Most runners focus on pace. Smart runners focus on fuel.
Glycogen is your body’s primary energy source during a marathon — stored in your muscles and liver, it’s what keeps you moving when the miles start to bite. But here’s the truth: it’s limited.
Run too hard, fuel too late, or get it wrong… and you hit the wall.
Get it right, and everything changes:
• Stronger, more consistent pacing
• Delayed fatigue
• Sharper focus
• Better performance when it matters most
The facts don’t lie:
Your body can typically absorb around 60–90g of carbs per hour during endurance exercise. Start early, stay consistent, and combine fluids + sodium to maximise absorption.
This isn’t guesswork. This is strategy. Fuel properly, and you don’t just survive the marathon… you perform in it.
Train smart. Race strong. Recover fully.
