About the pace calculator
Pace is how long it takes you to cover one unit of distance, usually minutes per kilometer or minutes per mile. Any two of pace, time and distance give you the third, so this calculator has three tabs: find your pace from a distance and time, find your finish time from a distance and pace, or find the distance you will cover in a given time at a given pace.
Every result also shows your pace in both kilometers and miles, your speed in km/h and mph, a split table with the elapsed time at each kilometer or mile marker, and the finish times you would post for common race distances at the same pace.
The race table assumes an even pace for the whole distance. In practice most runners slow down over longer distances, so use it as a planning aid rather than a prediction.
Formula
- Pace = time ÷ distance
- Time = pace × distance
- Distance = time ÷ pace
- 1 mile = 1.609344 km
Example
Running 5 km in 25 minutes is a pace of 25 ÷ 5 = 5:00 per kilometer, or 8:03 per mile. At that pace a 10K takes 50:00 and a marathon takes 3:30:59.
