How it works
How to use the running pace calculator
Enter time or pace
Use a target finish time to calculate the required pace, or enter a pace to estimate your finish time.
Check your splits
Use pace, speed and checkpoint times to turn the result into a practical training or race-day target.
Running pace explained
What is running pace?
Running pace is the time required to cover a unit of distance. It is commonly shown as minutes per kilometre or minutes per mile. A lower pace number means a faster running speed.
Speed expresses the same performance as distance per unit of time. This calculator shows both formats so you can convert between pace, speed and finish time without doing the maths manually.
PaceTime ÷ distance
50 minutes ÷ 10 km = 5:00 min/km.
Finish timePace × distance
5:00 min/km × 10 km = 50:00.
SpeedDistance ÷ time
10 km ÷ 0.833 hours = 12.0 km/h.

Using your result
How to use pace for training and race planning
A calculated pace is a mathematical target rather than a guarantee of what you can sustain. Course profile, weather, surface, fatigue, fueling and pacing strategy can all affect real-world pace.
For a goal race, use the calculator to identify the average pace required and the split table to make that target easier to monitor. For training, enter a known pace to see the equivalent speed and projected time for a selected distance.
FAQ
Running pace calculator FAQ
How do I calculate my running pace?
Divide your total running time by the distance covered. For example, 50 minutes for 10 km equals 5:00 per kilometre.
Can I calculate finish time from pace?
Yes. Select Pace, enter your pace per kilometre or mile, and the calculator will estimate finish time for the chosen distance.
Can I use miles instead of kilometres?
Yes. Custom distances can be entered in either unit, and the result always shows both min/km and min/mile.
Does the calculator account for hills, weather or fatigue?
No. It assumes an even average pace. Actual race pace can vary with terrain, conditions, fatigue and strategy.
What pace do I need for a marathon or half marathon goal?
Select the race distance and enter your target finish time. The calculator will show the required average pace and checkpoint splits.
