How Pace Calculator works

Calculate pace, finish time or distance with kilometre and mile conversions, speeds and event references.

The formula

Pace = time ÷ distance. Speed = distance ÷ time. Kilometres and miles use the exact 1.609344 conversion.

A practical example

A 25-minute 5K is 5:00 min/km, about 8:03 min/mile and 12 km/h.

Important limitations

This is steady average pace and does not account for terrain, stops or changing effort.
