How to Fuel a Marathon: Complete Race-Day Nutrition Guide
Proper fuelling is one of the most important factors in marathon performance. Even with perfect training, poor fuelling can lead to fatigue, reduced pace, and hitting the wall.
Your body stores a limited amount of carbohydrate as glycogen, which becomes depleted during long endurance efforts. A structured fuelling strategy using Energy Pastilles for Marathon Running and a Carbohydrate Drink Mix for Endurance Performance helps maintain energy levels and sustain performance throughout the race.
Fuelling correctly allows you to maintain pace, delay fatigue, and perform at your full potential.
Why marathon fuelling matters
Carbohydrates are the primary fuel source during marathon running. Glycogen stores typically last 90–120 minutes, after which fatigue begins unless carbohydrates are consumed.
Without proper fuelling, runners experience:
• Sudden fatigue
• Loss of pace
• Increased effort
• Reduced performance
Consuming carbohydrates regularly using Energy Pastilles for Marathon Running helps maintain stable energy levels.
How many carbs per hour during a marathon
Recommended carbohydrate intake:
• Beginner runners: 30–60g carbs per hour
• Intermediate runners: 60g carbs per hour
• Advanced runners: 60–90g carbs per hour
Maintaining consistent intake using a Carbohydrate Drink Mix for Endurance Performance and Energy Pastilles for Marathon Running helps sustain endurance.
Consistent fuelling improves performance and reduces fatigue.
When to fuel during a marathon
Start fuelling early to prevent glycogen depletion.
Recommended strategy:
• Begin fuelling 30–45 minutes into the race
• Continue fuelling every 15–20 minutes
• Maintain consistent carbohydrate intake
Many runners use Energy Pastilles for Marathon Running because they allow consistent fuelling without relying on gels.
Pre-marathon fuelling strategy
24–48 hours before race day:
Increase carbohydrate intake to maximise glycogen stores.
Use a Carbohydrate Drink Mix for Endurance Performance to increase carbohydrate intake efficiently.
Eat a carbohydrate-rich meal 2–3 hours before the race.
Avoid unfamiliar foods on race day.
Example marathon fuelling plan
Before race
Consume carbohydrate-rich breakfast.
During race
Consume 60–90g carbs per hour using Energy Pastilles for Marathon Running and a Carbohydrate Drink Mix for Endurance Performance.
Fuel every 15–20 minutes.
After race
Consume carbohydrates to replenish glycogen stores and support recovery.
Hydration during a marathon
Proper hydration supports endurance performance.
Recommended fluid intake:
• 400–800ml per hour depending on conditions
Using a Carbohydrate Drink Mix for Endurance Performance helps maintain hydration and energy levels.
Common marathon fuelling mistakes
Avoid these common errors:
• Starting fuelling too late
• Consuming too few carbohydrates
• Inconsistent fuelling
• Relying on water alone
Using reliable fuelling options like Energy Pastilles for Marathon Running helps maintain consistent energy intake.
