What is pace?
Pace is the time you need for one kilometre, given in minutes and seconds per kilometre (min/km). It is the counterpart of speed in km/h: the lower the pace, the faster you run. Runners plan with pace because GPS watches show it directly and it is easy to hold in training.
The maths is simple: pace = time ÷ distance. The other way round, finish time = pace × distance. To convert to km/h, divide 60 by the pace in minutes. A half marathon is 21.0975 km, a marathon 42.195 km – small differences in pace add up to several minutes over these distances.
Two directions
- Pace from time
- Enter distance and time run – you get pace, km/h and min/mile.
- Finish time from pace
- Enter distance and target pace – you get the finish time and all split times.

Using pace well
Planning tips
- 1Run evenlyA steady pace saves energy. Starting the first half too fast usually costs more time at the end than it gained early on.
- 2Know your splitsThe table shows when you should pass each kilometre – handy for your watch or a wristband.
- 3A projection is not a forecastHolding the same pace over a longer distance is harder. The projection only shows the result at an unchanged pace.
- 4Measure the distanceGPS watches often deviate slightly on race courses. For planning, the official course length counts.
Frequently asked questions about pace
Conversion, finish times and splits
How do I convert pace to km/h?
Divide 60 by the pace in minutes. 5:00 min/km is 60 ÷ 5 = 12 km/h, 6:00 min/km is 10 km/h. Convert seconds to minutes first: 5:30 min/km is 5.5 minutes, so 60 ÷ 5.5 ≈ 10.91 km/h.
What pace do I need for a sub-4-hour marathon?
To run 42.195 km in 4:00:00 you need a pace of 5:41 min/km (exactly 5:41.3). If you want to be safely under 4 hours, plan a little faster.
How long does 10 km take at a 5:30 pace?
At 5:30 min/km, 10 km take exactly 55 minutes. Choose "Finish time from pace" in the calculator and enter your pace – it shows the time for any distance.
What is the difference between pace and speed?
Pace is time per distance (min/km), speed is distance per time (km/h). Both describe the same tempo; runners usually use pace, cyclists km/h.
How do I convert min/km to min/mile?
One mile is 1.609344 km. Multiply the pace by this factor: 5:00 min/km is about 8:03 min/mile. The calculator shows both values.
