About the Pace Calculator

Running pace tells you how long each kilometre or mile takes. Enter a distance and a target time to find your pace, then see projected times for common race distances.

  2. Enter your Target Time in hours (H), minutes (M) and seconds (S).

Formula and method

Pace = total time ÷ distance. Speed is distance ÷ time. One mile equals 1.609 km.

Worked example

Running 10 km in 50 minutes is a pace of 5:00 per km (8:03 per mile), a speed of 12 km/h.

Tips

  • Build weekly distance gradually, by no more than about 10 percent per week.
  • Do most runs at an easy, conversational pace and add one faster session per week.
