CarbTrail: Fuel & Hydration

Stop guessing your fueling. CarbTrail turns any planned route into a minute-by-minute drink plan tuned to your body, your sport and the live weather, then shows you how to mix the exact same drink yourself for a fraction of the branded price. One app does what others only do in parts: route, timeline, recipe, and savings, together. ROUTE TO PLAN IN SECONDS - Import a planned route (GPX from your favorite route planner or device) or just enter distance and climb. - CarbTrail derives your duration and effort automatically, no spreadsheets. - Pulls live weather for race day so heat and conditions shape the plan. YOUR PERSONAL CARB TIMELINE - A clear minute-by-minute schedule of when and how much to drink. - Tuned to your weight, sport, intensity, sweat and gut tolerance. - Carbs, fluid and sodium per hour, shown as clear per-hour bars and a fueling curve. - Ready-to-drink bottles: carbs and water mixed in one — CarbTrail tells you exactly how many bottles cover your whole tour. MIX YOUR OWN DRINK - An exact DIY recipe: grams of carbs and salt, in the right amount of water. - Start with plain kitchen staples — add maltodextrin later for a gentler mix. - See the cost per bottle and a running counter of how much you have saved. - One total mix for the whole tour plus a pre-ride checklist — bottles mixed, pre-hydrated, electrolytes packed on hot days. REAL SAVINGS - A homemade bottle can cost around 20 cents — branded servings often cost ten times more. - That is roughly one fifteenth the price of a premium drink mix, for the same fuel. - Energy needs no brand. BACKED BY SPORTS SCIENCE - Built on established endurance-nutrition guidance (ACSM/AND/DC 2016, Jeukendrup and more). - Respects real gut-absorption ceilings: 60, 90 and 120 g of carbs per hour. - Accounts for glucose-to-fructose ratio, sweat and sodium, heat, and sport-specific gut tolerance. FOR BEGINNERS AND PROS - New to fueling? Follow a safe, clear plan and learn as you go. - Experienced? Dial in every variable and push toward your gut ceiling. - A built-in Learn section explains the why behind every number, with sources. DESIGNED TO BE USED - Fast, focused, dark interface. Four simple tabs: Plan, Recipe, Learn, Settings. - Available in English and German. SIMPLE, FAIR PRICING - Your first 3 fueling plans are free, no account needed. - Then a single one-time lifetime unlock. No subscription, ever. - Most athletes save that back within their first few homemade bottles. Great for cyclists, runners, triathletes, trail and gravel riders, hikers and anyone who fuels with carbs and wants to fuel smarter while spending less.
