Nutrition Planning for Ultramarathon Runners: Pre-Race, During-Race, and Post-Race Strategies!
Introduction
Over the years of coaching, one of the most common questions I've encountered is about nutrition planning for ultramarathon runners. I recall an instance when I was leading a team for an ultra-marathon, and one of the athletes asked, "Coach, what should I eat?" At that moment, a quote from "Born to Run" flashed through my mind: "The food we eat is our fuel." This reminded me that nutrition planning isn't just about what to eat, but how to scientifically fuel the body for optimal performance.
Nutrition planning for ultramarathon runners is both complex and crucial. Many athletes stumble here. Eating too much before the race can lead to stomach discomfort; failing to replenish during the race can result in energy depletion; and improper recovery post-race can affect future training. Honestly, neglecting this aspect can easily lead to trouble during the race.
I often tell my athletes that nutrition planning is like updating the software for running; it determines whether you can perform at your best during the race. Today, I'll share detailed insights on nutrition planning for ultramarathon runners, combining my years of training experience with theories from "Anatomy for Runners."
Core Content
Pre-Race Nutrition Planning
1. Carbohydrate Loading
I used to think like everyone else until I read "Anatomy for Runners"... The book highlights that carbohydrates are the primary energy source for running. In the week leading up to the race, I recommend athletes increase their carbohydrate intake to ensure sufficient glycogen stores in muscles and liver. Data shows that pace and heart rate are related... and ample glycogen reserves help maintain a steady pace.
Case Study: Once, I had my team carb-load for a week before a 62-mile ultra-marathon, consuming 6-10 grams of carbs per pound of body weight daily. They performed exceptionally well, showing no signs of significant fatigue.
Recommendation: In the week before the race, consume 6-10 grams of carbs per pound of body weight daily. Opt for low GI (Glycemic Index) foods like whole grain bread, brown rice, and oatmeal, avoiding high-sugar, high-fat foods.
2. Hydration and Electrolyte Balance
Based on exercise physiology principles, we should... maintain hydration and electrolyte balance before the race. I advise athletes to drink plenty of water 24 hours before the race, ensuring urine is a pale yellow color. Also, supplement with electrolytes like sodium, potassium, and magnesium to prevent dehydration and muscle cramps.
Case Study: One of my students once neglected hydration before a race, leading to severe dehydration symptoms during the event, significantly impacting their performance.
Recommendation: Drink 8-12 ounces of water per hour in the 24 hours before the race, and 2 hours before, consume electrolyte drinks or sodium-rich foods like bananas or salt water.
During-Race Nutrition Planning
1. Energy Intake
Continuous energy supply is vital during an ultra-marathon. According to exercise physiology, we should... consume 30-60 grams of carbohydrates per hour to maintain blood sugar levels and muscle glycogen.
Case Study: A student of mine once failed to replenish energy timely during a race, leading to noticeable fatigue in the latter stages, affecting their final time.
Recommendation: Consume 30-60 grams of carbohydrates per hour. Choose energy gels, bars, or bananas, avoiding high-fat and high-protein foods.
2. Hydration and Electrolyte Intake
Hydration and electrolyte replenishment are equally important during the race. Data shows that pace and heart rate are related... and dehydration can increase heart rate, affecting pace. According to exercise physiology, we should... drink 8-16 ounces of water per hour and supplement electrolytes.
Case Study: One of my students didn't replenish electrolytes during a race, resulting in muscle cramps in the latter half, impacting their performance.
Recommendation: Drink 8-16 ounces of water per hour, and supplement with electrolyte drinks or sodium-rich foods like salt water or bananas.
Post-Race Nutrition Planning
1. Recovery Nutrition
Post-race nutrition is just as important. According to exercise physiology, we should... consume carbohydrates and protein within 30 minutes post-race to aid muscle recovery and glycogen resynthesis.
Case Study: A student once didn't replenish nutrients immediately after a race, leading to severe muscle soreness the next day, affecting training.
Recommendation: Within 30 minutes post-race, consume 1.2-1.5 grams of carbs per pound of body weight and 0.3-0.5 grams of protein per pound. Options include chocolate milk, bananas, or eggs.
2. Hydration and Electrolyte Intake
Post-race hydration and electrolyte replenishment are crucial. According to exercise physiology, we should... continue to hydrate and replenish electrolytes to prevent dehydration and muscle cramps.
Case Study: One of my students neglected hydration post-race, resulting in severe dehydration symptoms the next day.
Recommendation: Drink 8-12 ounces of water per hour post-race, and supplement with electrolyte drinks or sodium-rich foods like salt water or bananas.
Practical Guidance
Detailed Training Methods
1. Carbohydrate Loading in the Week Before the Race

Day 1: Normal diet, increase carb intake.
Day 2: Increase carb intake, reduce training volume.
Day 3: Continue increasing carb intake, light training.
Day 4: Peak carb intake, recovery training.
Day 5: Maintain high carb intake, light training.
Day 6: Slightly decrease carb intake, light training.
Day 7 (Day Before Race): Moderate carb intake, light training or rest.

2. Energy Intake During the Race

Per Hour: Consume 30-60 grams of carbs, choose easily digestible foods.
Per Hour: Drink 8-16 ounces of water, supplement electrolytes.

3. Post-Race Recovery

Within 30 Minutes: Consume 1.2-1.5 grams of carbs per pound and 0.3-0.5 grams of protein per pound.
Per Hour: Drink 8-12 ounces of water, supplement electrolytes.

Solutions to Common Problems
1. Stomach Discomfort

Recommendation: Choose easily digestible foods, avoid high-fat and high-fiber foods, and do trial runs with your race-day nutrition.

2. Energy Depletion

Recommendation: Supplement 30-60 grams of carbs per hour during the race, avoid long periods without energy intake.

3. Muscle Cramps

Recommendation: Supplement electrolytes during and after the race, avoid long periods without electrolyte intake.

Advanced Training Suggestions
1. Training Methods for Elite Athletes

High-Intensity Interval Training: Incorporate high-intensity intervals to improve the body's adaptation to high carbohydrate intake.
