for staying hydrated during marathon training include:
- Drink water throughout the day, aiming for at least 8-10 cups per day.
- During training, drink 4-8 ounces of water or sports drink every 15-20 minutes.
- Monitor urine color to ensure adequate hydration – a pale yellow color is a good indication of proper hydration.
- Weigh yourself before and after exercise to gauge fluid loss, aiming to replace lost fluids with water or sports drinks.
- Consider using a sports drink during prolonged exercise to replace electrolytes lost through sweat.
Hydrating beverages include:
- Water – still or sparkling
- Sports drinks, which can provide electrolytes lost through sweat
- Coconut water, which contains natural electrolytes
- Milk and milk alternatives, such as soy or almond milk
- Fruit juices, although these should be consumed in moderation due to their high sugar content
It’s important to note that caffeine and alcohol can actually dehydrate the body, so it’s best to limit consumption of these beverages during marathon training. Additionally, individual hydration needs can vary based on factors such as temperature, humidity, and individual sweat rates, so it’s important to listen to your body and adjust fluid intake accordingly.
7. Plan Ahead
Planning ahead when it comes to meals can be extremely beneficial, particularly for busy runners who may not have the time or energy to prepare meals from scratch every day. Some benefits of planning ahead include:
- Saves time: Meal planning and preparation can help to save time in the long run, as meals can be prepared in advance and ready to go when needed.
