How to use it

  1. Pace: enter a distance and the time it took. You get your pace per mile and per kilometer.
  2. Time: enter a distance and a pace. You get your finish time.
  3. Distance: enter a time and a pace. You get how far you'll go.

How pace is calculated

Pace is time divided by distance. If you run 5 kilometers in 28 minutes, your pace is 28 ÷ 5 = 5.6 minutes, or 5:36 per kilometer. One mile is 1.609 kilometers, so the same run is about 9:01 per mile.

What to do with your pace

One pace isn't right for every run. Most of your running should be slower than race pace. The training pace calculator turns a recent race into easy, tempo and interval paces, and the race time predictor shows what that race suggests for other distances. Ready to train? Pick a free training plan.

Common questions

How do I calculate my running pace?
Divide your time by your distance. A 5K (3.1 miles) in 28:00 is 28 ÷ 3.1 = about 9:01 per mile, or 28 ÷ 5 = 5:36 per kilometer.
How do I convert pace per mile to pace per kilometer?
Divide the pace per mile by 1.609. A 9:00 mile is about 5:36 per kilometer. To go the other way, multiply the pace per kilometer by 1.609.
What pace do I need for a 2-hour half marathon?
About 9:09 per mile, or 5:41 per kilometer.
What pace do I need for a 4-hour marathon?
About 9:09 per mile, or 5:41 per kilometer, the same pace as a 2-hour half marathon held for twice as long.
