General Macronutrient Guidelines

Fueling your workouts effectively is essential for achieving peak performance and speedy recovery, and our General Macronutrient Guidelines provide a clear roadmap for optimizing your nutrition during training. This guide breaks down the vital roles of carbohydrates, protein, and fats—explaining how each contributes to energy, muscle repair, and sustained performance. You'll discover tailored recommendations based on training intensity, such as the precise carbohydrate needs for moderate efforts versus high-volume workouts, the ideal protein intake for muscle recovery, and the best sources of healthy fats for long-lasting energy. Additionally, the guidelines emphasize the importance of timing nutrient intake around workouts and maintaining a calorie surplus to ensure your body has the fuel it needs for every session.

Key Nutritional Components for All Races

To fuel for optimal performance, it's essential to focus on a few key nutritional components that support energy, hydration, and recovery. Below are the primary building blocks of any race nutrition strategy:

Carbohydrates: The Primary Fuel Source

Carbs are your body’s primary energy source during endurance races. They are stored as glycogen in your muscles and liver, and provide the quick energy needed to sustain long-duration activity.

  • Sources: Carbohydrates can come from a variety of foods and products, such as:

    • Whole foods: Bananas, oatmeal, rice, potatoes, pasta.

    • Sports nutrition: Energy gels, chews, sports drinks, energy bars.

  • Timing: Carbohydrates should be consumed before, during, and after the race:

    • Before the race: Aim for a carb-rich meal 2-3 hours before starting, like oatmeal or toast with fruit.

    • During the race: Consume carbs every 30-45 minutes, depending on race duration.

    • After the race: Replenish glycogen stores with a post-race meal or shake containing carbs and protein.

Proteins: Key for Muscle Repair and Recovery

Protein plays a critical role in muscle repair and rebuilding after strenuous physical activity. It's essential for recovery, particularly after long races like marathons and triathlons.

  • Sources: Lean meats, eggs, fish, dairy, plant-based options like tofu, beans, and legumes.

  • Timing: While protein isn’t as essential for fueling during the race, it is crucial post-race to repair muscles:

    • Post-Race: Consume protein within 30-60 minutes of finishing to begin muscle repair. Aim for about 15-25 grams of protein.

Fats: Energy for Long-Duration Races

While carbohydrates are the go-to for immediate energy, fats serve as a secondary fuel source for longer races, especially once glycogen stores are depleted.

  • Sources: Healthy fats like avocados, nuts, seeds, olive oil, and fatty fish.

  • Timing: Fat is typically consumed in the days leading up to longer events (such as ultra-marathons or Ironman) to provide a slow-burning energy source. Avoid heavy fats on race day, as they can be hard to digest during intense activity.

Electrolytes: Essential for Hydration and Muscle Function

Electrolytes like sodium, potassium, magnesium, and calcium are lost through sweat during endurance events. Maintaining a proper electrolyte balance helps prevent cramps, dehydration, and fatigue.

  • Sources:

    • Electrolyte drinks: Sports drinks or electrolyte tablets.

    • Whole foods: Bananas (potassium), nuts (magnesium), and salty snacks (sodium).

  • Timing: Electrolyte consumption should be consistent throughout your race, particularly in hot conditions or over long durations:

    • Before the race: Hydrate with an electrolyte solution in the hours leading up to your event.

    • During the race: Consume electrolytes every 30-45 minutes, especially during hot or humid conditions.

    • After the race: Replenish electrolytes along with fluids after your race.

Hydration: Stay Ahead of Dehydration

Hydration is just as critical as nutrition for maintaining performance. Dehydration can lead to fatigue, cramps, and a significant drop in performance.

  • Sources: Water and electrolyte drinks are both essential. In longer races, a mix of both is key to maintaining fluid balance.

  • Timing: The goal is to stay hydrated before, during, and after the race:

    • Before the race: Drink at least 16-20 ounces of water or an electrolyte drink 2-3 hours before starting.

    • During the race: Consume 4-8 ounces every 20 minutes, adjusting for conditions (hotter weather requires more hydration).

    • After the race: Continue hydrating post-race, ensuring fluids and electrolytes are replenished.
