Marathon

Marathon is a challenging sport, and in order to perform your best and have the energy to last the entire marathon, what you eat before the race is very important. What goes in your body sets the tone of your marathon. So, eat properly and hydrate to replenish glycogen stores to avoid weariness and get closer to that medal you have been eyeing. The best pre-marathon meal should consist of nutrient-dense, easily digested foods that release energy gradually and do not hold you back. When taken at the appropriate time prior to the race, a combination of complex carbs, moderate protein, and low fat will help you stay energised and prevent any cramps while running. Let's go over the best foods to eat before a marathon, when to eat them, and what to avoid to guarantee that medal!

      What To Eat Before A Marathon?

      Here are the food groups, along with a list of foods under each you can eat before a marathon:

        1. Carbohydrates

        Carbohydrates are the key elements that are converted into glucose, essential for maintaining energy levels. I know the days leading up to the marathon are when the final preparations are in full swing. You may increase endurance, maximise glycogen availability, and sustain a steady performance by giving carbs priority in your pre-marathon meals.

          Here are the carbs you can rely on:

          Note: Your energy levels may rapidly decline if you don't have enough glycogen, which could cause early fatigue and poor performance. So, carbohydrates are a must!

          • Days Leading Up To The Race: Brown rice, quinoa, whole grains, sweet potato and oats
          • Day Before The Race: White rice, white bread, potatoes, and fruit juices.
          • 3-4 Hours Before The Race: Bananas, porridge or oatmeal with honey drizzles, rice cakes with nut butter and low-fat yoghurt with granola.
          • 30-60 Minutes Before The Race: Energy drinks, electrolytes and water.

          2. Protein

          Protein ensures that your muscles remain primed and prepared for the lengthy exertion your body is going to witness. No wonder you would need to rely on additional protein as by the time you reach the ultimate destination of your training, i.e. Race Day, your muscles tend to soar. But we can’t let that affect your chances of winning the medal.

            Here’s the kind of protein you would need: Note: Consuming enough protein prior to the marathon helps speed up recovery and reduce post-race muscle discomfort or fatigue, enabling you to recover more quickly.

            • Days Leading Up To The Race: Grilled chicken, eggs, fish, yoghurt or any low-fat dairy, paneer and tofu
            • Day Before The Race: Chicken with rice, greek yoghurt with honey and granola, egg sandwich with white bread and protein smoothie with your favourite protein powder.
            • 3-4 Hours Before The Race: Plain Greek yoghurt, egg white, chicken slices and a small quantity of nut butter.
            • 30-60 Minutes Before The Race: Protein bar with 10-15gm or protein and hard-boiled egg.

            3. Easy-To-Digest Fruits

            Simple carbs, which are abundant in fruits like bananas, oranges, and berries, are quickly transformed by the body into glucose for instant energy. Your glycogen levels will be at their maximum if you eat foods high in carbohydrates in the hours before the marathon. This will provide you with a consistent source of energy during the race.

              Here is a list of fruits you can have while prepping for the marathon:

              Note: It’s better if you consume the fruit itself. You can consume freshly squeezed juices for convenience but prefer having them without any kind of sugar syrups.

              • Bananas: Eat a whole banana 30-60 minutes before the race for a quick energy boost. You can also add a small quantity of peanut butter to it as a required source of protein.
              • Apples: Eat one small peeled apple 1-2 hours before the race.
              • Watermelon:A small bowl of watermelon an hour before the race will help you stay hydrated and give you the required energy boost.
              • Oranges: Packed with vitamin C, eat a small orange 30-60 minutes before the race or drink a small glass of fresh orange juice.
              • Kiwis: 2 peeled kiwis 1-2 hours before the race as a quick energy-boosting snack.
              • Berries: A handful of strawberries, raspberries and blueberries or ½ cup of these berries an hour before the race.
              • Pineapple: ½ cup pineapple 30-60 minutes before the race can help alleviate any kind of digestive discomfort.

              4. Hydration

              You can maintain your effort over long-distance runs by starting the race well-hydrated, which reduces the chance of weariness, cramping in your muscles, and overheating. Electrolytes like sodium, potassium, and magnesium are lost through perspiration and are necessary for muscular function and cramp prevention. Just before the race, drinking too much plain water might dilute electrolytes and produce hyponatremia or low sodium levels, which can make you weak or confused. Instead of consuming a large amount all at once, sip on water or an electrolyte-enhanced beverage in the hours leading up to the marathon.

                5. Essential Pre-Marathon Nutrition Tips

                Here are helpful tips on what to eat before a marathon and even what needs to be avoided:

                  1. Increase Energy Source

                  Since your body uses carbohydrates as its main fuel source for endurance exercises, eating them before a marathon is essential. Carbohydrates are converted to glucose and stored as glycogen in the liver and muscles. These glycogen stores play a key role in your body's ability to maintain energy levels and power your muscles over extended distances throughout a marathon.

                    2. Add Moderate Protein For Muscle Support

                    Protein is essential for supporting muscles before a marathon as it helps with muscle maintenance, repair, and recovery. Moderate protein consumption before a marathon lowers the chance of muscle breakdown throughout the run by preserving muscle tissue integrity. Additionally, it contains amino acids, which are necessary for healing muscle microtears that may develop during extended training sessions before the marathon. When combined with carbohydrates, protein helps maintain steady energy levels.

                      3. Indulge In Natural Sugars

                      Fruits that are easy to digest and contain natural sugars are a great pre-marathon option since they provide a rapid and effective energy boost without any additional burden on the digestive tract. Fruits are rich in vitamins, minerals, and water, which improve overall performance and reduce weariness, in contrast to processed sugary diets.

                        4. Time Your Meals

                        It's important to plan your meals before a marathon in order to maximise energy levels, avoid stomach pain, and perform at your best during the run. Your body will have enough time to digest and transform the nutrients into useful energy if you eat a well-balanced meal three to four hours prior to the marathon. You can't afford to feel bloated or lethargic. Eating too soon before the race might cause cramps, pain, or decreased performance since your body may still be breaking down food when the marathon starts, rerouting blood flow from your muscles to your digestive system. One to two hours prior to the marathon, a little snack can provide you with an extra energy boost. While the snack gives you rapid energy without filling your stomach, timing your meals in this manner guarantees that your body has completely digested and absorbed the nutrients from the main meal.

                          5. Stay Hydrated

                          Hydrate and repeat! For best results, stay hydrated before a marathon because even slight dehydration can have a big effect on your strength, focus, and endurance. Maintaining a healthy fluid balance is essential for controlling body temperature, promoting cardiovascular health, and providing oxygen and nutrients to your muscles.

                            6. Avoid Certain Foods

                            Foods that can upset your stomach, lower your energy or impair your performance should be avoided right before a marathon. These foods mentioned below might cause stomach pain, bloating, or nausea because they take longer to digest in the stomach, which makes it more difficult to keep up:

                              • Fatty And Fried foods: Creamy dips, fried chicken, french fries, etc.
                              • High-fibre meals: Beans, whole grains, and cruciferous vegetables (like broccoli and cauliflower).
                              • High-Sugar Foods: Cookies, pastries, candies, sugary sodas and energy drinks.
                              • Spicy foods: Spicy chilli, curries, hot wings, hot sauce, etc.
                              • Carbonated Drinks: Fizzy energy drinks, sodas, sparkling water, etc.
                              • Avoid alcohol, Fast food, salty chips and pickled foods.
                              • Avoid dairy products if they cause digestive discomfort or do not sit well with your stomach.

                              The Final Say

                              Your pre-marathon diet is crucial to ensure that you have the stamina, energy, and concentration required to give it your all. Eating a balanced pre-race meal three to four hours prior to the race, which is high in complex carbs, moderate protein, and low in fat, ensures a consistent release of energy during the race. Your performance will be further improved by snacking on the right foods at the right time, drinking enough water, and avoiding foods that can make you uncomfortable, such as those high in fat, fibre, or spice. By carefully planning and scheduling your meals, no one can stop you from getting that medal. Go get it!
