Running pace calculator

With two of the three figures (distance, time and pace) you get the third. Use it to plan a race or check a training run.

The 5K, 10K, half marathon and marathon distances are built in.

How it's calculated

Pace = time ÷ distance, in minutes and seconds per km.
Time = pace × distance.
Distance = time ÷ pace. Average speed is the distance divided by the hours.

An example

10 km in 50 minutes is a pace of 5:00 per km, at 12 km/h.

A half marathon (21,1 km) at 5:30 per km finishes in 1:56:02.

Frequently asked questions

How do I work out my pace per km?

Turn the time into minutes and divide by the kilometres. 10 km in 55 minutes is 5,5 minutes per km, or 5:30.

What is a good pace for a beginner?

One that still lets you talk while you run. That pace drops as your fitness builds.

How long is a marathon?

42,195 km (26,2 miles). A half marathon is half that.
