How It Works

The formula is: Calories = MET × weight(kg) × time(hours). MET (Metabolic Equivalent of Task) represents how many times more energy the activity uses compared to resting. The MET values used are drawn from the Compendium of Physical Activities: Leisurely (under 16 km/h) = MET 4.0, Moderate (16–19 km/h) = MET 6.8, Vigorous (19–22 km/h) = MET 8.0, Racing (22–26 km/h) = MET 10.0, Very Fast (over 26 km/h) = MET 12.0. Ride duration in hours is derived from the entered distance divided by the typical average speed associated with each intensity band. For example, a 20 km moderate ride at 17.5 km/h takes 20 ÷ 17.5 = 1.143 hours. Calories = 6.8 × 75 × 1.143 ≈ 583 kcal for a 75 kg cyclist. The result reflects gross calories burned (including basal metabolic rate during the activity), which is the standard for exercise calorie reporting.

Examples

Commute or Casual Ride
75 kg cyclist, 20 km at moderate pace — a typical daily commute or leisure outing.
Result: ~466 calories burned in approximately 69 minutes.
Training Ride
80 kg cyclist, 40 km at vigorous pace — a faster-paced fitness training session.
Result: ~1,254 calories burned in approximately 117 minutes.
Competitive Cycling
70 kg cyclist, 50 km at racing pace — an event or time-trial effort.
Result: ~1,458 calories burned in approximately 125 minutes.

Frequently Asked Questions

Does cycling or running burn more calories?
Running burns more calories per hour at similar effort levels due to greater muscle recruitment and the vertical energy cost of each stride against gravity. However, cycling is lower impact so riders often sustain longer sessions without fatigue or injury, which can result in comparable or greater total calorie burns over a training block. For the same duration at moderate effort, running typically burns 20–30% more calories than cycling — but a two-hour ride versus a one-hour run may end up roughly equivalent in total energy expenditure.
Does this apply to stationary bikes?
Yes — MET values for stationary cycling are very similar to outdoor cycling at equivalent effort levels because the metabolic cost depends primarily on work rate rather than equipment. Select the intensity level that matches your perceived exertion on the bike, indoors or outdoors. Bikes with power meters make this more precise: roughly 100–150W corresponds to moderate, 150–200W to vigorous, and 200W+ to racing pace.
Why does the result depend on weight?
Heavier cyclists burn more calories for the same ride because more energy is required to accelerate, sustain speed, and especially to climb with a larger body mass. The MET formula multiplies directly by body weight in kilograms, so a 90 kg rider burns 20% more calories than a 75 kg rider at the same intensity over the same distance. Weight is the single most influential variable in the estimate, more impactful than moderate changes in intensity.
