AI Race Fuel Prompt Generator
Gel prices and availability change constantly — a static list would be stale in a month. Instead, answer a short questionnaire and get a structured prompt for your AI assistant, built to search current prices in your country and rank everything by cost per gram of carbohydrate.
1 · What do you want your AI to do?
2 · About you and your event
3 · Your prompt — copy it into Claude, ChatGPT or any AI assistant

I want: - A shortlist of 5–10 products available to me, with where to buy each one - The cheapest reliable way to hit my carbohydrate target per hour - At least one high-carb option and at least one gentle-stomach option - Caffeine-free options only My profile: - Sport / event: Marathon (~240 min expected) - Bodyweight: 70 kg - Target carbohydrate intake: 60 g/hour - Sweat level: medium (sodium target ~650 mg/hour) - Sensitive stomach: no known issues - Caffeine: I avoid caffeine — caffeine-free options only - Country: my country - Budget: budget-focused — cheapest reliable option matters most - Preference: open to both commercial products and DIY mixes - Fuel carrier: bottles (drink mix) Follow these rules: - Search current availability and prices in my country. - Rank products by price per gram of carbohydrate. - Show carbs, sodium, caffeine, serving size, and cost per 60 g of carbs for each option. - Separate race-day convenience from training-cost value. - Include DIY alternatives using maltodextrin, fructose and sodium citrate. - Do not recommend caffeine powder recipes. - Treat all plans as starting points to test in training — never anything new on race day.
The prompt updates live as you change your answers above.
Whatever your AI suggests is a starting point to test in training — never race on something new.
Step 1
Pick a prompt type
Six jobs your AI can do: find gels near you, compare commercial vs DIY, build a marathon or HYROX plan, troubleshoot your stomach, or write your race-day checklist.
Step 2
Answer the questionnaire
Sport, duration, bodyweight, carb target, sweat level, country, budget and preferences — the prompt personalises itself as you type.
Step 3
Copy it into your AI
Paste into Claude, ChatGPT, Gemini or any assistant with web search. Your AI fetches current, country-aware prices — so the answers stay fresh without this site maintaining a price database.
What's baked into every prompt
Every generated prompt instructs your AI to rank by price per gram of carbohydrate, show sodium and caffeine per serving, separate race-day convenience from training-cost value, include DIY alternatives, refuse caffeine powder recipes, and treat every plan as a starting point to test in training. You get the personalisation; the guardrails come standard.
