Why Eating Well Before a (Half) Marathon Is Important
Eating well helps your body handle long distances. It provides energy, supports better performance, and helps your body recover faster during and after a (half) marathon.
1. More energy
Your body mainly uses carbohydrates as fuel while running. By eating proper food before a marathon, you’ll have enough energy to keep going for longer.
2. Less fatigue
If you don’t eat enough, you’ll get exhausted more quickly. Good nutrition helps prevent sudden energy crashes.
3. Better performance
With the right nutrition you can:
- maintain a good pace for longer
- get tired less quickly
- perform better overall
4. Faster recovery
After a (half) marathon, your muscles need time to recover. Nutrition that contains protein and carbohydrates helps your muscles repair and rebuild. 💪
What to eat before a marathon
A marathon requires more energy over a longer period of time than a half marathon. That’s why it wouldn’t make sense to give the same nutrition advice for both distances. Below, we explain what to eat leading up to a marathon or half marathon.
What to eat prior to a marathon
Running a marathon puts a huge demand on your body, especially if you’re tackling an Iron Viking. In the days leading up to the marathon, it’s wise to pay extra attention to carbohydrates.
Days before:
By eating more carbohydrate-rich foods such as pasta, rice, potatoes, and bread, you replenish the glycogen stores in your muscles. This process is also known as carb loading.
Morning of the marathon:
On race day, it’s best to choose a light, easily digestible meal high in carbs and low in fat and fiber. Examples include:
- White bread or a bagel with jam or honey
- Oatmeal with banana
- Yogurt with muesli
- A banana or other piece of fruit
Try to eat this meal about 2 to 3 hours before the marathon, giving your body enough time to digest.
During the marathon:
Eating during the marathon is recommended. It helps maintain energy levels with extra carbohydrates, for example via energy gels, sports drinks, or energy bars. Many runners consume small amounts of carbs every 30 to 45 minutes to keep their energy steady.
After the marathon:
Proper recovery after a marathon is extremely important. A combination of carbohydrates and protein helps replenish energy stores and repair muscles. Options include chocolate milk (it works!), yogurt with fruit, or a meal with rice, vegetables, and a protein source like chicken, fish, or tofu.
What to eat leading up to a half marathon
For a half marathon (21 km), many of the same principles apply as for a full marathon, but since the distance is shorter, you don’t need to adjust your nutrition as heavily. The focus is mainly on having enough energy and a light stomach during the race. Let’s see what to eat before a half marathon.
Days before:
You don’t need extensive carb loading like for a full marathon. Still, eat regular carbohydrate-rich meals such as pasta, rice, potatoes, whole-grain bread, and fruit to keep your energy stores topped up.
Morning of the half marathon:
Choose a light, easily digestible meal 1.5 to 2 hours before the half marathon. Examples:
Oatmeal with banana or apple
White bread or a bagel with jam or honey
A banana or other piece of fruit
Avoid large amounts of fat or fiber, as these slow digestion.
During the half marathon:
Extra food is usually not strictly necessary since the effort is shorter than a full marathon. You can bring water or a sports drink, especially in warm weather or if you notice you get thirsty quickly.
After the half marathon:
Recovery is important, but less intensive than after a full marathon. Eat a combination of carbohydrates and protein to help your muscles recover and replenish energy. Examples:
Yogurt with fruit and granola
Whole-grain bread with peanut butter
Smoothie with fruit and (plant-based) milk
In Short
Whether you’re running a half or full marathon, or taking part in an event like Strong Viking or STYREKX, nutrition plays a crucial role in your performance and recovery. Focus on easily digestible meals that keep your energy levels steady, with enough carbohydrates to fuel your muscles. Don’t forget to stay well hydrated before, during, and after your effort. By eating and drinking smartly, you can maximize your energy and get the most out of your athletic challenge.
