How pace is calculated
pace = time ÷ distance
Example: a 5K (3.1 mi) in 28:30 is a pace of 9:12 per mile or 5:43 per km – 6.5 mph. Switch the calculator to Time to get a finish time from a target pace, or to Distance to see how far you get in a given time.
Race distances
| Race | Miles | Kilometers |
|---|---|---|
| 5K | 3.11 | 5 |
| 10K | 6.21 | 10 |
| Half marathon | 13.11 | 21.0975 |
| Marathon | 26.22 | 42.195 |
Using the splits
The table below the result shows where you should be after each mile at an even pace. Most runners finish faster with even or slightly negative splits – the second half a little quicker than the first – than by starting fast.
