Average Speed Calculator

Work out your average speed over a whole trip from the distance covered and the time it took — including any stops. Results come in km/h, mph and m/s, with your running pace too.

What “Average Speed” Really Means

Average speed is the total distance divided by the total time — not the average of your speeds along the way.

Average speed = Total distance ÷ Total time

Because it uses total elapsed time, it counts every red light, rest stop and coffee break. That’s why your car’s trip average is always lower than the speed you actually drive at.

Average Speed vs. Instantaneous Speed

Your speedometer shows instantaneous speed — how fast you’re going right now. Average speed smooths all of that into a single number for the journey. A trip where you sprint then stop can have a modest average even if your top speed was high.

From a Real Route

For an accurate average you need the real distance travelled. Trace your route on the map with the distance calculator, then drop the total in here. Runners can convert the pace shown above with the pace converter, and if you know two of speed, distance and time, the speed distance time calculator solves for the third.
