A running pace calculator finds minutes per kilometer or mile, finish time, or distance when you know any two of time, distance, and pace—useful for 5K, 10K, half marathon, and marathon planning.
Pace calculations are mathematical estimates. Actual race performance varies by course elevation, weather, terrain, fatigue, and individual fitness level — use as planning estimates, not guaranteed finish times.
Running pace is how long it takes to cover one unit of distance—usually minutes per kilometer (min/km) or minutes per mile (min/mile). The core relationship is pace = time ÷ distance.
If you ran 5 km in 25 minutes, average pace is 5:00 per km (25 ÷ 5). If you know distance and target pace, multiply distance by pace to get finish time. If you know time and pace, divide time by pace to get distance traveled.
This tool switches between three solve modes (pace, time, distance), converts between metric and imperial using 1 mile = 1.609344 km, and shows companion speed in km/h and mph. Race presets use standard distances including exact half marathon (21.0975 km) and marathon (42.195 km) values. Splits list cumulative clock time at each kilometer or mile so you can compare even pacing to how you actually ran.
Enter any two of time, distance, and pace; get the third plus splits and race projections—runs locally, never uploaded.
Average pace equals total elapsed time divided by total distance; imperial and metric units convert via 1.609344 km per mile.
Formula
Pace (min/unit) = total minutes ÷ distance
Finish time = distance × pace
Distance = total minutes ÷ pace
1 mile = 1.609344 kmSelect Pace (from distance + time), Time (from distance + pace), or Distance (from time + pace).
Type distance in km or miles, or tap a chip for 5K, 10K, half marathon, or marathon.
Use mm:ss (e.g. 25:30), hh:mm:ss for long efforts, or decimal minutes. Pace accepts formats like 5:00 per km or per mile.
Results show min/km and min/mile, km/h and mph, projected finish times at standard race distances, and per-km or per-mile splits.

Common real-world scenarios where this tool saves time.
Convert a goal finish time into required average pace, then check per-km splits for even effort.
Use exact 21.0975 km and 42.195 km presets to see clock-time targets at your training pace.
Switch between min/km and min/mile and read km/h or mph without mental arithmetic mid-workout.
Step-by-step chains that connect related tools for common tasks.
| You know | Choose mode | You get |
|---|---|---|
| Distance + finish time | Pace | Average min/km and min/mile plus speed |
| Distance + target pace | Time | Projected finish time and race projections |
| Time + pace | Distance | How far you covered or can cover at that effort |
| Unit | Example pace | Equivalent |
|---|---|---|
| min/km | 5:00 /km | ≈ 8:03 /mile |
| min/mile | 8:00 /mile | ≈ 4:58 /km |
| Speed | 12 km/h | ≈ 7.5 mph at 5:00 /km |

Pick what you want to find—pace, finish time, or distance—then enter the other two. For example, distance and time give pace; distance and pace give finish time. Results show min/km and min/mile plus km/h and mph. All processing happens in your browser; nothing is sent or stored.
Choose Calculate Pace, enter 5 or 10 as distance (or tap the 5K/10K preset), then enter finish time as mm:ss (e.g. 25:30) or decimal minutes. You get average pace in min/km and min/mile.
Pace is minutes per unit of distance. 5 min/km means one kilometer every five minutes. The tool shows both metric and imperial and includes speed in km/h and mph. To convert: min/mile ≈ min/km × 1.609344.
Yes. Choose Calculate Time, enter the race distance (or use Half Marathon / Marathon chips), and your target pace. You get projected finish time plus estimated times for 5K, 10K, and other standard distances at that pace.
Many beginners finish a 5K in 35–40 minutes (7–8 min/km). A comfortable aerobic pace allows conversation. Sub-30 minutes (6 min/km) is a common first racing goal as fitness improves.
