Speed is heavily influenced by wind, gradient, drafting, and road surface. A 30 km/h ride into a headwind burns far more than 30 km/h with a tailwind. Power is the only reliable metric.
Normalized Power (NP) reflects physiological cost of variable efforts but should not be used directly for calorie calculation. Use average power (work done / time) for energy expenditure.
Power meter calories include your basal metabolic rate during the ride. For net exercise calories above rest, subtract approximately 1 kcal/kg/hr of body weight.
Calculate cycling energy expenditure from average power output and ride duration. Power-based calorie estimation is the gold standard in cycling, far more accurate than speed or heart rate methods because it directly measures mechanical work output.
