FAQ
Frequently Asked Questions
What is pace in running?
Pace is the time needed to cover one kilometer (or one mile). It is expressed as minutes per kilometer (min/km). A pace of 5:30 min/km means you run one kilometer in 5 minutes and 30 seconds.
How do I convert between pace and speed?
Speed (km/h) = 60 / pace (min/km). A pace of 6:00 min/km equals 10 km/h. A pace of 5:00 min/km equals 12 km/h. Faster pace means lower number.
Why does my GPS watch show a different pace from the calculator?
The calculator divides the time by the distance you enter; for a marathon that is the official course length of 42.195 km (half marathon 21.0975 km). Race courses are measured along the shortest possible line; because nobody runs the ideal line through every bend, runners overtake and GPS is imprecise, your watch usually shows a little more distance at the finish. Example: for a 3:30:00 marathon the calculator gives 4:59 min/km, but if your watch measures 42.6 km, you need to run about 4:56 min/km according to the watch. So plan a buffer of a few seconds per kilometer.

What is the Pace Calculator?
The pace calculator computes running pace (min/km), speed (km/h) and finish time for a given distance.
How does the Pace Calculator work?
Enter two of the three values: distance, time or pace. The calculator determines the third. Useful for training and race planning: 5 km, 10 km, half marathon, marathon.
Key Data and Facts
Marathon: 42.195 km. Half marathon: 21.0975 km. Pace 5:00 min/km = 12 km/h. Pace 6:00 min/km = 10 km/h. Men's marathon world record: approx. 2:00:35.
Step-by-Step Guide
How to use the pace calculator step by step: 1. Enter two of three values: distance, time or pace (min/km). The calculator works out the third value. 2. Understand pace: Pace tells you how many minutes you need for one kilometre. A lower pace = faster. 3. Convert pace into speed: km/h = 60 / pace (min/km). So a pace of 5:00 = 12 km/h, a pace of 6:00 = 10 km/h, a pace of 4:00 = 15 km/h. 4. Standard distances: 5 km, 10 km, half marathon (21.0975 km), marathon (42.195 km). 5. Calculate target times: A marathon under 4 hours = a pace of 5:41 min/km. A half marathon in 2 hours = a pace of 5:41 min/km. 10 km in 50 minutes = a pace of 5:00 min/km. 6. Training tips: A long run is about 30-60 seconds slower than your race pace. Intervals are about 20-40 seconds faster. Tip: A steady pace leads to better results than starting too fast.
Calculation Example
Marathon in 3:45:00 over 42.195 km: pace = 225 min / 42.195 = 5:20 min/km = 11.25 km/h.
