# How to calculate Calories in KCal from time and distance running

I am working on a school project and I need a simple equation for calculating the number of Calories burnt when running from time(in milliseconds, could be seconds, minutes, and so on..) and distance(in meters, could be in kilometers, and so on..). Do I need a bodymass? if yes it can be included. Can somebody help me? I've spent 3 days of googling and didn't find a proper answer.

• You might have more luck if you were able to include heart-rate data. Oct 9, 2016 at 19:51
• Hi @Niall, one’s heart rate has little to no bearing on their energy expenditure, as one’s heart rate can vary depending on many factors. Greg Doucette elaborates on this point: m.youtube.com/watch?v=SLkCSkhgKp8 Aug 17, 2020 at 17:05

Here you go. You just need to have avarage HR and time

One of the more standard and most accurate ways to calculate the equation is to use the calorie expenditure formula below . It comes from the Journal of Sports Sciences and provides a formula for each gender.

Men use the following formula:

Calories Burned = [(Age x 0.2017) — (Weight x 0.09036) + (Heart Rate x 0.6309) — 55.0969] x Time / 4.184.

Women use the following formula:

Calories Burned = [(Age x 0.074) — (Weight x 0.05741) + (Heart Rate x 0.4472) — 20.4022] x Time / 4.184.

or less accurate formula:

Running (total calories spent per mile)

.75 x your weight (in lbs.)

Running (Net calories spent per mile)
