Get early accessWhat pace is
Pace is how long it takes to cover a fixed unit of distance, usually shown as minutes and seconds per kilometre or per mile. It is the same information as speed, just expressed the way most runners think about their effort: time per unit of distance rather than distance per unit of time.
How it is calculated
Pace, time, and distance are related by one equation: Time = Pace × Distance. Rearranged, Pace = Time ÷ Distance and Distance = Time ÷ Pace. Give this calculator any two of those values and it solves for the third, converting between kilometres and miles as needed. There is no estimation involved, it is direct arithmetic.
Why runners use it
Use it to plan a run at a specific target pace, to work out what pace a goal finish time requires over a given distance, or to check what pace you actually held on a run once you know the time and distance covered.

Worked example
Take a runner who covers 10K in 50:00.
Dividing 50 minutes by 10 km gives a pace of 5:00 per kilometre. That is the number to picture on an easy long run at this effort, and the same arithmetic works backwards: give this calculator that pace and the distance, and it will hand you the 50:00 finish time.
FAQ
How do I calculate my running pace?
Divide your total time by your total distance. For example, running 5 km in 25 minutes gives a pace of 5:00 per kilometre (25 ÷ 5). This calculator does that division for you, and can also solve for time or distance if you already know the other two values.
What is a good running pace for beginners?
There is no single good pace: it depends on distance, experience, and goals. Most beginner runners doing easy runs fall somewhere around 6:00 to 8:00 per kilometre (about 9:30 to 13:00 per mile), but the right pace is whatever lets you hold a conversation comfortably. Enter your own recent time and distance in this calculator to see your current pace.
How do I convert my pace from km to miles?
Multiply your pace per kilometre by 1.609344 to get your pace per mile, or divide your pace per mile by 1.609344 to get your pace per kilometre. This calculator converts automatically: just switch the unit selector next to the pace field.
What pace do I need to run a marathon in 4 hours?
You need to average about 5:41 per kilometre (roughly 9:09 per mile) to finish a marathon (42.195 km) in exactly 4 hours. Enter 42.195 km as the distance and 4:00:00 as the time in this calculator to get the required pace for any goal marathon time.
What pace is a 50-minute 10K?
A 50-minute 10K works out to a pace of 5:00 per kilometre (50 ÷ 10), or about 8:03 per mile. Enter 10 km and 50:00 into this calculator to confirm, or to see that same pace converted to miles.
How do I convert my pace from min/km to km/h?
Divide 60 by your pace in minutes per kilometre. For example, a 5:00/km pace is 60 ÷ 5 = 12 km/h. This calculator shows pace rather than speed, but you can always get speed by inverting the pace this way.
