Running Calorie Calculator

Background.

Ask how many calories a run burned and the honest answer depends on whether you mean per minute or per mile. Per minute, faster is costlier: the Adult Compendium of Physical Activities rates running at 5 mph at 8.3 METs, 6 mph at 9.8 and 8 mph at 11.8. Per mile, the picture nearly flattens. A 70 kg runner covering a mile at 5 mph is credited with about 122 kcal; at 8 mph, about 108. The faster runner works harder but for fewer minutes, and spends less of the total on the resting metabolism that ticks over regardless.

That makes distance the main lever for anyone running to burn energy. Speed raises the rate, but a longer route adds minutes, and minutes add calories faster than shaving seconds off each mile does.

The estimate rests on the metabolic equivalent. One MET is the energy cost of sitting at rest, 3.5 millilitres of oxygen per kilogram of body weight each minute; multiply the pace's MET by your weight and your minutes, convert the oxygen to kilocalories, and you have a gross figure for the run with resting energy included.

Weight counts as much as pace, because running is the work of carrying your body forward. Thirty minutes at 6 mph comes to 463.05 kcal for a 90 kg runner and about 283 kcal for one weighing 55 kg.

Only three paces are offered, and real runs rarely sit exactly on one. Hills, trails, headwinds and heat all add cost that the level-ground MET values leave out, and a trained runner often moves more economically than a beginner at the same speed. Read the result as an average for someone of your weight, not a measurement of you.

What is running calorie calculator?

A running calorie estimate converts time spent running into energy using a MET value for the pace, the ratio of the activity's energy cost to resting metabolism. The paces offered are 5 mph (a 12-minute mile, about 7:27 per kilometre), 6 mph (a 10-minute mile, about 6:13 per kilometre) and 8 mph (a 7:30 mile, about 4:40 per kilometre), rated at 8.3, 9.8 and 11.8 METs. The answer is in kilocalories and is gross, so it includes the resting energy you would have spent over the same minutes.

How to use this calculator.

1. 01Enter your weight in kilograms, ideally a recent reading; 176 lb is about 80 kg.
2. 02Enter the minutes you were actually running. Leave out the warm-up walk and any time stopped at crossings, or the total will be overstated.
3. 03Choose the pace closest to your average. Divide your minutes by your miles or kilometres to find it: 10 minutes a mile, or about 6:13 per kilometre, is the 6 mph option.
4. 04If your pace falls between two options, run the page with both and take a figure in between. On a hilly route, lean toward the higher result.

The formula.

Calories = MET × 3.5 × weight (kg) ÷ 200 × minutes, where the MET is 8.3, 9.8 or 11.8 for the pace you choose. The 3.5 is the resting oxygen uptake that defines one MET, in millilitres per kilogram per minute, and dividing by 200 converts that oxygen to kilocalories, since a litre of oxygen used yields close to 5 kcal. Put together, each MET costs 0.0175 kcal per kilogram per minute, so at 6 mph a runner spends 0.1715 kcal per kilogram every minute. Weight and minutes enter in direct proportion. Pace enters through the MET, but less than proportionally: 8 mph is 60% faster than 5 mph yet carries only 42% more METs, which is why the quicker pace costs less per mile. Gradient, surface, wind and temperature are not modelled.
