How many calories does cycling burn? Tables and calculator
Cycling is one of the most efficient calorie-burning exercises. How many you actually burn depends on your weight, intensity, duration, and riding conditions. Here are concrete numbers and practical tips.
Calorie burn by intensity
Approximate calories burned per hour for a 75 kg rider:
- Easy pace (15–20 km/h) — 400–500 kcal/h
- Moderate pace (20–25 km/h) — 500–700 kcal/h
- Hard pace (25–30 km/h) — 700–900 kcal/h
- Racing pace (30+ km/h) — 900–1200 kcal/h
Heavier riders burn more calories at the same speed. A 90 kg rider at moderate pace burns roughly 20% more than a 75 kg rider.
Indoor vs outdoor
Trainer sessions often feel harder but may show slightly lower calorie counts because there's no wind resistance, coasting, or terrain variation. Power-based calorie estimates (from a smart trainer or power meter) are more accurate than heart-rate estimates because they measure actual mechanical work.
How to increase calorie burn
- Add intervals — short high-intensity efforts spike energy expenditure and create an afterburn effect (EPOC).
- Ride longer, not just harder — duration is the biggest lever. A 3-hour easy ride burns more total calories than a 45-minute hard one.
- Choose hilly routes — climbing demands more power and burns more calories per kilometre.
A note on accuracy
Calorie estimates from watches and apps can be off by 20–30%. If you're tracking calories for weight management, use power-based estimates when available and treat all numbers as approximations. Consistency over time matters more than single-session precision.
