The Marathon Carb Loading Calculator helps runners determine the appropriate amount of carbohydrates to consume before a marathon. This calculator is useful for athletes, nutritionists, and coaches to optimize energy levels for endurance events.

## Inputs, Formulas, and Calculations

## Inputs:

**Body Weight (kg)**: The runner’s body weight in kilograms.**Carbohydrate Loading Percentage (%)**: The percentage of body weight to be consumed as carbohydrates (typically 8-12%).

## Carbohydrate Intake Calculation:

The formula to calculate the carbohydrate intake is:

[ \text{Carbohydrate Intake (grams)} = \text{Body Weight (kg)} \times \text{Carbohydrate Loading Percentage (\%)} ]

## Example Calculation

**Inputs**:

- Body Weight (( \text{BW} )): 70 kg
- Carbohydrate Loading Percentage (( \text{CLP} )): 10%

## Step-by-Step Calculation:

**Calculate Carbohydrate Intake**:

- Using the formula:

[\text{Carbohydrate Intake} = 70 \times 10 = 700 \, \text{grams}]

## Summary:

For a runner weighing 70 kg, consuming carbohydrates at 10% of their body weight, the total carbohydrate intake should be 700 grams.

## Conclusion

The Marathon Carb Loading Calculator is an essential tool for runners and their coaches, ensuring that the optimal amount of carbohydrates is consumed before a marathon. By inputting the runner’s body weight and desired carbohydrate loading percentage, this calculator provides a precise calculation of carbohydrate intake, helping to enhance performance and endurance on race day.
