Use this running pace calculator to estimate your pace, average speed, and finish time from a known race or training result. It works well for common goals such as a 5K, 10K, half marathon, marathon, and classic track distances.
Runners often think in min/km or min/mi, while watches and training plans may show km/h or mph. This calculator helps you switch between those views quickly, compare target paces, and check what a finish time means over a chosen distance.
Running Pace Calculator FAQ
What does a running pace calculator do?
A running pace calculator helps you convert between distance, time, pace, and speed. It is useful for race planning, training sessions, pacing strategy, and checking what a recent result means at a different distance.
How do you calculate running pace?
Running pace is calculated as time ÷ distance. For example, if you run 10 km in 50 minutes, your pace is 5:00 per km. If you run 5 miles in 40 minutes, your pace is 8:00 per mile.
What is the difference between pace and speed?
Pace is usually shown as minutes per kilometre or minutes per mile, while speed is shown as km/h or mph. Runners often train by pace, but treadmills and some watches may display speed instead.
Can I use this for 5K, 10K, half marathon, and marathon pace?
Yes. The calculator is suitable for common race distances including 5K, 10K, half marathon, and marathon. You can also use presets for classic track distances and custom distances for workouts or route planning.
How do I convert min/km to km/h or min/mile to mph?
You can convert pace to speed by taking the reciprocal with the correct unit factor. In practice, most runners use a calculator because it is faster and reduces mistakes, especially when switching between min/km, min/mi, km/h, and mph.
Is average pace enough for race planning?
Average pace is a useful starting point, but real race pacing also depends on elevation, terrain, weather, fueling, and how evenly you distribute effort. For longer races, many runners compare both target average pace and split-by-split pacing.
