The half marathon is a tricky distance when it comes to fuelling. While it's true that you can get through a 13.1-mile run without taking on extra carbs, you are unlikely to perform at your best and you may struggle towards the end when your energy levels deplete. The right nutrition plan is the one that works for you and doesn't give you an upset stomach. While some prefer gels, others go with chews or whole foods. Carbohydrates are essential for fuelling before a half marathon, and runners should aim for 30-90g of carbs per hour during the race.

What You'll Learn
Carbohydrates, fluids, and electrolytes
Carbohydrates are essential for fuelling your body during a half marathon. They provide a quick, readily available source of energy for your muscles and other vital organs. The general rule of thumb is to fuel for any run lasting longer than 70 minutes. However, the amount of carbohydrates you need depends on factors such as the intensity of the run, the athlete's size, experience, and gastrointestinal tolerance.
For runs lasting less than 70 minutes, aim for at least 25 grams of carbohydrates. For runs longer than 70 minutes, aim for 50-60 grams of carbohydrates. If you have less than 60 minutes before your run, opt for simple carbohydrates that are low in fat and fibre, such as bananas, toast, or graham crackers. If you have 1-2 hours before your run, you can include some fat and fibre in your pre-run snack, such as peanut butter on toast.
During the half marathon, aim for 25-30 grams of carbohydrates every 30 minutes at a minimum. For longer or higher-intensity efforts, you may need up to 90 grams of carbohydrates per hour. Spread out your fuel consumption every 20 to 30 minutes, and opt for fast, easy-to-digest sources of carbohydrates. Gels, chews, and drinks are popular choices for consuming carbohydrates during the race.
Fluids are crucial to avoid dehydration, which can lead to GI distress, muscle cramps, dizziness, and decreased performance. The average runner should aim for 8-16 ounces of fluid per hour, but this can vary depending on individual factors such as sweat rate. If you are a heavy sweater or running in hot and humid conditions, you will need to increase your fluid intake.
Electrolytes are also important to replace the sodium lost through sweating. The average runner should aim for 200-600 mg of sodium per hour, but this can vary depending on individual needs. You can add electrolytes to your water or slightly increase your salt intake before the race.

Pre-run nutrition and timing
In the 1 to 4 hours before your half marathon, the recommendation is 1 to 4 grams of carbohydrates per kg of body weight. For a 150-pound (68 kg) runner, that's 70 to 270 grams of carbs. Practice during training to figure out what timing and amount work best for your body. If you are eating over 2 hours before the start, consider adding a little protein, such as peanut butter on your bagel. However, if you are eating closer to the run, avoid too much fat and protein. Don't forget to drink enough fluid with your meal and consider having some electrolytes or making your own electrolyte drink.
Depending on the timing of your race, you may also want to take a snack to eat 60 minutes before getting to the start line or have a gel 15 minutes prior. For most runners, a half marathon falls into the ""long run over 80 minutes" category, so aim for 30-90 grams of carbohydrates per hour on the run. You can consume carbs on the run through a variety of options, including gels, chews, or drinks.
Remember, pre-run nutrition is highly individualised, and you may need to experiment to figure out what works best for you. The right nutrition plan is the one that works for you and doesn't give you an upset stomach. While some prefer gels, others go with chews or whole foods.

Mid-run fuel sources
There are various mid-run fuel options available, including gels, chews, and drinks. Gels are a popular choice, with some runners taking them at miles 5 and 10, or every 30 minutes. Others prefer chews, such as Skratch Energy Chews, which can be taken 5-10 minutes before the start and then every 20-30 minutes during the race. It is recommended to consume 25-30g of carbohydrates every 30 minutes, with some athletes benefiting from up to 50g carb/hour for endurance efforts over 2 hours. For longer or higher-intensity efforts, this can increase to 90g carb/hour.
Runners should also pay attention to hydration and ensure they are taking in adequate fluids and electrolytes. The average runner should aim for 8-16 oz of fluid per hour and 200-600 mg of sodium per hour, but this can vary depending on individual needs and sweat rate.
It is important to experiment with different fuel sources and find what works best for your body. Practicing your nutrition plan during training runs will help you dial in what works best for you and ensure you are optimally fueled for race day.

Post-run recovery
Rehydration
Rehydrating your body after a half-marathon is crucial. Your body loses a lot of fluids through sweating, especially in hot or humid conditions, so it's essential to replenish those fluids. Aim to drink about 16 to 20 ounces of water or an electrolyte beverage immediately after finishing the race. Sports drinks like Gatorade can also help with rehydration.
Nutrition
Nutrition is vital for post-run recovery. Your body has just undergone significant stress, and it needs the right nutrients to start the healing process. Consume calories, especially carbohydrates, to replace the glycogen stores you burned through during the race. Small, easily digestible snacks with carbohydrates and protein are ideal for jumpstarting recovery. Within a few hours, your stomach should be ready for a larger, nutritionally balanced meal. Carbohydrates will replenish your energy, protein will aid in muscle rebuilding, and healthy fats have overall health benefits.
Light Movement
Incorporating light movement after your run can aid in recovery. Consider a slow walk, some gentle yoga, or light stretching. This helps prevent blood from pooling in your lower extremities, which can cause a decrease in blood pressure and lead to dizziness or fainting. However, avoid intense physical activities immediately after the race, as your body needs time to heal and recover.
Rest and Recovery Timeline
Give yourself time to rest and recover after the half-marathon. You can follow a gradual recovery timeline, starting with a few days of no running, then slowly incorporating light running, and eventually building up to your regular running routine over several weeks. Listen to your body, as the recovery time varies depending on factors such as age, running experience, and race intensity.
Compression Gear
Consider using compression gear, such as compression socks or leggings, during your recovery. These can help prevent blood pooling and reduce the risk of lactic acid buildup and swelling.
Post-Race Celebrations
Completing a half-marathon is a significant accomplishment, so feel free to indulge in some celebratory meals or treats with your run buddies. However, it's best to avoid alcohol for at least 24 hours, as it can interfere with your body's recovery process.

Individual variation
The amount of fuel required for a half marathon varies from person to person. Each athlete is a unique individual who needs a specialised nutrition plan tailored to them. While all three macronutrients—carbohydrates, protein, and fat—are essential, carbohydrates take centre stage when it comes to fuelling for endurance running. They provide a quick, readily available source of energy for muscles and other vital organs.
The right nutrition plan is one that works for the individual and doesn't give them an upset stomach. While some prefer gels, others opt for chews or whole foods. Energy gels can sometimes lead to GI distress due to fructose, so it's important to try several different brands to see how the body reacts. It's also beneficial to consume simple carbohydrates that are low in fat and fibre, such as bananas, toast, cereal, or graham crackers, especially if there is less than an hour before the run. If there is more time before the run, it may be possible to include some fat and fibre in the pre-run snack, such as toast with peanut butter.
The amount of fuel also depends on factors such as the runner's pace, size, experience, and gastrointestinal tolerance of fuel sources. For instance, slower runners should fuel by time rather than mileage. Additionally, the weather conditions on race day may require adjustments in hydration and electrolytes. It's recommended to bring more fuel than anticipated to account for any changes in pace or weather conditions.
It's crucial to have a solid nutrition plan and to start fuelling during training. This involves experimenting with different fuelling strategies to determine what works best for the individual. While it's possible to complete a half marathon without additional fuel, it may compromise performance and increase the likelihood of struggling in the final miles due to depleted glycogen stores.
