Easy Running Pace Calculator

Running calculator: work out your pace, your time or your distance from the other two, and see the times you would hit at every distance along the way.

Enter any two of the three — time, distance and pace — and the app gives you the third one straight away. Change a value, tap calculate, and it recalculates on the spot. Kilometres or miles, your choice.

Pace calculator
Your pace per kilometre or per mile, from the distance you ran and the time it took you.

Time calculator
How long a distance will take you at the pace you have in mind. Useful for planning a long run or setting a target for a race.

Distance calculator
How far you get in a given time at a given pace.

Race prediction
From your reference run, a full table of times: every distance from the first kilometre up to the one you entered, with the time you would cross it in at that same pace. Handy for working out your splits, or for seeing what a 5K or a 10K would look like at the pace you are running now.

Kilometres or miles
One switch changes everything: the distances, the pace and the whole prediction table.

Made for planning and checking, not for tracking. There is no GPS and nothing to set up: you type the numbers and get the answer, which is exactly what you want when you are preparing a session, splitting a race or working out what that training run actually meant.

The prediction assumes you hold the same pace the whole way. Real races depend on the course, the conditions and your training.
