Fuelog: Endurance Fueling

Your training plan tells you what to do. Fuelog works out what to eat: carb targets that move with your load, and a race-day plan split by leg.

Most nutrition apps were built for dieting. Fuelog is built for fueling.

THE ENDURANCE ENGINE

PERIODIZED CARBOHYDRATE Your daily carb target is calculated from intensity-weighted training hours and where you are in the season - off-season, base, build, peak, taper or race week - anywhere from 3 to 12 g/kg. A rest day and a five-hour ride are not the same day, and a single multiplier cannot express that.

CARBOHYDRATE PROTECTED, NOT LEFT OVER Most apps set protein, then fat, and hand carbohydrate whatever remains. For a lifter that is right. Fuelog reserves carbohydrate first for endurance athletes, then protein, then fat - and if the calorie budget cannot hold all three, it shows you the exact shortfall instead of quietly shaving carbs.

RACE-DAY FUELING, LEG BY LEG Choose sprint, Olympic, 70.3 or full distance, enter your expected splits, and Fuelog builds the plan: carbs per hour, fluid and sodium for each leg. Rates differ by discipline - the bike carries the most, the run less, the swim none - and every rate is capped by the carb rate you have actually practiced in training, not a number off a forum.

GUT TRAINING Enter where you fuel now and where you want to be. Fuelog lays out the ramp - roughly +10 g/h every two and a half weeks - and the week each step starts. If the race is too close to close the gap, it says so and gives you the rate that is reachable.

SWEAT-RATE TEST Weigh in before and after a session, enter what you drank, and Fuelog calculates your sweat rate in liters per hour, then uses it for the fluid and sodium in your race plan.

ENERGY AVAILABILITY Intake minus exercise energy, divided by your lean mass. Most tracking apps never calculate it. Fuelog shows it every day.

CARB LOADING AND MIXED SOURCES When a long race is 1-2 days out, your target moves on its own. Above 60 g/h your plan flags that a single-source product will not absorb fast enough and gives you the glucose-to-fructose ratio to look for.

EVERYDAY LOGGING - Photo logging: point at your plate and AI reads the food and the portion - Voice and text logging, plus a barcode scanner - An AI coach that sees today's sessions, your phase, your race date and your carb target before it answers - AI meal plans, recipes and grocery lists built to your targets - Workout tracking and AI-built training programs - Micronutrients, blood work scanning and InBody body-composition tracking

WEARABLES Syncs with Apple Health, Whoop and Garmin. Fuelog reads what your watch actually recorded and subtracts the resting energy you would have burned anyway, so training is not counted twice.
