Calculation breakdown
Method, assumptions and worked example
How it works
Pace = elapsed seconds ÷ distance. Time = pace × distance. Distance = elapsed seconds ÷ pace. One mile is exactly 1.609344 km. Seconds are rounded before formatting, so a pace never displays an invalid seconds value such as 4:60.
Worked example
A 5 km run in 25 minutes has a pace of 5:00/km, approximately 8:03/mile and average speed of 12 km/h.
Using the result
Enter elapsed time if you want stops included; enter moving time if that is your intended comparison. Constant-pace projections ignore fatigue, hills, heat and race conditions. A projection is not a training prescription.
Frequently asked questions
Can I calculate a race finish time?
Choose Time, enter race distance and your planned pace.
Does it handle miles and kilometers?
Yes. Both pace equivalents are shown using the exact mile conversion.
