Race day is the culmination of your dedication, training, and perseverance. To ensure all your hard work pays off, it's crucial to have a well-structured nutrition plan. Proper fueling not only enhances performance but also aids in recovery and overall well-being. Let's delve into a comprehensive guide to optimize your nutrition before, during, and after the race.
Pre-Race Nutrition: Building the Foundation
Reflecting on my own experiences, I've come to appreciate the significance of a well-thought-out pre-race nutrition strategy. In my early racing days, I underestimated the importance of carbohydrate loading, often focusing solely on the meal the night before.
This oversight led to energy deficits and unnecessary pains midway through all of my events. Through research and personal trials, I learned that effective carbohydrate loading is a multi-day process that allows muscles to maximize glycogen storage. This gradual approach not only boosts energy reserves but also minimizes any dreaded gastrointestinal discomfort on race day.
As with everything in nutrition, this process is unique to every individual. It is important to learn concepts and adapt them into a process that will work best for you. there. is no one-size-fits-all plan and the best strategy is the one that is adaptable to your unique body, preferences, and goals.
Let's Talk About Carbohydrate Supercompensation:
Supercompensation is a physiological process where the body adapts to stress (such as training or depletion) by overcompensating and restoring resources (like glycogen, strength, or endurance) to a level higher than before the stress occurred.
This results in improved performance and increased capacity to handle future stress. In the context of carbohydrate super-compensation (carb-loading), it refers to the strategy of depleting glycogen stores through training followed by a period of high carbohydrate intake to allow the muscles to store more glycogen than usual. This enhances endurance performance by delaying fatigue and maximizing energy availability on race day.
Supercompensation is commonly applied in:
✅ Endurance sports (marathon, triathlon) – maximizing glycogen storage for sustained performance.
✅ Strength training – allowing muscles to rebuild stronger after intense training.
✅ Tapering phases – reducing training load while maintaining high-quality nutrition to peak at the right time.
The super-compensation cycle typically includes:
1️⃣ Stress Phase: Intense training and depletion (e.g., glycogen depletion workouts).
2️⃣ Recovery Phase: Reduced training load with increased fueling.
3️⃣ Supercompensation Phase: The body adapts and stores more glycogen, strength, or endurance than before.
Supercompensation is a key principle in endurance sports, helping athletes time their peak performance for race day.
The process of super-compensation:
Early Week (7–4 days before race): Engage in high-intensity training sessions while maintaining decreasing carbohydrate intake. This combination depletes existing glycogen stores, priming your muscles for the super-compensation process.
Late Week (3–1 days before race): Reduce training intensity and simultaneously increase carbohydrate consumption to approximately 70% of your total caloric intake. This shift facilitates glycogen super-compensation, where muscles store more glycogen than usual, providing an extra energy reservoir for race day.
Timing of Carbohydrate Loading:
It's essential to understand that effective carbohydrate loading is not achieved by consuming large amounts of carbs the night before the race. Instead:
Gradual Increase: Begin increasing your carbohydrate intake several days prior to the event. This approach allows your body to adjust without causing gastrointestinal distress on race day.
Pre-Race Meal: On race morning, consume a light, easily digestible meal rich in carbohydrates to top off glycogen stores without overloading your digestive system. Most importantly, NOTHING NEW ON RACE DAY. Race day is not a time to try new foods, keep it to what you know and what you have trained with.
Food Choices and Gut Health:
To minimize the risk of digestive issues on race day:
Opt for Low-Fiber Carbohydrates: In the 2–3 days leading up to the race, choose low-residue carbs such as white rice, white bread, and pasta. These options reduce the residue in the gut, potentially preventing discomfort during the race.
Avoid High-Fiber Foods: Steer clear of high-fiber foods like brown rice, whole wheat bread, and raw vegetables during this period, as they can be harder to digest and may cause gastrointestinal issues.
During the Race: Sustaining Energy and Performance
During my initial races, I often relied on a single carbohydrate source, which sometimes led to energy crashes and stomach discomfort. Through experimentation, I discovered the benefits of combining both glucose and fructose into my nutrition plan.
This dual-source strategy leverages separate absorption pathways, allowing for increased carbohydrate intake without overwhelming the digestive system. This approach has been a game-changer, providing sustained energy and enhancing my overall race performance.
Carbohydrate Intake:
Maintaining energy levels during the race is crucial. For events lasting over two hours:
Consume 60–90 grams of carbohydrates per hour.
Understanding Carbohydrate Absorption:
The human body utilizes multiple pathways to absorb carbohydrates, primarily through glucose and fructose transporters. Here's a breakdown:
Glucose: Absorbed via the SGLT1 transporter in the small intestine. This pathway can become saturated when intake exceeds approximately 60 grams per hour.
Fructose: Utilizes a separate transporter known as GLUT5. By consuming fructose in addition to glucose, you can tap into this alternative pathway, allowing for greater total carbohydrate absorption.
Optimizing Intake:
By combining glucose and fructose in a 2:1 ratio (e.g., 60 grams of glucose and 30 grams of fructose per hour), athletes can achieve higher carbohydrate absorption rates, leading to improved endurance performance and reduced gastrointestinal discomfort.
Sources:
Energy gels or chews: Convenient and specifically formulated for rapid absorption.
Sports drinks: Provide both carbohydrates and essential electrolytes.
Bananas or dried fruits: Natural alternatives rich in carbohydrates and potassium.
2. Hydration and Electrolytes:
For endurance athletes, the Galpin Equation serves as a strong starting point for hydration but needs to be adapted for long training sessions, sweat loss, and race-day hydration strategies.
Galpin Equation = Daily Water Intake (Oz) = Body Weight (Lbs) x (.75 - 1.0)
0.75 x body weight (oz): For endurance athletes on rest days or in cooler climates.
1.0 x body weight (oz): For training days or moderate-intensity sessions.
+ 16-24 oz per hour of training: To replace sweat loss during workouts.
+ Extra based on sweat rate: If training in heat/humidity, additional intake is crucial.
Example for a 160 lb endurance athlete:
Daily Baseline: 160 x 0.75 to 1.0 = 120-160 oz per day.
Long Training Session (2 hours): Add 32-48 oz.
Total Needs: 150-200 oz per day depending on conditions.
Other Considerations for Endurance Athletes:
Electrolyte Balance: Water alone isn’t enough—consume electrolytes (sodium, potassium, magnesium) to prevent hyponatremia.
Sweat Rate Calculation: Weigh yourself before and after a run. Each pound lost = ~16 oz of fluid needed for replenishment.
Pre-Hydration: Aim for 16-20 oz of water 2-3 hours before a long run or race.
During Exercise: 4-8 oz every 15-20 minutes in races or long training runs.
This approach ensures consistent hydration, preventing dehydration-related fatigue, muscle cramps, and performance drops.
My Personalized Fuel Blend:
Many athletes find success with customized hydration solutions. A popular blend includes:
Medium-Chain Triglycerides (MCT) Oil: Provides a quick, easily digestible source of fats. MCTs are rapidly absorbed and can enhance endurance performance.
Electrolyte Mix: Replenishes essential minerals lost through sweat, maintaining muscle function and preventing cramps.
Carbohydrate Powder: Supplies a steady stream of glucose and fructose to sustain energy levels over long durations
Preparation Tips:
Mix these components in a blender and put them into a bottle to create a comprehensive fuel source that addresses energy, hydration, and electrolyte needs. Ensure you've tested this blend during training to confirm it agrees with your digestive system and meets your energy demands.
Make bottles ahead of time and store them in the freezer if you wish to save time and have your nutrition ready for the week!
Post-Race Nutrition: Recovery and Replenishment
I’ve seen firsthand how many endurance athletes completely neglect their post-race nutrition. They either celebrate with junk food (I get it—you just pushed your body to its limits, and you deserve something rewarding) or they don’t eat at all because their appetite is suppressed. But here’s the deal: how you refuel in the hours after your race will determine how well you recover and how soon you’re ready to train again. If you want to bounce back quickly, avoid injuries, and set yourself up for future success, you need a structured approach to post-race nutrition.
After a long race, your muscles are in a highly absorbent state, often referred to as the "anabolic window." This is when your body is primed to soak up nutrients and kickstart the repair process. If you skip this window or fill it with low-quality fuel, you’re leaving gains on the table and setting yourself up for unnecessary soreness and fatigue. The first 30 minutes post-race are golden—don't waste them.
Immediate Refueling (Within 30 Minutes): The Golden Window of Recovery
After your race, your body is depleted of glycogen, muscle fibers are damaged, and your hydration levels are likely imbalanced. To begin the recovery process immediately, aim for a 3:1 or 4:1 ratio of carbohydrates to protein. This ensures rapid glycogen replenishment while providing amino acids for muscle repair.
Here’s what I recommend for immediate post-race nutrition:
✅ Chocolate milk – The perfect recovery drink with the ideal carb-to-protein ratio.
✅ Protein smoothie with banana and oats – Easy to digest and packed with essential nutrients.
✅ A recovery shake with carbs + electrolytes + protein – A fast-digesting way to replenish lost nutrients.
✅ Greek yogurt with honey and granola – A tasty and effective recovery snack.
The key here is speed—get something in your system within the first 30 minutes post-race.
Even if you don’t feel hungry, drink your calories. You may not feel like eating right away, but your muscles are screaming for nutrients.
2. The 2-Hour Window: Follow-Up Meal for Continued Recovery
After your initial post-race fuel, it’s time to eat a real meal. Within 2 hours of finishing, aim for a meal rich in complex carbohydrates, lean proteins, and healthy fats. The goal here is to continue the recovery process while stabilizing blood sugar levels and replenishing lost nutrients.
Here are some post-race meal ideas:
🥩 Grilled chicken, roasted sweet potatoes, and sautéed greens – A balanced mix of lean protein, quality carbs, and micronutrients.
🍚 Rice bowl with salmon, avocado, and vegetables – Packed with omega-3s to reduce inflammation.
🥙 Whole grain wrap with turkey, hummus, and spinach – Provides sustained energy and muscle-repairing protein.
🍳 Egg scramble with whole grain toast and fruit – A great option if you prefer breakfast foods post-race.
💡 Pro Tip: Include anti-inflammatory foods like turmeric, ginger, and leafy greens to support muscle recovery and reduce soreness.
Rehydration: Restoring Fluid Balance and Electrolytes
Hydration doesn’t stop when you cross the finish line. For every pound of body weight lost during the race, drink approximately 20–24 ounces of fluid. If you’re craving salty foods post-race, that’s your body signaling for sodium replenishment.
Here’s how to effectively rehydrate:
💧 Drink electrolyte-enhanced fluids – Coconut water, electrolyte tablets, or a sports drink will do the job.
🍉 Snack on hydrating foods – Watermelon, oranges, and cucumbers help restore fluid balance.
🧂 Replenish sodium – If you’re experiencing muscle cramps, add a pinch of sea salt to your water or snack on salted almonds.
A Note on Alcohol: I get it, post-race beers are a thing. However, alcohol is a diuretic and can dehydrate you further and impair muscle recovery. If you choose to celebrate with a drink, balance it out by drinking extra water and getting in a recovery meal first. Your body will thank you the next day.
The Next 24–48 Hours: Long-Term Recovery Nutrition
Your recovery doesn’t end the night after the race. The 24–48 hours post-race are just as critical in ensuring you’re fully recovered and ready to get back to training.
Here’s what you need to do:
✅ Increase protein intake – Continue to aim for 1.2–2.0 grams per kg of body weight per day to repair muscle damage.
✅ Eat nutrient-dense meals – Focus on whole foods, quality carbs, and healthy fats.
✅ Stay on top of hydration – Even if you feel fine, continue drinking fluids consistently throughout the day.
✅ Prioritize sleep – This is when the majority of muscle repair occurs. Aim for at least 7–9 hours of quality sleep.
If you’re feeling excessive soreness or fatigue after 48 hours, you may need to increase your carbohydrate intake and ensure you’re eating enough overall calories to support full recovery.
My Take on Post-Race Nutrition
Post-race nutrition was something I neglected early on, and I paid the price for it. I used to think that training harder and running more would make me better, but the reality is your body only adapts when you give it the right tools to recover. Fueling properly post-race isn’t just about reducing soreness—it’s about getting stronger, faster, and more resilient for the next race.
I’ve personally found that having a post-race recovery plan makes a huge difference in how I feel the next day. Instead of waiting until I’m starving and eating whatever is in front of me, I now plan ahead by bringing a recovery shake and a pre-prepped meal for after the race. This way, I’m not left scrambling for food or making poor choices that slow down my recovery.
The biggest mistake I see athletes make is skipping post-race nutrition altogether because they don’t feel hungry or they’re too busy celebrating. Trust me—if you take your recovery nutrition seriously, you’ll notice a massive difference in how you perform long-term. It’s not just about one race; it’s about setting yourself up for sustained success.
Final Thoughts: Creating a Race Day Nutrition Strategy That Works for You
By now, you should see that nutrition isn’t just a race-day decision—it’s a week-long, even month-long strategy. How you eat leading up to, during, and after your race will determine how well you perform and recover.
Here’s what you should take away from this guide:
✅ Carb-loading starts days before the race, not the night before.
✅ Fueling properly during the race is non-negotiable—60–90g of carbs per hour for races over two hours.
✅ Post-race nutrition is just as important as pre-race—get in carbs, protein, and electrolytes ASAP.
✅ Hydration is an all-day effort, not just something to focus on during training.
✅ Having a plan is key—don’t leave your race day fueling to chance.
Endurance racing is about long-term growth, not just one race at a time. If you dial in your nutrition strategy, you’re setting yourself up for consistency, longevity, and PR after PR.
Train smart. Fuel right. Recover strong. 💪🏃♂️🔥
