About this calculator
Our pre-workout carb calculator is a useful tool for endurance athletes, such as runners and cyclists, who need to optimize their carbohydrate intake before a competition or intense training session.
The principle is simple: 1 gram of carbohydrates per kilogram of body weight, consumed about 1 hour before training. This helps ensure that the muscles are loaded with energy and are ready for the effort.
However, it's essential to remember that the exact amount of carbohydrates needed may vary from person to person and depends on various factors, such as fitness level and training intensity.
In addition, it's crucial to avoid hypoglycemia, consuming excessive carbohydrates or consuming them too long before training, which can cause health problems.
