For a 70 kg runner consuming 3,000 calories per day (average during hevy training), that translates torough 375-488 grams carbohydates (50- 65%), 112- 150 grams protein (15- 20%), and 67- 100 grams fat (20- 30%).

Putting It All Together: A Sample Day of Balanced Nutrition

Te following example is for a 70 kg runner on a 3- hour long run day with moderate intensity. Adjuss portion sizes to your body weight and activity level, and substitute foods based on your preferences and tolerances.

  • Breakfast (2- 3 godziny before run): Xi1; Xi1; FLT: 1 Xi3; Xi3; Oatmeal (80g oats) with 1 banana and2 tbsp almond butter + 250 mL milk (~ 50g carb, 18g protein, 20g fat)
  • Xi1; Xi1; FLT: 0 XI3; XI3; During run (per hour): XI1; XI1; FLT: 1 XI3; XI3; 2 energy gels (25g carbs each) + 500 mL sports drink (30g cars) = 80g carbs per hour. If running more than 3 hours, add a small compact of protein (e.g., one protein chew per hour) to tect tolerance.

Total (przybliżone): 305g karb, 155g protein, 95g fat, ~ 2,700 calories. This provides a solid foldation for recovery and d supports next day 's training. Adjuss based on your specific needs - if you feel hungry mid- afternoun, add another snack; if you' re trie ing to lose weigt, adjust portion sizes but keep protein high.

For variety, consider different combinations: a quinoa bowl wigh black beans and avocado for lunch, or a smer- fry with tofu andd brown rice for dinner. The key is consistent distribution of protein and carbs across all meals.
