How this calculator works

Gross kcal = MET × 3.5 × body weight in kg ÷ 200 × minutes. Includes resting expenditure during the activity.

Before you use the result

  • Estimates for general information. They do not diagnose a condition or replace a qualified clinician’s assessment.

What is Running Calorie Calculator?

Running Calorie Calculator helps you estimate running energy expenditure from duration, weight and activity intensity.

The main result is estimated gross energy expenditure. The formula, example and assumptions below explain how to interpret it.

How to use Running Calorie Calculator

Use the example to get familiar with the form, then enter your own figures. Any rates in the example are illustrative. Check the field labels and units before calculating.

  1. Gather body weight (kg), exercise duration (minutes) and activity intensity (MET) (MET). Use values from the same situation or reporting period.
  2. Replace the example body weight with your own value, then complete the other fields. Check the displayed units.
  3. Select Calculate and read estimated gross energy expenditure. Change one input and calculate again to compare a second scenario. Reset restores the original example.
  • Enter body weight in kg, at least 20 and at most 500. Decimals are accepted.
  • Enter exercise duration in minutes, at least 0 and at most 1440. Decimals are accepted.
  • Enter activity intensity (MET) in MET, at least 0.1 and at most 30. Decimals are accepted.

Running Calorie Calculator: a worked example

With the inputs below, the result is 305.025 kcal (estimated gross energy expenditure). Follow the example, then replace these illustrative values with your own.

Example inputs and output
Input or outputExample value
Body weight (kg)70 kg
Exercise duration (minutes)30 minutes
Activity intensity (MET) (MET)8.3 MET
Estimated gross energy expenditure305.025 kcal

Understanding the Running Calorie result

The main output is estimated gross energy expenditure, expressed in kcal. It applies to the inputs and operation you selected.

Displayed results use a readable number of decimal places. When checking a result by hand, keep extra precision until the last step. To compare scenarios, change one input at a time and keep the others fixed.

Running Calorie Calculator: assumptions and common mistakes

A useful estimate starts with the right inputs. Check the following assumptions and limits before applying the result to your situation.

  • Estimates for general information. They do not diagnose a condition or replace a qualified clinician’s assessment.
  • Health estimates are context-dependent. Age, pregnancy, illness, medication and individual measurements can affect interpretation; these tools do not diagnose a condition.

Running Calorie Calculator FAQs

What does Running Calorie Calculator calculate?

Running Calorie Calculator helps you estimate running energy expenditure from duration, weight and activity intensity. Its main output is estimated gross energy expenditure in kcal.

What inputs do I need for Running Calorie Calculator?

You need body weight (kg), exercise duration (minutes) and activity intensity (MET) (MET). Use the field labels and units to match your figures to the formula.

Which formula does Running Calorie Calculator use?

Gross kcal = MET × 3.5 × body weight in kg ÷ 200 × minutes. Includes resting expenditure during the activity.

What is a worked example for Running Calorie Calculator?

Example inputs: Body weight: 70 kg; Exercise duration: 30 minutes; Activity intensity (MET): 8.3 MET. The result is 305.025 kcal (estimated gross energy expenditure).

How should I enter body weight?

Enter body weight in kg, at least 20 and at most 500. Decimals are accepted.

How do I choose exercise duration?

Enter exercise duration in minutes, at least 0 and at most 1440. Decimals are accepted. The example uses 30 minutes; replace it if your circumstances differ.

How should I read estimated gross energy expenditure?

The main output is estimated gross energy expenditure, expressed in kcal. It applies to the inputs and operation you selected.

Why might my Running Calorie Calculator result differ from my records?

Estimates for general information. They do not diagnose a condition or replace a qualified clinician’s assessment. Differences in entered values, units or rounding can also change the comparison.

Can I compare two scenarios in Running Calorie Calculator?

Yes. Note your first estimated gross energy expenditure, change body weight or another input, and select Calculate again. Editing a field clears the old result so it is not mistaken for a new calculation.

Is Running Calorie Calculator free, and where are my inputs calculated?

This calculator is free to use without signing in. Its formula runs in your browser; calculator inputs are not sent to a calculation API. The inputs reset to the example values when you reset the form or start a fresh page.
