Method and principles

Formula

p = t d
s = t ÷ d; v = d ÷ t

Example and interpretation

Enter the full duration in hours, minutes and seconds, followed by the distance. Running 5 km in 25 minutes gives a pace of 5:00 min/km and speed of 12 km/h. Other distance estimates assume constant pace; they do not account for hills, fatigue or training and are not personalized race predictions.
