02 · THE PROBLEM
Most endurance products are underdosed or ruin your gut.
You fuel up, and somewhere around hour two the cheap maltodextrin hits your gut and the wheels come off. GI distress hits up to 1 in 3 endurance athletes. Usually it's the fuel, not you.
- Sugary sports drinks with a sprinkle of sodium
- Maltodextrin that spikes blood sugars and causes gut issues
- Guessing how much to take, and getting it wrong on race day
03 · WHY IT WORKS
Clean carbs, engineered to sit well.
HBCD (highly branched cyclic dextrin) leaves the stomach fast and absorbs steadily, giving you sustained energy without the bloat or bonk of cheap maltodextrin. Every dose is named on the label.
HBCD carbohydrate
A low-osmolality carb that empties fast and sits light, with no gut issues.
Betaine Nitrate + Pink Salt

Monk fruit, fully labelled
No maltodextrin, no artificial sweeteners. Every dose shown.
04 · YOUR PLAN
Stop guessing. Get your exact numbers.
Endurance Fuel is the base of your plan. Enter your details and we'll show how many serves cover your sodium, then exactly what to add to hit your carbs.
Session intensity
Pre-fueling is usually adequate for this session
For sessions under 70 minutes, focus on arriving well fuelled and hydrated. A serve of Endurance Fuel 30 to 45 minutes before you start is all most athletes need.

If using gels, choose low-osmolality options and trial them in training. Never try something new on race day.
Serves are calculated to meet your sodium target first (6 to 12mg/kg/hr by intensity). Remaining carbs are filled from food to avoid over-loading sodium. Carb targets 0.5 to 1.1g/kg/hr. A guide only, so adjust to your gut in training.
05 · BUT WHAT ABOUT…
The honest answers.
"Only 20g carbs, isn't that low?"
On purpose. Endurance Fuel is the clean base that nails your sodium. The calculator scales serves to you, then you top up carbs from food or gels. You control the dose, with no fixed sugar-bomb.
"Will it wreck my gut like other fuels?"
HBCD is low-osmolality and empties the stomach fast, the opposite of maltodextrin. No artificial sweeteners or preservatives.
"Is it worth $79.90?"
Clean ingredients. Performance dosed. No gut issues. No nasties. Cheap products will compromise on all of these.
