Frequently asked questions

How do I calculate my running speed?

Divide the distance covered by your total time — for example, 5km in 25 minutes is a speed of 12 km/h.

What's a good average running speed?

Recreational runners often average 8-12 km/h, while competitive distance runners can sustain 15-20+ km/h — it varies enormously by fitness level and distance.

How is speed related to pace?

Speed and pace are reciprocals — speed is distance per unit time (km/h), while pace is time per unit distance (min/km). This calculator shows both.
