Fueling Before Competition

Why PreCompetition Nutrition Matters

What you eat in the 2448 hours before an event sets the stage for how your body will perform. Carbohydrates fill the muscle glycogen stores that power intense effort, protein supports muscle repair, and fluids ensure blood volume and thermoregulation are optimal. Even small tweakssuch as timing a snack or choosing lowfiber foodscan prevent gastrointestinal discomfort that would otherwise derail even the most prepared athlete.

Key Nutrition Goals

• Maximise glycogen stores 710g of carbohydrate per kilogram of body weight over the 48hours leading up to the event.
• Maintain hydration Aim for 3545ml of fluid per kilogram daily, adjusting for sweat rate.
• Preserve muscle protein Include 1.21.6g of protein per kilogram each day.
• Limit gut distress Choose lowfiber, lowfat foods in the final 12hour window.

Nutrition Timeline

4824 Hours Before Competition

Focus on carbloading without overeating. Meals should be balanced, but carbohydrate intake should dominate. Suitable foods include:

• Wholegrain pasta, rice, quinoa
• Potatoes, sweet potatoes
• Fruitbased smoothies
• Lowfat dairy or plantbased alternatives

Keep protein moderate (2025% of calories) and keep fat to 30% of total energy to aid digestion.

124 Hours Before Competition

This window is about finetuning blood glucose and avoiding heavy meals that could sit in the stomach. Recommended foods are:

• Oatmeal with banana and a drizzle of honey
• Rice cakes topped with peanut butter and jam
• Lowfat yogurt with berries
• Plain toast with a small amount of jam

Fluid intake should be steady: sip 200300ml of a carbohydrateelectrolyte drink every 1520minutes.

21 Hours Before Competition

Goal: a small, easily digestible carb snack that raises blood sugar without causing a crash.

• One medium banana
• 30g of a sports gel or chew
• Half a slice of white bread with a thin spread of jam

Continue sipping a lowconcentration electrolyte drink (46% carbs) if youre prone to early dehydration.

During Competition

If the event lasts longer than 60minutes, replace 3060g of carbs per hour using gels, chews, or sports drinks. For ultraendurance events, consider easytoeat solids such as pretzels or rice balls.

Sample Meal Plan

Day 2 (48h before)

Breakfast: Large bowl of cooked oatmeal with raisins, a sliced apple, and a scoop of whey protein.

Lunch: Grilled chicken breast, 2cups of cooked white rice, roasted carrots, and a side salad with a lemonvinaigrette.

Dinner: Spaghetti with tomatobasil sauce, a generous serving of meatballs, and a small piece of fruit.

Snacks: Greek yogurt with honey, a handful of pretzels, and a sports drink.

Day 1 (24h before)

Breakfast: Pancakes topped with maple syrup and a side of banana slices.

Lunch: Turkey sandwich on white bread, sweet potato fries, and a fruit smoothie.

Dinner: Baked salmon, quinoa, steamed broccoli, and a cup of orange juice.

Evening Snack: Lowfat chocolate milk and a small handful of raisins.

Day of Competition

~3hours before: Oatmeal with a spoonful of jam, a banana, and 500ml of a dilute sports drink.

~1hour before: One rice cake with a thin spread of honey and 200ml of water.

During (if needed): One gel every 45minutes plus sips of electrolyte drink.

Common Mistakes to Avoid

• Skipping the carbload: Arriving with depleted glycogen greatly reduces endurance capacity.
• Eating highfiber or highfat foods too close to start: Increases risk of cramping and nausea.
• Relying solely on water: Without electrolytes, you may experience hyponatremia or early fatigue.
• Trying new foods on competition day: Unfamiliar ingredients are a leading cause of gastrointestinal upset.

Personalising the Plan

Everyones digestive system, sweat rate and metabolic needs differ. Use a training log to record:

• What you ate and when
• How you felt during the workout (energy, stomach comfort)
• Hydration status (weight change, urine colour)

Adjust carbohydrate ratios, fluid volume, and timing based on those observations. Athletes with higher body mass or those competing in hot climates may need 1015% more fluid and a slightly higher carb intake.

Conclusion

Effective precompetition fueling is a blend of science and personal experimentation. By loading glycogen, staying hydrated, and timing easytodigest carbs, you give your body the fuel it needs to perform at its best. The effort you put into planning the meals and drinks before the start line pays off in steadier energy, sharper focus and a reduced chance of gut problemskey ingredients for a successful competition.
