Running Pace Calculator

Find your running pace and speed.

How it is calculated

Pace per kilometre is time / distance, with distance in kilometres and time in total minutes. Pace per mile is the km pace multiplied by 1.609344. Average speed is distance / (time / 60) in km/h. Paces are written as minutes:seconds, with seconds rounded to the nearest whole second.

Both distance and time must be greater than zero. Time is entered as decimal minutes, so 1 hour 5 minutes is 65, not 1.05. Because the result is an average over the whole distance, it says nothing about how even your splits were.

Worked example

A 10 km run in 55 minutes. Pace per km: 55 / 10 = 5.5 minutes, i.e. 5 minutes and 0.5 × 60 = 30 seconds, shown as 5:30 /km. Per mile: 5.5 × 1.609344 = 8.851 minutes, which is 8:51 /mi. Speed: 10 / (55 / 60) = 10.91 km/h.

Common mistakes

  • Typing the time as hours.minutes (1.30 for 1 h 30 min). The field takes decimal minutes, so enter 90.
  • Entering a distance in miles while treating the km pace as the mile pace. The distance field is in kilometres.
  • Reading 5.5 min/km as 5:50. The decimal part is a fraction of a minute, so 0.5 is 30 seconds.
  • Using a race pace calculated from a measured route that is short or long. A 10.2 km course changes every number.

About this calculator

This calculator converts distance and time into running pace — minutes per kilometre and minutes per mile — plus your average speed. Pace is simply time ÷ distance, but runners think in pace rather than speed because it maps directly onto race splits: a 5:00/km pace means every kilometre should tick by in exactly five minutes if the effort stays even.

Runners and coaches use pace calculators constantly for race planning — converting a goal finish time (say, a sub-4-hour marathon) into the per-kilometre or per-mile splits needed to hit it, checking training run paces against target zones, and comparing performances across different race distances. Enter distance and time to get your pace and speed.
