Pace Calculator IT
Enter a distance and time to get your pace per km and per mile, your speed, and predicted race times.
How it works
Enter the distance you covered and the time it took, then choose kilometres or miles. The calculator divides your time by the distance to give pace (minutes per km and per mile), converts it to speed (km/h and mph), and projects your finish time at 5K, 10K, half-marathon and marathon at the same effort.
Frequently asked questions
What is running pace?
Pace is how long it takes to cover one unit of distance — for example 5 minutes per kilometre. It is the inverse of speed, and a lower number means you are running faster.
How do I calculate my pace?
Divide your total time by the distance. For 10 km in 50 minutes, that is 3,000 seconds ÷ 10 km = 300 seconds, or 5:00 per km.
What is the difference between pace and speed?
Speed measures distance per hour (km/h or mph); pace measures time per distance (min/km or min/mi). They describe the same effort from opposite angles — 12 km/h is the same as a 5:00/km pace.
How do I convert min/km to min/mile?
Multiply your per‑kilometre pace by 1.609. A 5:00/km pace becomes about 8:03 per mile. To go the other way, divide the per‑mile pace by 1.609.
What is a good 5K pace?
It varies widely. Many recreational runners finish a 5K around 6:00–7:00 per km (roughly 30–35 minutes), while a sub‑25‑minute 5K needs about 5:00 per km. The best pace is one you can sustain for the whole distance.
What pace do I need for a sub‑4‑hour marathon?
A 4‑hour marathon is about 5:41 per km (9:09 per mile) held steadily for 42.195 km. The calculator’s predicted finish times show what your current pace projects to at marathon distance.
Does pace stay the same at longer distances?
Usually not — most runners slow slightly as distance increases. The race predictions here assume an even effort, so treat the longer‑distance estimates as optimistic targets rather than guarantees.
Can I use this for walking or cycling?
Yes. The math is the same for any activity — enter the distance and time and you will get pace and speed. Walking paces are typically 9–12 min/km; cycling is better read as speed in km/h or mph.
Pace Calculator
This pace calculator turns a distance and a finish time into your running pace — the minutes and seconds it takes to cover one kilometre or one mile — along with your speed and projected times for popular race distances. It works for running, walking, cycling and rowing, in either metric or imperial units.
What is pace?
Pace is the amount of time spent per unit of distance, usually written as minutes and seconds per kilometre (min/km) or per mile (min/mi). A lower pace number means you are moving faster. Pace is the inverse of speed: where speed answers “how far per hour,” pace answers “how long per km.” Runners track pace because it is easier to hold a steady min/km target on the road than to watch a speedometer.
The pace formula
Pace is simply total time divided by distance:
Pace = Total time ÷ Distance and Speed = Distance ÷ Total time
To convert between units, 1 mile equals 1.609 km, so pace per mile = pace per km × 1.609.
Worked example
| Step | Calculation | Result |
|---|---|---|
| Distance and time | 10 km in 50 min 00 s | 3,000 s over 10 km |
| Pace per km | 3000 s ÷ 10 km | 300 s = 5:00 /km |
| Pace per mile | 5:00 × 1.609 | 8:03 /mi |
| Speed | 10 km ÷ (50 ÷ 60) h | 12.0 km/h (7.46 mph) |
Typical paces
| Activity | Pace per km | Pace per mile |
|---|---|---|
| Brisk walk | ~9:00–11:00 | ~14:30–17:40 |
| Easy jog | ~6:30–8:00 | ~10:30–12:50 |
| Recreational 5K runner | ~5:30–6:30 | ~8:50–10:30 |
| Sub–4‑hour marathoner | ~5:40 | ~9:09 |
| Elite marathoner | ~2:55 | ~4:42 |
Who uses a pace calculator?
- Runners setting a target pace for a 5K, 10K, half or full marathon.
- Beginners checking whether their easy runs are actually easy.
- Walkers and hikers estimating how long a route will take.
- Coaches converting between min/km and min/mi for training plans.
- Cyclists and rowers translating a time trial into average speed.
