Convert pace, time and distance in min/km or min/mi. Per-km splits, speed and equivalents on classic distances.
Convert pace, time and distance in min/km or min/mi with automatic splits.
Running pace calculator in min/km and min/mi: time, distance, speed and splits. Simple, accurate and free.
Fill any two fields; the third is computed automatically.
Running pace is the time it takes you to cover one unit of distance. In the US and the UK it is usually expressed in minutes per mile (min/mile), while most of the rest of the world runs in minutes per kilometre (min/km). Either way, pace is the runner's native unit, whereas cyclists tend to think in miles or kilometres per hour.
The maths is a single division: total time divided by distance covered. An hour for 6 miles gives 60 ÷ 6 = 10:00 min/mile. It gets messy as soon as the numbers stop being round, which is exactly what the pace calculator above is for: enter any two values and the third is worked out for you, in either unit.
They describe the same thing from opposite directions. A pace of 8:00 min/mile is the same as 7.5 mph, and 5:00 min/km is the same as 12 km/h. Pace goes down as speed goes up, which trips up most beginners at first.
For running, pace is simply more useful, because it projects straight onto a race distance. At 8:00 min/mile you know a 10K takes just under 50 minutes without reaching for a calculator. Doing the same projection from mph takes an extra step every time.
A training plan is never run at a single pace. Coaches generally work with four broad efforts, from slowest to fastest:
There is no universal benchmark, since pace depends on age, training history and goal. As a rough guide, recreational runners often sit around 10:00 to 12:00 min/mile (6:00 to 7:30 min/km) on easy runs, regular runners around 8:00 to 10:00 min/mile, and experienced club runners below 7:15 min/mile. The only number that really matters is your own, compared with where it was a few months ago.
Divide 60 by your pace expressed in decimal minutes. A pace of 5:30 min/km is 5.5 minutes, so 60 ÷ 5.5 = 10.9 km/h. An 8:30 min/mile pace is 8.5 minutes, so 60 ÷ 8.5 = 7.06 mph. The calculator displays pace and speed side by side, so no manual conversion is needed.
It is total time divided by total distance. It hides everything that happened in between: two runs with an identical average pace can be run very differently, one perfectly even and the other as a negative split. That is why mile or kilometre splits tell you far more about a run than the average alone.
Use whatever your races and your running community use. Miles dominate in the United States and the United Kingdom, kilometres almost everywhere else. If you are following a plan written in the other unit, or travelling to race abroad, the calculator switches between min/mile and min/km so nothing gets lost in conversion.
