How do I convert pace to speed?

Speed (km/h) = 60 / pace (min/km). For example, 5:00 min/km = 60 / 5 = 12 km/h.

What speed is a 4 minute km?

A 4:00 min/km pace equals 15 km/h (9.3 mph). This is a very fast pace, typical of competitive club runners.

A 6:00 min/km pace equals 10 km/h (6.2 mph). This is a comfortable pace for many recreational runners.

Convert between running pace (min/km) and speed (km/h or mph).

Convert from

Pace (minutes)

Pace (seconds)

Speed (km/h) = 3600 / Pace (seconds per km)

To convert to mph, divide km/h by 1.60934.

To convert min/km to min/mile, multiply by 1.60934.
