What is the running pace calculator?

Enter your pace per kilometer (min:sec) to get speed (km/h, mph), pace per mile, and predicted finish times for 5K, 10K, half marathon, and full marathon.

How to use

  1. 1 Enter your target pace per km in minutes and seconds.
  2. 2 Read the speed (km/h, mph) and per-mile pace.
  3. 3 Check predicted finish times for each distance.

Highlights

Pace ↔ speed

Instantly turns pace into km/h and mph.

Finish prediction

Estimates 5K, 10K, half, and full times at your pace.

Mile pace

Shows per-mile pace alongside per-km.

常见问题

Pace vs speed?+

Pace is time per distance (min/km); speed is distance per time (km/h). They are reciprocals.

What speed is 5 min/km?+

5:00/km equals 12 km/h.

Are finish times accurate?+

They assume you hold the entered pace the whole way; real results vary with late-race slowdown.
