Half Marathon Calorie Calculator Formula

The calculation for estimating calories burned during a half marathon can be expressed using the following formula:

Calories Burned = 0.75 * Distance * Weight

Let's break down the formula:

  • Calories Burned: This is the total number of calories you can expect to burn during the half marathon.
  • Distance: Refers to the distance of the half marathon you completed. It serves as a key factor in calculating calorie expenditure.
  • Weight: Your weight is another important factor as it influences the amount of energy required to cover the distance.

By multiplying the distance and weight by a constant factor of 0.75, the formula provides a reasonable estimation of calorie burn.

Illustrative Example

Let's consider an example to understand how to use the Half Marathon Calorie Calculator effectively:

Suppose you completed a half marathon with a distance of 21.1 kilometers and you weigh 65 kilograms. By plugging these values into the calculator, we can calculate the calories burned as follows:

Calories Burned = 0.75 * 21.1 * 65 = 1001.88

Therefore, according to the calculator, you burned approximately 1001.88 calories during the half marathon.
