There is often a lot of focus on what to eat before a marathon, but what to eat after a marathon is equally important.
Although what you eat after a marathon certainly won’t impact your performance in the race, it can have a significant impact on your ability to recover and get back to training once it is time to do so.
Studies have found that what you eat immediately after a marathon can have a significant impact on the amount of muscle soreness and recovery that you experience within the first 72 hours after the race.
In this article, we will discuss what to eat after a marathon, both in terms of immediately in your post-marathon meal and as well as what to eat the week after a marathon.
We will cover:
- What Should You Eat After a Marathon?
Let’s dive in!
What Should You Eat After a Marathon?
There are three primary components of what to eat after a marathon: replenishing your glycogen stores, restoring your fluid and electrolyte balance, and providing nutrients to repair muscle damage.
Let’s look at each of these aspects of post-marathon nutrition individually and how they affect what to eat after a marathon.
Replenishing Glycogen Stores
One of the most important nutritional goals of your post-marathon meal is to start replenishing your glycogen stores.
Glycogen is the storage form of carbohydrates in the body, and it is stored in the muscles and liver.
When you run a marathon, even if you do a good job fueling with carbohydrate-rich foods and sports drinks during the marathon, you will deplete your glycogen stores entirely or almost entirely.
Carbohydrates are burned to provide the energy that you need during your marathon.
It is important to replenish your glycogen stores as soon as possible after your marathon in your first post-marathon snack or meal. It will take time to replenish all of your glycogen fully, so you want to have a carbohydrate-rich snack as soon as possible.The standard recommendation for carbohydrate refueling after exercise is to consume 0.6–1.0 g/kg carbohydrate within 30 min and again every 2 hours for the next 4–6 hours.
There are quite a number of high-carbohydrate foods that can be used to start replenishing glycogen in your post-marathon meal.
- Whole grains, such as quinoa, rice, whole wheat pasta, buckwheat, and teff, are all high in carbohydrates and can be excellent options for your post-marathon meal.
These types of whole grains contain about 25 to 40 grams of carbohydrates per cup, depending on the type of grain.
- You may also want to have whole-grain tortillas, whole-wheat bread, or whole-grain cereals if your post-marathon meal is brunch or lunch.
- Sweet potatoes are another excellent option for your post-marathon meal.
They are rich in complex carbohydrates and packed with vitamins and minerals such as vitamin A, vitamin C, and vitamin E. These antioxidants will help fight inflammation and oxidative damage from your marathon, which can potentially reduce muscle soreness and help you recover.
- Regular white potatoes are also among the best foods to eat after a marathon.
They are high in carbohydrates as well as potassium, which will help replenish the potassium lost in sweat.
- Another great option for replenishing glycogen after a marathon is legumes such as lentils, beans, chickpeas, and split peas.
These foods provide complex carbohydrates and fiber, and also a decent amount of plant-based protein, and protein can facilitate glycogen resynthesis.
- Some of the best post-marathon snacks that are rich in carbohydrates include fruits such as bananas, berries, and cherries or dried fruits such as dried apricots, cranberries, raisins, and dried pineapple. Dried fruit and bananas are particularly high in carbohydrates.
Fruits like bananas and apricots are rich in potassium, which will help you start replenishing the electrolytes that you have lost in sweat.
Berries and cherries are very high in antioxidants such as anthocyanins, vitamin C, and even vitamin E. These antioxidants and polyphenols can help fight inflammation and oxidative damage from the stress and strain of the marathon.
Right after your marathon is over, you will likely not have the appetite or stomach for a full meal. Still, it is important to start consuming carbohydrates within 15 to 30 minutes after finishing the marathon.
If you really have no appetite at all, do your best to start getting some carbohydrates by way of sports drinks.
Replenishing Fluid and Electrolytes
You sweat a lot during a marathon, and even if you do a decent job hydrating during the race, you will likely be somewhat dehydrated and depleted in terms of your electrolytes after the marathon.
Make sure to drink plenty of fluids. Although many runners prefer drinking water, if you are not able to do a lot of eating after the marathon, you should be drinking sports beverages or electrolyte drinks to replenish the electrolytes lost.
If you are able to eat after the marathon, you can focus on having hydrating and electrolyte-rich foods.
Examples include fruits such as watermelon, berries, cantaloupe, honeydew, oranges, clementines, peaches, coconut water, and vegetables like leafy greens.
Hydrating foods also include watery vegetables such as pickles, cucumbers, and tomatoes.
Other foods that are great to incorporate in your post-marathon meal due to the high natural electrolyte content include:
- Avocados and potatoes, which are extremely rich in potassium
- Nuts and seeds, which have a lot of magnesium
- Milk and dairy products, which have an array of electrolytes
- Sodium-rich foods such as eggs, spinach, poultry and fish, and salted nuts
Consuming Nutrients to Support Marathon Recovery
It is very important to eat protein after a marathon, particularly one of the main components of what to eat the week after a marathon.
Unlike shorter runs and lower-intensity runs, running a marathon actually burns a significant amount of protein. Up to 15% of the calories that you burn in a marathon may come from proteins, as protein metabolism increases significantly when glycogen stores are low.
Additionally, even though protein may not have been the primary source of fuel during the marathon, your muscles need protein after a marathon to help repair muscle damage to stay on the run.
Studies have found that the best post-marathon fueling strategy is to combine carbohydrates with protein, as this mix of nutrients helps facilitate muscle repair and recovery and glycogen resynthesis.
The body only has a limited ability to absorb protein at one time. Therefore, it is best to spread out protein consumption in dosages of about 20 to 25 grams every four hours rather than to consume a ton of protein all at once.
For this reason, studies have demonstrated that ingesting 20 grams of protein immediately after exercise and then every three hours for the next 12 hours increases the rate of muscle protein synthesis more than having more protein less frequently (for example, 40 grams every six hours).
Many marathon runners opt for a protein bar right after the race because most protein bars provide a good balance of carbohydrates and proteins and are often easier to stomach than a whole foods-based option.
Once you are ready for your post-marathon meal, choose protein-rich foods such as lean meat, fish, poultry, dairy, or soy.
A serving of chicken breast provides about 31 grams of protein.
Tuna fish packs about 19 grams of protein per serving. Low-fat Greek yogurt and cottage cheese are packed with proteins, each providing about 24 grams per cup.
Even some whole grains are decent sources of protein. For example, quinoa provides about 8 grams of protein per cup, and you’ll also be getting about 24 grams of carbohydrates to start replenishing glycogen.
Lastly, it can be helpful to incorporate anti-inflammatory foods into your diet after a marathon.
Your body sustains quite a bit of muscle damage, and studies have found that inflammatory markers are significantly elevated after a marathon.
Reducing inflammation after a marathon may help facilitate recovery and decrease muscle soreness.
Examples of anti-inflammatory foods include foods high in omega-3 fatty acids, such as salmon, other fatty fish, flaxseeds, and nuts.
Foods high in antioxidants and polyphenols can also reduce inflammation.
Examples Include such as green leafy vegetables, berries, tomatoes, papaya, pineapple, tart cherries, pomegranate, avocado, broccoli and other cruciferous vegetables, green tea, dark chocolate, nuts such as almonds and walnuts, squash and pumpkin seeds, flax seeds, chia seeds, and legumes.
Overall, what you eat after a marathon is extremely important for proper recovery.
Although you should definitely feel free to indulge in whatever food you are craving, it is crucial to make sure that you are also focusing on your nutrition and refueling your body with plenty of nutritious foods and hydrating fluids.
