Calories Burned Biking Calculator

Background.

Two people who each went for a half-hour bike ride may have done very different amounts of work. Rolling to the shops at a gentle pace and racing along the same road are both "riding a bike", yet the hard ride can cost three times the energy, because air resistance climbs steeply with speed and every extra kilometre an hour has to be bought with more force on the pedals.

The estimate here sorts rides into three effort levels taken from the Adult Compendium of Physical Activities and expresses each as a MET, a multiple of the energy you use sitting still: 4.0 for leisure riding, 8.0 for moderate effort and 12.0 for vigorous riding. Combined with your body weight and the minutes you spent pedalling, that gives a gross calorie figure, meaning it includes the energy your body would have used at rest over the same time.

Picking the right level matters far more than anything else you type in. For a 70 kg rider, half an hour comes to 147 kcal at leisure, 294 kcal at moderate effort and 441 kcal riding hard.

What the effort levels cannot see is the road. A headwind, a long climb or a bumpy gravel track all raise the cost at a given speed, while sitting in a group's slipstream or coasting downhill lowers it. Choose the level by how hard the ride felt rather than by the number on the speedometer, and treat the answer as an average for riders of your weight, not a measurement of you.

What is calories burned biking calculator?

A cycling calorie estimate converts riding time into energy expenditure using metabolic equivalents. One MET is resting energy use, set at 3.5 millilitres of oxygen per kilogram of body weight per minute; an activity rated 8.0 METs uses eight times that. The three levels offered here, 4.0, 8.0 and 12.0, are the Compendium's way of grouping rides from easy to hard. The result is in kilocalories and counts everything burned during the ride, resting energy included.

How to use this calculator.

1. 01Type your own weight in kilograms, without the bike or any luggage; the equation scales the energy to your body alone.
2. 02Enter moving time only. Many cycling apps show moving time separately from elapsed time, and the difference, time at traffic lights or café stops, should be left out.
3. 03Choose the effort level by how the ride felt: leisure if you could chat freely, moderate if conversation came in short sentences, vigorous if you were breathing too hard to talk.
4. 04Read the calorie figure and the MET shown with it. For a ride that mixed hard climbs with easy stretches, run the parts separately and add them.

The formula.

Energy (kcal) = MET × 3.5 × weight (kg) × minutes ÷ 200. Multiplying the MET by 3.5 gives oxygen use in millilitres per kilogram per minute, and multiplying by weight turns that into millilitres per minute for your whole body. The division by 200 does two things at once: it converts millilitres to litres and applies the round figure of 5 kcal released for each litre of oxygen used. Every term multiplies, so the answer is directly proportional to each of them: double the ride time and the calories double, move from leisure (4.0) to vigorous (12.0) and they triple. Nothing is subtracted for resting metabolism, which is why the result is a gross figure.
