A running pace calculator with three modes. Pace from distance and time turns a run into pace per km, pace per mile and average speed. Pace to speed and back converts a single value, so 9 km/h becomes a 6:40 per km pace and a 7:15 mile becomes 8.28 mph. Finish time from pace shows how long a mile, 5K, 10K, half marathon or marathon takes at a target pace. A treadmill speed to pace chart sits below the calculator, and everything runs in your browser.
How to use
- Pick a mode: Pace from distance and time, Pace to speed and back, or Finish time from pace.
- For your pace, enter the distance (or tap 5K, 10K, Half marathon or Marathon) and your total time as HH:MM:SS.
- To convert, type one value and choose its unit: min per km, min per mile, km/h or mph. Paces can be typed as 5:30, 5'30 or 5.5.
- For a finish time, enter a target pace per km or per mile and a race distance.
- Results update as you type. For common treadmill speeds, read the speed to pace chart below the calculator.
Examples
- 10 km in 50:00 gives a pace of 5:00 per km, 8:03 per mile, and 12 km/h.
- 9 km/h is a pace of 6:40 per km, or 10:44 per mile.
- 10 mph is a 6:00 mile pace, which is 3:44 per km.
- A 7:15 mile pace is 8.28 mph, or 13.32 km/h.
- At 5:00 per km a half marathon (21.0975 km) takes 1:45:29.
- A marathon (42.195 km) in 4:00:00 needs a pace of 5:41 per km, about 9:09 per mile.
FAQs
- How do I calculate my running pace?
- Divide your total time by the distance. 50 minutes for 10 km is 5 minutes per km, written 5:00. The calculator does this for you and also gives your pace per mile and your average speed in km/h and mph.
- How do I convert pace to speed?
- Divide 60 by your pace in minutes. A 5:00 per km pace is 60 ÷ 5 = 12 km/h, and a 6:00 mile is 60 ÷ 6 = 10 mph. When the pace has seconds, turn them into decimal minutes first: 7:15 is 7.25 minutes, so 60 ÷ 7.25 = 8.28 mph.
- How do I convert km/h to pace per km?
- Divide 60 by the speed to get minutes per km. 9 km/h gives 60 ÷ 9 = 6.67 minutes, which is 6:40 per km. The same works in miles: 6 mph is a 10:00 mile. The Pace to speed and back mode and the chart below do this for any speed.
- How do I work out a race finish time from my pace?
- Multiply your pace by the distance. At 5:30 per km a 10K takes 55:00 and a half marathon takes 1:56:02. Use the Finish time from pace mode, tap a race distance, and set the pace per km or per mile, whichever the race uses.
- How do I enter my time or pace?
- Type total times as HH:MM:SS, for example 1:05:30. Shorter forms work too: 50:00 is minutes and seconds, and a plain number like 90 is seconds. Paces are typed as M:SS (5:30), in watch notation (5'30), or as decimal minutes (5.5), and the calculator shows how it read a decimal pace.
- What is the difference between pace and speed?
- Pace is how long it takes to cover one unit of distance, shown as minutes and seconds per km or per mile. Speed is how much distance you cover per hour, shown in km/h or mph. A lower pace and a higher speed both mean faster.
- How is pace per mile converted from kilometres?
- One mile equals 1.609344 kilometres, so a pace per mile is the pace per km multiplied by 1.609344. A 5:00 per km pace is 8:03 per mile.
- Can I use this for walking, cycling or treadmill workouts?
- Yes. The math is the same for any activity over a distance, so the results apply to walking, cycling and swimming too. The chart below the calculator lists treadmill speeds from 6 to 20 km/h and 3 to 12 mph with the pace each one equals.
- Why do I get an error message?
- Every value must be a positive number in a recognised format. Check for an empty field, a zero, or seconds above 59 in a value like 5:75. The message under the inputs says which value needs fixing.
