러닝 영양 완벽 가이드

Running nutrition doesn't have to be complicated. Enough carbs, steady protein, and staying on top of fluids and electrolytes — those three things cover most of it. Because your needs shift a lot with distance, intensity, temperature, and your own body, treat everything below as a general guideline and remember that individual differences are real.

1. Fueling by Distance — General Guidelines

* The table above is a general recommendation and should be adjusted for your own pace, the temperature, and your body.

2. Carbohydrates — Your Main Running Fuel

• General recommendation — ACSM (American College of Sports Medicine) guidelines suggest a range of 3–10 g per kg of body weight per day, depending on training intensity. Casual runners sit toward the low end, while those in marathon training are usually in the mid-to-high range.
• Right before a run (1–2 hours out) — Easy-to-digest carbs like a banana, bread, or oatmeal are a safe bet.
• Carb-loading before a race — Its benefit is well documented for events lasting over 90 minutes. Raising your carb intake 1–3 days before the race is a common approach, but test it in training first to see how your stomach handles it.
• Post-run recovery — Studies suggest that taking in carbs and protein together within an hour of finishing supports recovery.

3. Protein — Recovery and Muscle Maintenance

Endurance athletes are known to need somewhat more protein than the average adult. A commonly cited range is 1.2–1.6 g per kg of body weight per day, though it varies with your training load, build, and eating habits.

• For absorption, spreading protein across 3–4 servings a day is generally preferred over loading it all into a single meal.
• Protein figures for foods are averages and vary by product and cut (e.g. 100 g of chicken breast ≈ roughly 20–25 g of protein).

4. Fluids and Electrolytes

The amount of water and sodium you lose through sweat during a run varies enormously with your body, the temperature, humidity, and intensity. One person may lose only 400 ml an hour, while another in hot conditions easily loses over a liter.

• Easy runs under an hour — Water alone is usually enough.
• Over an hour, or in hot weather — Consider an electrolyte (sports) drink.
• A quick dehydration check — Compare your weight before and after a run; if it dropped noticeably (a 2%-or-more threshold is often cited), rehydrate well before your next session.

5. Energy Gels — Support for Longer Runs

On runs longer than 90 minutes, your stored carbohydrate (glycogen) runs low, which is a common cause of slowing down in the later stages. Commercial energy gels typically list 20–30 g of carbs each, but this varies by product, so check the label.

• Try gels in training, never for the first time on race day — Stomach trouble is common. Start using the same product about four weeks out.
• Caffeinated gels — Some reports find them helpful late in a run, but if you don't usually consume much caffeine, watch out for jitters or nausea.

6. Caffeine

Research suggests caffeine before a run may aid endurance (with large individual variation). A modest dose 30–60 minutes before exercise is a commonly cited approach, but caffeine can affect sleep, heart rate, and digestion — so if you don't normally drink it, there's no need to add it on purpose.

7. Key Takeaways

1. "Regularly and with variety" matters more than "what and how much."
2. Never use a new supplement, gel, or drink for the first time on race day. Prove it out in training first.
3. Trust your body's signals most — fatigue, weight, sleep, digestion. Treat the numbers as reference only.
4. For special situations (illness, pregnancy, medication, or a diet involving large weight changes), always proceed only after consulting a professional.
