How is my daily goal calculated? Your base goal comes from your weight. On training days it increases with duration and intensity, and by another 10% if hot climate is on. If you've done the sweat test, every calculation uses your own sweat rate.
How do I do the sweat test? In the Training tab, enter your weight before and after training, how much you drank during it, and its duration. Hidro calculates your hourly sweat rate and how much to drink to recover.
