Cycling Speed Calculator
Rode a distance and know the time? Get your average speed in km/h and mph, your time per 10 km, and what a full 100 km would take at exactly that pace.
Your numbers
Hours : minutes : seconds — moving time if you have it.

How it works
Average speed is the most honest summary of a ride and the most misleading. It hides every hill, headwind and café stop inside one number, and it uses moving time only if that is what you entered. Two riders can share a 28 km/h average with completely different rides: one steady into the wind, one surfing a tailwind home.
The per-10 km figure is the cyclist’s version of a runner’s pace — the number to watch on long rides, because it exposes fading early. If your 10 km blocks slow steadily across a ride, the last block is telling you about fuelling, not fitness.
Good practice & limits
- Compare averages only against rides on the same route in similar wind. Speed is weather, written as a number.
- For training load, time in the saddle beats distance: three hours is three hours in any weather.
- A 1 km/h average gain over a season, on the same loop, is a big improvement.
