How to Calculate Cycling Speed
What is Cycling Speed?
A cycling speed calculator converts between speed, distance, and time for cycling. It also calculates average speed from GPS data and estimates power output from speed and gradient using aerodynamic drag models.
Step-by-Step Guide
- 1Average speed = Total distance / Total time
- 2Climbing speed is affected by gradient: each 1% gradient adds roughly 4–5 watts/kg of additional resistance
- 3Power required ≈ 0.5 × CdA × air density × speed³ + rolling resistance × weight × speed
Worked Examples
Input
40km in 1h 20min
Result
30 km/h average
40÷1.333 = 30 km/h
