  1. Pace = time ÷ distance = 3000 s ÷ 10 km = 5:00 min/km.
  2. In miles: 8:03 min/mi.
  3. Speed = 12.00 km/h (7.46 mph).

How to use the pace calculator

  1. 1Choose kilometers or miles for the distance.
  2. 2Enter the distance you ran.
  3. 3Enter the time as hours, minutes and seconds.
  4. 4Read your pace per km and per mile, plus speed.

Pace and speed are the same fact, flipped

Pace answers “how long per unit of distance?” and speed answers “how much distance per unit of time?” — reciprocals of each other. A faster run means a lower pace number but a higher speed.

Frequently asked questions

What is running pace?

Pace is how long it takes to cover one unit of distance — minutes per kilometre or per mile. A 5:00 min/km pace means each kilometre takes five minutes. It's the runner's-eye view of speed.

How do I convert pace to speed?

Speed is distance over time, pace is time over distance — they're reciprocals. This calculator shows both: a 5:00 min/km pace is 12 km/h. Divide 60 by your min/km to get km/h.

What pace do I need for a target time?

Divide your goal time by the distance. For a sub-2-hour half marathon (21.1 km), that's 120 min ÷ 21.1 ≈ 5:41 min/km. Enter the distance and your goal time here to check it.
