Ironman nutrition is the key to finishing strong on race day. What to eat during an IRONMAN 140.6 or IRONMAN 70.3 triathlon? We will go over everything you need to know.
Burning Fat is Key In Ironman Nutrition
During half-ironman training, your heart rate will increase to five times the average rate for the day. The key to steady energy is to train your body to burn fat. As a primary fuel source as a fat-adapted athlete have a performance edge. Athletes with the best race times are great at burning fat.
Being dependent on carbs requires an athlete Despite burning so many calories in a single event, it is difficult for runners to eat or drink enough. You risk the dreaded bonk if your body is not good at fat burning.
Triathlon Nutrition Study
The FASTER Study showed that keto-adapted/fat-adapted athletes burned fat 2.3-fold over sugar-burning athletes.
The study has shown us that even the leanest athletes carry enough energy to complete the race.
Success with Ironman Nutrition
Ironman Nutrition may be no nutrition at all. Dr. Keith Runyan, a Type I diabetic, ran a full marathon without taking in any nutrition. He was able to maintain level blood glucose levels throughout the event.

How long does it take to train for an Ironman?
It takes anywhere from 24-36 weeks to train for an Ironman. During that training phase, you must train your body to burn fat.
To be ready on race day – train your body to burn fat, then add strategic carbs as a performance enhancement.
Train your body to burn fat?
During your base training phase, decreasing carbs and increasing fat and protein is essential. Avoid liquid calories during this time.
The goal at this time is to get to the point where you can do a 2+ hour workout with only water and electrolytes in Zone 2 and feel fine.
How do I get my food right? You have to consider two different factors – fat metabolism and triathlon physiology.
Fat Metabolism
If you feel weak or faint during the 2-hour training session, stick with the ketogenic diet to increase fat oxidation rates.
Training physiology
Lower your training intensity to Maximum Aerobic Function (MAF) Heart Rate Training. Depending on your level of insulin resistance.
Following a low-carbohydrate diet can take anywhere from 2 weeks to 16 weeks.
Producing ATP
The contraction of a muscle happens because your body produces ATP.
IRONMAN Race Day Nutrition Plan
Making an individualized calorie diet plan when racing for the Ironman. This might be an expensive task, but it is certainly worth it. It doesn’t mean a lot to remember it.
This chart will help you determine if you should consume a minimum of a kilogram of calories before training. During your training session, you will also be notified of your carbohydrate, fluid, and sodium intake, which will help maintain energy, hydration, and electrolytes throughout your training cycle. Most of our work is metrical. Please consult the calculator.
What should I eat on an Ironman run?
During an Ironman run, consuming foods that provide you with a sustained energy source and electrolytes to help you maintain your performance is essential. Here are some food suggestions to consider:
- Energy gels or chews: These are convenient and easy-to-digest sources of carbohydrates, which provide quick energy. They usually contain electrolytes like sodium and potassium that can help replenish lost minerals.
- Sports drinks: Sports drinks are also a great source of electrolytes and carbohydrates. Look for brands that contain a balanced sodium, potassium, and carbohydrate mix.
- Bananas: Bananas are an excellent source of carbohydrates, potassium, and other essential nutrients that can help fuel your run and prevent muscle cramps.
- Energy bars: Energy bars are also a convenient source of carbohydrates and protein, which can help keep you feeling full and energized during your run.
- Nut butter packets: Nut butter packets like almond or peanut butter are an excellent source of protein and healthy fats, which can help keep you feeling full and energized during your run.
Remember to experiment with different foods during training to find what works best. Nothing new on race day, and stay hydrated by drinking water and electrolyte-rich beverages.
Do you eat during an Ironman race?
It depends on your goals. If you don’t have a time goal, you don’t need to add a single carbohydrate or fuel on race day. Consider adding electrolytes depending on the heat and your body.
If you are trying to get on the podium, obtain a personal best, or qualify for the National Championships, you want to use carbohydrates.
Find your ideal fat-carb balance during an ironman. Your carbohydrate intake should be dictated by your body weight, body composition, and desire to lose or maintain weight.
Rule #1 for endurance athletes – Nothing new on race day. Every fuel you plan to use during the race should be tested during the Build Phase of training.
What do triathletes eat during the race?
There are endless combinations of fuels that you can use for race day. The choices are fats, proteins, carbohydrates, and minerals (electrolytes).
The process of testing out what works for you requires some tinkering.
How much should I eat in an Ironman?
For a recreational athlete, you don’t need to consume any fuel. For a competitive athlete, you may consume 50-300 calories per hour during their race.
During training, you must practice your nutrition plan to know what works best for you on race day.
Water is a byproduct of burning fat. This will give a fat-adapted endurance athlete a competitive edge. Practice your hydration strategy before race day.
As many athletes DNF from hyponatremia as they do from dehydration.
One thing is for sure, don’t assume what works for someone else will work for you.
What are high-carb foods during an Ironman?
If you are good at burning fat, you don’t need to worry about carrying excessive amounts of What is a good Ironman breakfast?
A good Ironman breakfast should be high in protein and some fat. This starts the body burning fat before you start the event.
How many calories do triathletes burn in a day?
The number of calories burned in a day by triathletes varies depending on how much they train, their age, and their size.
Generally, a triathlete may burn between 2,000 and 4,000 calories per day during intense training. During a race, the number of calories burned can be even higher.
Your body makes its own fuel through fat oxidation, and you can consume exogenous energy. Don’t worry about consuming all the calories you burned during the race.
What foods should triathletes avoid?
Triathletes should generally avoid fuels that cause gastrointestinal distress. Spicy food or too much fat can lead to disaster pants in training sessions or races.
Will the triathlon get me in shape?
Yes, a triathlon is an excellent way to get in shape. The combination of running, swimming, and cycling provides a full-body workout that can help you increase your endurance and strength levels.
Additionally, regular training for a triathlon can improve your aerobic capacity by increasing the amount of oxygen your body can use during exercise. With a healthy diet and regular training, a triathlon can be an effective way to get in shape.
In conclusion – fueling for endurance athletes
We are all different. It takes fuel and nutrition to run our bodies. Each person, depending on their genetics, age, sex, size, and training levels, they have different food and calorie requirements.
As an endurance athlete, prioritize fats and protein over carbohydrates to ensure you are fit, strong, and healthy.
Carbohydrates can make you faster, but they should be deemed a performance enhancement, not the foundation of solid nutrition.
