Running Nutrients 101: The Basics To Get You Moving


Do you want to set new personal records in your running but find yourself "hitting the wall" too often? The key lies in your nutrition. Nearly 36% of amateur athletes, including runners, don't even meet their most basic nutritional needs1.

As we'll explore in our next blog, the journey to optimal running performance doesn't stop at merely following outdated and generic nutrition guidelines. To truly excel, we need to delve deeper into personalising nutrition based on your physiology and genetics. But for now, let's explore the foundational nutrients that runners at all levels need to focus on for good performance and recovery.

In this blog we cover:

  1. Protein: Your Muscle's Best Friend
  2. Carbohydrates: The Quick Energy Provider
  3. Fats: The Long-Term Energy Supplier
  4. Fibre: The Digestive Aid
  5. Vitamins and Minerals: The Unsung Heroes
  6. Electrolytes: More Than Just Salt
  7. Water: The Essential Element

Let’s dive in!

Protein: Your Muscle's Best Friend

When you run, your muscles break down, entering a phase called catabolism. Post-run, they repair and strengthen in a phase called anabolism. Protein, made of essential and Branched-Chain Amino Acids (EAAs and BCAAs), is crucial for this repair process2.

If you are not consuming enough protein, expect to experience muscle weakness, longer recovery times, and increased susceptibility to injuries2.

👉 Recommended Sources: Chicken, peas, fish, eggs, turkey.

Carbohydrates: The Quick Energy Provider

Carbohydrates act as a primary fuel during your run. They are stored as glycogen in muscles and liver and are converted to glucose for quick energy3. Lack of sufficient carbs can result in fatigue and poor concentration3.

  1. Simple Carbs: Quick to digest; consume during or post intense runs.
  2. Complex Carbs: Slow-releasing; good for sustaining long runs.

👉 Recommended Sources: Whole grains for complex carbs; fruits and energy gels for simple carbs.

Fats: The Long-Term Energy Supplier

Fats provide sustainable energy, especially during longer, less intense runs4. Omega-3 fatty acids, in particular, are anti-inflammatory, aid in recovery, and help the body absorb fat-soluble vitamins, like A, D, E, and K5.

👉 Recommended Sources: Avocado, nuts, oily fish, olive oil.

Fibre: The Digestive Aid

Fibre aids digestion, regulates blood sugar, and has anti-inflammatory benefits6. However, too much before a run can be problematic – it’s all about timing and balance7.

👉 Recommended Sources: Fruits, vegetables, whole grains, legumes.

Vitamins and Minerals: The Unsung Heroes

Don't overlook micronutrients; they play essential roles in your running performance and recovery8. There are 26 essential vitamins and minerals. For runners, these 9 are key:

  • Iron: Essential for oxygen transport to muscles9.
  • Magnesium: Helps in muscle contraction and relaxation10.
  • Vitamin A: Aids in vision and immune function11.
  • Vitamin B9 (Folate): Helps in cell repair and muscle growth12.
  • Vitamin C: Boosts immune function13.
  • Vitamin D: Vital for bone health14.
  • Calcium: Supports bones and muscle function15.
  • Zinc: Aids in muscle repair and immune function16.
  • Selenium: Acts as an antioxidant17.

👉 Recommended Sources: Lean meats, leafy greens, whole grains, fruits.

Electrolytes: More Than Just Salt

Electrolytes like sodium, potassium, calcium, and magnesium are lost through sweat and need to be replenished18. During shorter runs or workouts, your regular diet should suffice. However, for long runs, especially those in hot and humid conditions, an electrolyte supplement can be beneficial18.

👉 Recommended Sources: Table salt, bananas, dairy products, leafy greens.

Water: The Essential Element

Finally, without adequate hydration, even the best training plans can fall apart. Water regulates body temperature, lubricates joints, and facilitates cellular metabolism19.

Your performance as a runner is not just a product of your training but also of your nutrition and hydration. By ensuring a balanced intake of proteins, carbs, fats, fibre, micronutrients, electrolytes, and water, you'll be setting yourself up for running success. Keep an eye out for our next blog, where we'll discuss how to take your nutrition to the next level by tailoring it to your specific physiology and genetic profile.
