Cycling Calorie Calculator

Use this Cycling Calorie Calculator to estimate gross calories burned during a bike ride from body weight, duration, distance, ride type, effort level, and optional elevation gain. It also estimates average speed, pace, calories per hour, and calories per distance.

Important: Cycling calorie estimates are approximate. Wind, drafting, terrain, bike type, rolling resistance, stops, body composition, fitness, and riding efficiency can significantly affect actual energy expenditure.

Cycling Calorie Formula

The calculator uses a MET-based calorie model after estimating an activity intensity from the selected ride inputs.

Calories burned = MET × 3.5 × body weight in kg × duration in minutes ÷ 200

MET means metabolic equivalent of task. A larger MET value represents a higher estimated energy cost.

If weight is entered in pounds:

Weight in kg = weight in lb ÷ 2.20462

Average Speed

If distance and duration are entered:

Average speed = distance ÷ time

The calculator uses speed, ride type, effort, and optional elevation information to help select or adjust its estimated intensity.

The published Compendium of Physical Activities contains different MET values for cycling activities ranging from easy leisure riding to vigorous road riding, mountain biking, racing, and stationary cycling.

Worked Example

Suppose a cyclist weighs 70 kg, rides for 60 minutes, and the selected activity corresponds to an estimated 8 METs.

Apply the formula:

Calories = 8 × 3.5 × 70 × 60 ÷ 200

Calories ≈ 588 kcal

The estimated gross energy expenditure is therefore approximately 588 kcal for the hour.

Gross Calories

This MET formula estimates gross energy expenditure, meaning it includes the energy that would have been used at rest during the same period.

Some fitness watches instead display active calories above resting expenditure, so their results may be lower even for the same ride.

Important Notes

• Published MET values are population-level estimates rather than direct measurements of an individual’s metabolism.
• The calculator’s adjusted MET output may differ from a published Compendium value because it also considers selected ride settings.
• Average speed alone does not determine effort. A headwind, steep climb, rough trail, or heavy bicycle can increase workload at the same speed.
• Drafting can reduce aerodynamic resistance and therefore reduce energy demand compared with riding alone.
• Elevation gain can increase workload, but a simple adjustment cannot fully model gradient, descent, wind, and route profile.
• Stops and coasting can make one average MET value less representative of an entire ride.
• Power-meter data can provide a more direct measure of external cycling work, although calorie expenditure still requires physiological assumptions.
• Do not treat estimated exercise calories as an exact amount that must be replaced through food intake.
