How do I calculate running pace per km?

Divide your finish time in minutes by the distance in kilometres. For example, a 50-minute 10K is 50 ÷ 10 = 5:00 per km. Enter distance and time in the pace calculator and it works out pace, finish time, or distance from any two values.

How do I convert mile pace to km pace?

Use the pace converter to switch between min/mile and min/km instantly — it also shows speed in km/h and mph. For a quick estimate, multiply your per-mile pace by 0.621371 to get an approximate per-km equivalent.

What is the formula for running pace?

Pace = time ÷ distance. If you know your target pace and race distance, multiply pace by distance to estimate finish time. If you know time and distance, divide time by distance to get average pace.

How do I plan even splits for a race?

Enter your race distance and target finish time or pace. The calculator shows kilometre splits — cumulative times at each km — so you can check whether you are on track during the race.
