Free calculators for athletes
Three quick calculators built on the same numbers as the Sweatmeal app and the methodology page. They run in your browser: nothing is saved, sent or tracked. General nutrition information, not medical advice.
Training day calories and macros
Calories, protein, carbs and fat for a training day against a rest day, from the same formula the app uses.
Open the calculatorCarbs per hour
Grams of carbohydrate per hour for a run or a ride, by duration and intensity, with the total and a gel count.
Open the calculatorCarb loading
Grams of carbs per day in the last two days before a marathon or long race, plus the race-morning meal.
Open the calculatorIn the app, this comes from your real training
The calculators use typical values. Sweatmeal uses what you actually did, read from your wearable, and sets each day's calories and macros from it.
