Pace Calculator

Work out your running or walking pace from a distance and a time, or turn it around to find the finish time for a pace or the distance you will cover. Pace is shown per mile and per kilometer together, with one-tap presets for 5K, 10K, half marathon and marathon.

Quick examples

      Formula

      Pace = time ÷ distance
      Time = pace × distance
      Distance = time ÷ pace
      Pace per mile = pace per km × 1.609344

      How to use it

      1. Choose what to solve for: pace, time or distance.
      2. Enter the other two. Type times as h:mm:ss or mm:ss, and pick miles or kilometers for the distance.
      3. Read the answer, with pace in both units and your average speed.

      Race distances

      A 5K is 3.107 miles and a 10K is 6.214 miles. A half marathon is 13.109 miles (21.0975 km) and a marathon is 26.219 miles (42.195 km). The presets use the exact metric distances, so a result will differ by a few seconds from one worked out with 13.1 or 26.2 miles.

      Pace versus speed

      Runners talk in pace — minutes per mile — while treadmills show speed in miles per hour. To convert, divide 60 by one to get the other: 6 mph is a 10:00 mile, 7.5 mph is an 8:00 mile and 10 mph is a 6:00 mile.

      Questions people ask

      What pace is a 25-minute 5K?

      8:03 per mile, or 5:00 per kilometer.

      What pace do I need for a 30-minute 5K?

      9:39 per mile, which is exactly 6:00 per kilometer, or about 6.2 mph on a treadmill.

      How do I convert pace per km to pace per mile?

      Multiply by 1.609. A 5:00 per km pace is 5 × 1.609 = 8.05 minutes, which is 8:03 per mile.
