Running Pace
WEBCalculate pace, time or distance for your run, plus even splits.
Cumulative time at each km, assuming an even pace.
| Mark | Split | Total |
|---|---|---|
| 1 km | 5:00 | 5:00 |
| 2 km | 5:00 | 10:00 |
| 3 km | 5:00 | 15:00 |
| 4 km | 5:00 | 20:00 |
| 5 km | 5:00 | 25:00 |
Splits assume you hold an even pace the whole way. Real races drift with hills, wind and effort.
What is the Running Pace tool?
This running pace calculator turns any two of distance, time and pace into the third, and shows the answer in min/km, min/mi, km/h and mph at once. Enter how far you ran and how long it took to get your pace; enter your target pace and a distance to get a finish time; or enter a time and a pace to see how far that carries you. Everything recalculates the moment you type, in kilometres or miles.
It also builds an even-split table: the cumulative time you should hit at every kilometre or mile if you hold a steady pace. Split tables are how runners plan a goal race — knowing you need to pass 5 km at 25:00 and 10 km at 50:00 keeps you from going out too fast, the most common way to blow up a long run. Fractional distances like a 5.2 km parkrun or a half marathon get a final partial leg so the total lines up exactly.
Your numbers never leave the page: the calculator runs entirely in your browser, so nothing is uploaded and no account is needed, and once the page has loaded it works offline. It is free, phone-friendly, and switches between km and miles in one tap — handy for training logs that mix the two. Pace math is simple but easy to fumble mid-run; letting the tool do it means your splits are right before you lace up.
How to use the Running Pace
- Pick what you want to find: pace, time or distance.
- Choose your distance unit — kilometres or miles.
- Enter the two values you know (for example distance and time to get pace).
- Read the pace, speed and finish time — they update instantly as you type.
- Scroll to the even-split table to see the cumulative time to hit at each km or mile.
Frequently asked questions
How do I calculate running pace?
Pace is your total time divided by the distance you ran. For example, 50 minutes over 10 km is 5:00 per kilometre. Enter your distance and time above and the calculator works out the pace — in both min/km and min/mi — for you.
What is a good running pace?
It depends on your fitness and the distance. A common beginner 5 km pace is around 7:00–8:00 per kilometre, while trained runners hold 4:00–5:00. Rather than chase a number, use pace to run consistently and improve against your own past times.
How do I convert min/km to min/mile?
One mile is 1.609 km, so a per-mile pace is your per-kilometre pace multiplied by 1.609. This tool shows both at once, so you never have to do the conversion by hand — switch the unit and the whole result updates.
What are even splits?
Even splits mean running each segment of your race in roughly the same time. The split table here shows the cumulative time to hit at each kilometre or mile if you keep a steady pace — a simple plan that stops you starting too fast and fading late.
Is the pace calculator free and private?
Yes. It is free with no sign-up, and every calculation happens in your browser — your times and distances are never uploaded or stored. Once the page has loaded it even works without an internet connection.
