How it's calculated
Pace = time ÷ distance, Speed = distance ÷ time
time = total elapsed time, distance = distance covered. Pace shown as min/km or min/mi; speed as km/h or mph.
Worked examples
| Distance | Time | Pace/mile | Pace/km |
|---|---|---|---|
| 5K | 25:00 | 8:03 | 5:00 |
| 10K | 55:00 | 8:51 | 5:30 |
| Half marathon | 2:00:00 | 9:09 | 5:41 |
Common questions
How do I convert pace to speed?
Speed is distance over time, while pace is time over distance, so they're inverses. The tool shows both from one input.
Can I use this for cycling?
Yes. Cyclists usually watch speed in km/h or mph, which the calculator reports alongside the running paces.
