Frequently asked questions
- 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.
