Fuel Perfect: Carb & Hydration Kundenservice

- Weather-aware, for YOUR venue. Enter where and when you're racing. Fuel Perfect pulls the forecast for that exact place and time - or, for races still far out, the typical conditions for that date - and adjusts your fluid and sodium for the heat.
- Every number is cited. Tap any recommendation to see the research or expert guidance behind it. No black box, no influencer hot takes — just transparent sports science you can check yourself.
- Works offline. The whole recommendation engine runs on your device. Only the weather lookup needs a connection.

YOUR PERSONAL PLAN

- Carbohydrate target from 30 up to 90–120 g/hr, scaled to your event length and capped by what your gut can actually handle - with built-in gut-training step-ups.
- Fluid target built from your sweat rate, body size, intensity, and the heat, with guardrails that warn you about both dehydration and over-drinking.
- Sodium target matched to your fluid intake and how salty a sweater you are.
- A clear timeline: exactly when to take each gel, chew, and sip.

REAL PRODUCTS AND DIY

- Map your plan onto real fuels - Maurten, SiS, GU, Precision, Tailwind, Skratch, Neversecond and more - and watch a running total stack up against your targets.
- Prefer to mix your own? Built-in maltodextrin-to-fructose drink-mix and bicarbonate calculators.

GO DEEPER (OPTIONAL)

- Caffeine and sodium-bicarbonate strategies, with clear dosing and safety notes.
- Log your sessions, rate how your gut felt, and watch your carb tolerance climb over the weeks.
- Export any plan as a clean one-page PDF - numbers, timeline, and shopping list.
