Frequently Asked Questions

How does the running pace calculator work?

Pick what you want to find—pace, finish time, or distance—then enter the other two. For example: distance and time give you pace; distance and pace give you finish time. Results show in min/km and min/mile. Use the preset chips for common distances or type any value. All processing happens in your browser; nothing is sent or stored.

How do I calculate my 5K or 10K pace?

Choose 'Calculate Pace', enter 5 or 10 as distance (or tap the 5K/10K chip), then enter your finish time in mm:ss (e.g. 25:30) or plain minutes. You get average pace in min/km and min/mile.

What is min per km and min per mile?

Pace is minutes per unit of distance. 5 min/km means one kilometer every 5 minutes. The tool shows both metric and imperial so you can train or race in either. Speed in km/h and mph is included.

Can I get a half marathon or marathon finish time from my pace?

Yes. Choose 'Calculate Time', enter the race distance (or use a preset chip), and your target pace. You get the projected finish time. The projections section also shows estimated times for standard race distances at your current pace.

Is this pace calculator free and private?

Yes. No signup required. Everything runs in your browser and no data is sent or stored.

What Is Running Pace Calculator?

Running Pace Calculator is a tool that converts between pace (min/km or min/mile), speed (km/h or mph), and finish time for any distance — letting runners calculate their target pace for a goal race time, or predict their finish time at a given pace.

How it works: Pace (min/km) = 60 ÷ speed (km/h). Finish time = pace × distance. All three variables are linked — enter any two and the calculator solves for the third. It supports standard race distances (5K, 10K, half marathon, marathon) and custom distances.

When you need it: Users typically reach for Running Pace Calculator when calculating what pace to run to finish a 5K in under 25 minutes, planning splits for a marathon goal time, converting treadmill speed to outdoor pace, or working out how fast a recent run was based on distance and time.

Key Facts

Formula:
Pace (min/km) = Time (min) ÷ Distance (km)
Speed conversion:
Speed (km/h) = 60 ÷ Pace (min/km)
Units:
min/km or min/mile, km/h or mph
Race distances:
5K, 10K, half marathon (21.1km), marathon (42.2km), custom

These are even-pace estimates. In practice, most runners run negative splits (slightly faster in the second half) or use a pacing strategy with hills. Add 5–15 seconds per km for hilly courses. Race-day finish times also depend on weather, hydration, and elevation.
