🥗 Nutrition Basics for Endurance Athletes
Why Fueling Is the Fourth Discipline of Triathlon
In triathlon, nutrition is often called the fourth discipline — and for good reason. You can have the perfect training plan, the fastest bike, and the strongest engine, but without the right fueling strategy, performance falls apart long before the finish line. Nutrition is the thread that ties your swim, bike, and run together.
Whether you’re training for a 70.3, a full 140.6, or building toward your next long‑course season, mastering your fueling plan is essential. Below is a complete guide to help you fuel smarter, race stronger, and recover faster — featuring real products available at Playtri St. Petersburg.
🍽️ Daily Nutrition: Your Foundation
Carbohydrates: Your Primary Fuel
Carbs power your long sessions, intervals, and race‑day efforts. Aim for 50–60% of daily calories from carbs. Choose slow‑burn sources like oats, rice, potatoes, fruit, and whole grains. For long workouts, take in 30–60g of carbs per hour

- CARBS Fuel Energy Gels (25g, 50g, 50g caffeinated) — budget‑friendly, gut‑friendly carb options
- Skratch Labs Super High‑Carb Drink Mix (when in stock)
Protein: Repair & Recovery
Protein rebuilds muscle tissue and reduces soreness. Target 1.2–1.7g per kg of body weight. Include protein within 30–60 minutes post‑workout

Hydration: Your Secret Weapon
Hydration is often the difference between a strong session and a miserable one. Start workouts well‑hydrated. For sessions over an hour, include electrolytes. Aim for 400–800mg sodium per hour in hot conditions

📅 Race‑Week Fueling for Long‑Course Athletes
Carb Loading (2–3 Days Out) -- Increase carbs to 8–10g per kg of body weight to top off glycogen. Stick to familiar foods and reduce fiber slightly.
Hydration -- Add electrolytes daily and avoid over‑hydrating.
Race‑Week Meals -- Keep meals simple, predictable, and easy to digest.
