How to Calculate Your Running Pace

What running pace means

Pace is how long it takes to cover one kilometre or one mile, written as minutes and seconds — 5:30 min/km, say. Unlike speed, a lower number is faster. It is the language runners use because it maps straight onto a race: hold 5:30 min/km for 10 km and you finish in 55 minutes.

Calculate it from a run

Divide your time by your distance. A 5 km run in 30 minutes is 30 ÷ 5 = 6.0, which is 6:00 min/km. A 10 km in 52 minutes is 52 ÷ 10 = 5.2 min/km; the 0.2 minutes is 0.2 × 60 = 12 seconds, so 5:12 min/km. That last conversion — decimal minutes into seconds — is where most mistakes hide.

Pace vs speed

Speed is distance over time (km/h); pace is time over distance (min/km). They are two views of the same run. To switch, divide 60 by the other: 6:00 min/km means 60 ÷ 6 = 10 km/h, and 12 km/h means 60 ÷ 12 = 5:00 min/km. Treadmills usually show speed, races usually talk pace.

Using pace to train and race

Once you know your paces, training gets specific: an easy run sits well below race pace, a threshold effort just below your one-hour pace, and intervals faster still. On race day, the biggest gain is even pacing — start at your target pace, not faster. Runners who bank time early almost always give it back, and more, in the final kilometres.

Frequently asked questions

What is a good running pace for beginners?

There is no single number — a good easy pace is one at which you can still talk. Many new runners settle around 7:00–8:00 min/km, and consistency matters far more than speed at the start.

How do I convert min/km to min/mile?

Multiply your min/km pace by 1.609. A 6:00 min/km works out to about 9:39 min/mile.

Should I run the whole race at the same pace?

Aim for even or slightly negative splits — the same pace throughout, or a touch faster at the end. It almost always beats starting fast and fading.
