How many gummies does your run actually need?
Enter your distance and expected finish time and we'll work out roughly how many Enduro Gummies to pack, based on general endurance carb-intake guidance - plus how that translates to caffeine, so you can dose it your way.

Pouch to pack
That's roughly one gummy every 15 minutes across your 4.0-hour effort - split it into full or training serves however suits your gut, since Enduro Gummy doses one gummy at a time, not a fixed packet.
Capped at 16 gummies - FSANZ caffeine limit
Your 50% target works out to more caffeine than FSANZ's 400mg/day guidance allows, so we've capped this recommendation at 16 Enduro Gummies (exactly 400mg caffeine) - this is a hard stop, not a suggestion. The remaining ~73 gummies' worth of carbs is best covered by our caffeine-free Enduro Gummy - Non-Stim, or by other fuel/water. Join the waitlist for it further down this page.
What's a training serve?
A training serve is just 3 gummies - half a full serve, so half the carbs (~12.5g) and half the caffeine (~75mg), for a fraction of the cost ($2.16). Because Enduro Gummy doses one gummy at a time rather than a fixed gel packet, you can dial fuelling up or down for whatever the session calls for:
- • Easier training runs where you don't want race-day caffeine
- • Long runs where you're easing your gut into fuelling before race day
- • Afternoon or evening sessions where a full caffeine hit isn't ideal
- • Stretching one pouch across more sessions

This calculator gives a general, rough estimate based on bodyweight and distance (not a lab-measured energy cost) - it isn't personalised advice. Everyone's gut, sweat rate, running economy, and caffeine tolerance differ; trial your fuelling plan in training before race day, and talk to a sports dietitian for individual guidance on longer events. The 16-gummy cap reflects FSANZ's general 400mg/day caffeine guidance for healthy adults and is not a substitute for individual medical advice.
