How Many Calories Does Cycling Burn? Tables and Calculation
"How much did I burn?" — every cyclist asks this after a ride. The answer depends on a handful of variables: your weight, intensity, ride time, and even terrain. Here are the actual numbers.
Calorie burn table for cycling
Approximate values for 1 hour of riding on flat terrain:
| Pace | 60 kg | 75 kg | 90 kg |
|---|---|---|---|
| Easy (15 km/h) | 280 kcal | 350 kcal | 420 kcal |
| Moderate (20 km/h) | 400 kcal | 500 kcal | 600 kcal |
| Brisk (25 km/h) | 520 kcal | 650 kcal | 780 kcal |
| Hard (30 km/h) | 680 kcal | 850 kcal | 1020 kcal |
| Race pace (35+ km/h) | 840 kcal | 1050 kcal | 1260 kcal |
What affects calorie burn?
Body mass
The more you weigh, the more you burn — a heavier body needs more energy to move. That's good news early in a weight-loss effort.
Intensity
The most precise indicator is power (watts). Roughly 1 kJ of mechanical energy output equals about 4 kcal of metabolic expenditure (~25% efficiency). If you have a power meter, multiply the kJ reading on your head unit by 4 for a calorie burn accurate to within about 5%.
Terrain
Climbing dramatically increases burn. An hour in the mountains can cost 800–1200 kcal at a moderate pace, versus 400–600 kcal on the flat. Wind works similarly — riding into a headwind raises expenditure by 20–40%.
Temperature
In winter your body spends extra energy on thermoregulation; in heat, on cooling (sweat). Both extremes raise calorie burn by 5–15%.
Cycling vs. running vs. swimming
| Sport | kcal/h (75 kg, moderate effort) |
|---|---|
| Cycling (20 km/h) | ~500 |
| Running (8 km/h) | ~600 |
| Swimming (freestyle) | ~550 |
| Walking (6 km/h) | ~300 |
Cycling loses to running on a per-hour basis, but wins on total burn — because you can sustain 2–3 hours on a bike without much trouble, while running past an hour gets demanding.
How to increase calorie burn
- Intervals — short surges (30–60 s) raise your metabolism for hours after the ride.
- Climbs — riding uphill is a natural interval.
- Longer rides — after 90 minutes, the body shifts toward fat as its primary fuel source.
- Fasted training — controversial, but a short ride (up to 60 min) before breakfast can increase fat oxidation. Don't use it on long rides.
Bottom line: pace and weight get you a rough estimate, but power data gets you a number you can actually trust — and one that's directly tied to the training load you're logging, not just the calories.
