Tips for Special Considerations
Every race, every athlete, and every condition is unique. Consider these additional tips based on different factors that may impact your nutrition and performance.
Heat and Humidity
​Races in hot and humid conditions require special attention to hydration and electrolyte balance.
-
Adjust hydration: Drink more frequently and consider adding extra electrolytes to prevent cramping and dehydration.
-
Wear light clothing: Lighter clothing helps prevent overheating, allowing your body to cool more efficiently.
-
Consider cooling aids: Carry a cooling towel or use ice stations on the course to help lower your body temperature.
Dietary Restrictions
If you follow a special diet (e.g., vegan, gluten-free), it’s important to plan your nutrition to ensure you're meeting your energy needs.
-
Vegan/Vegetarian: Look for plant-based gels, bars, and recovery products that offer both carbs and protein.
-
Gluten-free: Many energy products are now gluten-free, but always check the labels to ensure they meet your dietary needs.
-
Allergies: Be cautious of hidden ingredients in energy products, and plan accordingly.
Training vs. Race Day Nutrition
Nutrition during training helps fine-tune your race-day plan. Experiment with different foods and timing during your long runs or rides to see what works best for your body.

Common Pitfalls and How to Avoid Them
Every race, every athlete, and every condition is unique. Consider these additional tips based on different factors that may impact your nutrition and performance.
Dehydration
Dehydration can lead to fatigue, cramping, dizziness, and even heat stroke. It occurs when fluid loss exceeds fluid intake, often in hot or humid conditions.
-
How to avoid it:
-
Pre-race hydration: Start the race well-hydrated by drinking water or electrolyte drinks in the hours leading up to the event.
-
During the race: Drink consistently, about 4-8 ounces every 20 minutes. Be mindful of your sweat rate and adjust your intake accordingly.
-
Post-race hydration: Continue drinking fluids after the race to restore balance and consider an electrolyte solution.
-
Hyponatremia (Low Sodium Levels)
Hyponatremia occurs when you drink too much water without sufficient electrolytes, diluting the sodium in your blood. This condition can lead to confusion, nausea, and in extreme cases, coma.
-
How to avoid it:
-
Balance hydration: Avoid overconsuming plain water. Use electrolyte drinks during long races to maintain sodium levels.
-
Consume electrolytes: Use electrolyte tablets, sports drinks, or salty snacks as part of your hydration strategy.
-
Over-fueling and Gastrointestinal (GI) Distress
Many athletes experience GI distress during races due to over-consuming foods or liquids that their stomachs aren’t accustomed to. This can result in nausea, cramping, and bloating.
-
How to avoid it:
-
Practice fueling: Train with the same nutritional products (gels, drinks, bars) that you plan to use on race day. This helps your digestive system adapt.
-
Moderate fueling: Don’t overeat or drink too much at once—small, frequent intakes are better than large amounts.
-
Under-fueling and Bonking
Bonking occurs when glycogen stores are depleted, leading to sudden fatigue, dizziness, and weakness. It’s most common in long-distance races when fueling is neglected.
-
How to avoid it:
-
Regular fueling: Eat every 30-45 minutes during long races, especially if your race lasts over 90 minutes. Use energy gels, sports drinks, or other quick-carb sources.
-
Stay ahead of the curve: Don't wait until you feel depleted to start fueling. Make fueling a consistent part of your race strategy.
