Enter a distance and a goal time to get the pace you have to hold, or enter a target pace to get your finish time. Splits in both miles and kilometres. No sign-up.
Cumulative time at each kilometre, holding an even pace.

An even split is the plan. Holding it is the hard part. That's what Steady Pace does by ear, with a tone that rises the moment you drift slow and falls when you drift fast.
Running pace is time divided by distance. Take your finish time in seconds, divide by the distance, and you get seconds per kilometre or per mile. For a 25:00 5K that's 1,500 seconds over 5 km, which is 5:00 per kilometre, or 8:03 per mile. The calculator above does this both ways: give it a goal time and it returns the pace; give it a pace and it returns the finish time, plus a split for every kilometre or mile.
A good pace is the one you can hold for the whole distance. It depends on you, the day, and the terrain. As rough anchors: many recreational runners cover a 5K somewhere between 6:00 and 7:00 per kilometre (9:39 to 11:16 per mile); a sub-2:00 half marathon needs 5:41 per kilometre (9:09 per mile), the same pace as a sub-4:00 marathon. Use the pace charts to see the number behind any finish time.
Knowing the number is the easy half. Holding it, through hills, fatigue, and the excitement of the first mile, is the part that decides your race. A watch tells you your pace a few seconds late, so you chase it. Steady Pace plays a continuous tone instead: it rises when you slow below your target and falls when you speed up, so you correct by ear, in the moment, without looking down. Read how to run a steady pace or how to stop going out too fast.
Set the pace from this calculator as your target in Steady Pace and hold it by ear with a tone that rises when you slow and falls when you speed up.
Multiply your pace per kilometre by 1.609. A pace of 5:00 per kilometre is 5 × 1.609 = 8.05 minutes per mile, or about 8:03. The calculator shows both at once, so you never have to do it by hand.
5:41 per kilometre, or 9:09 per mile, held for the full 21.1 km. That is also the exact pace for a sub-4:00 marathon, which makes it a useful number to memorise. See the half marathon pacing guide.
No. It gives you an even pace over the flat-equivalent distance. On a hilly course you run by effort rather than by holding the exact number up every climb. That is one reason an audio tone helps here: you hear how far off you are and can spend effort sensibly.
