Shocking! The Secret Diet of Ultra-Marathon Runners Revealed - Here's How They Fuel Up!
Introduction
Over the years of coaching, the most common question I've encountered is how runners should scientifically fuel during races. I remember thinking the same way until I read "Anatomy for Runners" and "Born to Run," which truly opened my eyes to the secrets of energy management. Today, I'm going to share the dietary secrets of ultra-marathon runners, unveiling how they maintain their energy during long-distance races.
During one training session, I led a group of runners on a long-distance run. One runner suddenly hit the wall, experiencing severe leg muscle pain and was unable to continue. Later, I found out he had only eaten a banana and drank a bottle of water before the race. Let me tell you, many fall into this trap; diet is crucial for running.
This reminds me of a significant point from "Born to Run": "Running is human nature, but to run well, scientific nutrition is key." The book discusses how the Tarahumara people achieve incredible feats with simple diets, providing us with valuable insights.
Core Content
1. The Importance of Carbohydrates
Carbohydrates are the primary energy source for runners. According to exercise physiology, we should consume enough carbs before and during the race to maintain blood sugar levels, preventing fatigue and energy dips due to hypoglycemia.
Real-Life Example: In a marathon, I observed a runner suddenly pick up the pace at mile 18. He had been consistently taking energy gels and sports drinks. Data shows that when blood sugar levels are stable, runners can maintain better pace and heart rate.
Recommendations:

Start carb-loading a week before the race, increasing carbohydrate intake.
During the race, consume carbs every 45 minutes to an hour, using energy gels or sports drinks.
Opt for low GI (Glycemic Index) carbs like whole grain bread, oatmeal, etc., to avoid blood sugar spikes.

2. Protein Intake
Protein is vital for muscle repair and recovery. Many runners overlook this, leading to prolonged muscle soreness and slow recovery post-race.
Real-Life Example: One of my students suffered from muscle soreness for days after an ultra-marathon. After I advised him to increase protein intake before and after races, his recovery time significantly improved.
Recommendations:

Increase protein intake before and after races with lean meats, eggs, yogurt, etc.
During the race, choose energy bars or drinks containing protein.
Immediately after the race, consume protein to aid muscle repair.

3. Electrolyte Balance
Long-distance running leads to significant sweat loss, which can cause muscle cramps and dehydration due to electrolyte depletion.
Real-Life Example: In an ultra-marathon, I saw a runner cramp up at mile 25 because he only drank water without replenishing electrolytes.
Recommendations:

Supplement with electrolyte drinks or salt tablets every hour during the race.
Choose drinks containing sodium, potassium, magnesium, etc.
Post-race, replenish electrolytes to restore fluid balance.

4. The Role of Fats
Fats serve as a long-term energy source for endurance running. Adequate fat intake can help runners maintain energy in the later stages of a race.
Real-Life Example: One of my students completed an ultra-marathon by increasing his intake of healthy fats like nuts and olive oil in the days leading up to the race.
Recommendations:

Increase healthy fat intake in the days before the race, such as nuts, fish oil, olive oil, etc.
During the race, opt for energy bars or nuts containing fats.
Post-race, replenish fats to restore energy reserves.

Practical Guidance
Detailed Training Methods
Carb Loading:

Start a week before the race, increasing daily carb intake to 5-7 grams per pound of body weight.
The day before the race, reduce training volume and increase carb intake to 10 grams per pound.

Race Day Fueling:

Every 45 minutes to an hour, consume carbs using energy gels or sports drinks.
Supplement with electrolyte drinks or salt tablets every hour.
Choose energy bars or nuts containing protein and fats during the race.

Post-Race Recovery:

Immediately consume carbs and protein to aid muscle repair and recovery.
Replenish electrolytes to restore fluid balance.
Increase healthy fat intake to restore energy reserves.

Solutions to Common Problems
Hypoglycemia:

Regularly consume carbs during the race to prevent blood sugar drops.
Choose low GI carbs to avoid blood sugar fluctuations.

Muscle Soreness:

Increase protein intake before and after races to aid muscle repair.
Post-race, perform stretching and relaxation to help muscle recovery.

Dehydration and Electrolyte Imbalance:

Regularly supplement with electrolyte drinks or salt tablets during the race.
Post-race, replenish electrolytes to restore fluid balance.

Advanced Training Suggestions
Training Methods for Elite Athletes:

Implement a cyclical diet strategy, adjusting nutrition based on training cycles.
Pre-race carb loading to increase glycogen stores in muscles and liver.
Use scientific fueling strategies during the race, tailored to individual needs.

My Unique Training Philosophy:

Incorporate the natural and simple diet principles from "Born to Run."
Use data analysis to create personalized nutrition plans.
Encourage runners to experiment with different dietary strategies during training to find what works best for them.

New Training Methods to Try:

Try intermittent fasting to increase fat utilization.
Use a high-fat, low-carb diet strategy to meet the energy demands of long-distance running.

Future Development Suggestions:

Combine genetic testing to create personalized nutrition plans.
Utilize smart devices to monitor body status and adjust nutrition strategies.
Draw from cutting-edge theories in "Born to Run" to explore more scientific dietary methods.

Conclusion
As an experienced coach, I urge you to pay attention to the science of nutrition in your training and races. Carbohydrates, protein, electrolytes, and fats are all essential energy sources for runners. With a well-thought-out nutrition strategy, you can not only maintain your energy during races but also speed up recovery and reduce the risk of injury.
"Born to Run" has given me many insights into the importance of nutrition in running. I hope you can benefit from these insights and find your own dietary secrets. Remember, running is not just about leg movement; it's a whole-body commitment. Keep training, eat scientifically, and you'll definitely run farther and faster!
