1. Pre-Race Nutrition: Fuel Your Tank Strategically

A. 3–7 Days Before the Race: Carb Loading

• Goal: Maximize glycogen stores in muscles and liver (each gram of carb holds 3g water, so expect slight water weight gain).
• How to Do It:
  • Increase carbs to 6–10g/kg body weight daily (e.g., 400–600g for a 70kg athlete).
  • Focus on marathon nutrition staples like oatmeal, sweet potatoes, and quinoa—avoid high-fiber foods to prevent gut issues.

B. The Night Before: Timing Matters

• Dinner: Eat 3–4 hours pre-bed to allow digestion. Opt for easily digestible carbs (pasta, rice) + lean protein (grilled chicken, tofu) + minimal fat / 纤维 (no fried foods or raw veggies).
• Example: Spaghetti with turkey meatballs and a side of steamed spinach.

C. Race Morning: The Critical 2–3 Hours

• Pre-Race Meal: Eat 2–3 hours before start time to avoid running on a full stomach.
  • Carbs: 1–2g/kg body weight (e.g., 70–140g for 70kg: 2 slices of toast + banana + honey).
  • Avoid New Foods: Stick to tried-and-tested options to prevent stomach upsets.
• Hydration: Drink 500ml water/electrolyte drink 1 hour pre-race; add a pinch of salt for sodium.

2. Race Day Hydration: Balance Water and Electrolytes

A. During the Race: Sip Smartly

• Hydration Rate: 300–600ml/hour, adjusted for sweat loss (weigh yourself pre/post-run; drink 16oz for each pound lost).
• Electrolytes: Sodium (500–1,000mg/hour), potassium (200–300mg/hour) to prevent cramps and hyponatremia (low sodium).
• Drink Choice:
  • Short Races (10K–Half Marathon): Water + 1 gel/hour (20–30g carbs).
  • Long Races (Marathon/Triathlon): Sports drink (15–20g carbs/100ml) or gels + water, alternating every aid station.

B. Common Hydration Mistakes to Avoid

• Overhydration: Drinking too much water without sodium can lead to dangerous electrolyte imbalances.
• Underhydration: A 2% body weight loss from sweat reduces performance by 10%.

3. In-Race Nutrition: Fuel for Sustained Energy

A. Carb Intake by Race Distance

• 10K–Half Marathon (1–2.5 hours): 30–60g carbs/hour (1–2 gels, or 1 energy bar).
• Marathon (2.5–4 hours): 60–90g carbs/hour (3 gels + sports drink).
• Triathlon/Ironman (4+ hours): 90–120g carbs/hour (gels, energy chews, or real food like dates/bananas).

B. Timing Your Fuel

• First Gel: 30–45 minutes into the race, then every 45–60 minutes thereafter.
• Liquid vs. Solid Fuel: Use gels for convenience; solids (like a PB&J sandwich) for races over 3 hours, but practice chewing while moving.

C. Triathlon-Specific Tips

• Swim to Bike Transition: Have a gel ready immediately after exiting the water—digestion is harder on the bike, so start fueling early.
• Bike to Run Transition: Finish fueling 30 minutes before starting the run to avoid side stitches.

4. Post-Race Recovery: Repair and Replenish

A. The Golden Hour: Refuel Rapidly

• Carbs: 1.5g/kg body weight within 30 minutes (e.g., 105g for 70kg: chocolate milk + oatmeal cookies).
• Protein: 0.3–0.4g/kg body weight to kickstart muscle repair (e.g., 20–30g: Greek yogurt + whey protein).
• Hydration: Drink 500ml electrolyte-rich fluid (add salt to water if no sports drink available).

B. 2–4 Hours Post-Race: The Main Recovery Meal

• Focus on: Lean protein (salmon, eggs), complex carbs (quinoa, rice), and anti-inflammatory foods (berries, spinach).
• Example: Grilled chicken salad with quinoa, avocado, and a side of pineapple (natural anti-inflammatory).

C. 24–48 Hours Post-Race: Prioritize Rest and Nutrition

• Sleep 7–9 Hours: Critical for immune system recovery—use a heart rate monitor to track deep sleep stages.
• Continue Hydration: Aim for 3–4L water daily, with electrolytes if still sore.

5. Nutrition Strategies for Specific Events

A. Marathon Nutrition

• Avoid Fiber: Skip high-fiber foods 24 hours pre-race to prevent bathroom breaks mid-race.
• Practice Fueling: Do a “dress rehearsal” during your last long run to test gel/fluid tolerance.

B. Triathlon Tips

• Bike Leg Fueling: Use a bento box for easy access to gels/chews; practice opening packages while riding.
• Run Leg Hydration: Walk through aid stations to drink safely—spilling costs more time than a 10-second walk.

C. 10K/5K Races

• Pre-Race Meal: Eat 1–1.5 hours before—opt for simple carbs (a banana + honey) to avoid heavy digestion.
• In-Race Fuel: Only necessary for slower runners (over 1 hour); focus on hydration instead.

6. Common Nutrition Myths Debunked

1. “I need to load up on protein pre-race” – No, carbs are king for glycogen stores; protein is more important post-race.
2. “Drink as much as possible to avoid dehydration” – Overhydration is dangerous; drink to thirst and replace electrolytes.
3. “New foods won’t affect me on race day” – Always test nutrition in training to avoid gut issues.

Gear to Enhance Race Day Nutrition Planning

1. GPS Sports Watch

• Track Sweat Loss: Weigh yourself pre/post-training to calculate race-day hydration needs.
• Pace Alerts: Ensure you’re on schedule to hit nutrition/hydration checkpoints.

2. Hydration Pack/Vest

• Marathon/Triathlon: Use a 2L vest (e.g., Salomon Agile) for hands-free hydration during long races.

3. Portable Nutrition Kit

• Race Belt: Carry gels/chews in a stretchy belt (FlipBelt) for easy access without bouncing.
