Pace, time and distance
Pace = time ÷ distance; time = pace × distance; distance = time ÷ pace. One mile is 1.609344 km. Pace is shown in minutes and seconds per selected unit.

Reading the race chart
The chart uses 5 km, 10 km, 21.0975 km and 42.195 km. Each time assumes your pace stays constant for the entire distance; terrain, fatigue and conditions are not modelled.

A few useful answers
Does the chart predict my marathon performance?
No. It shows the time needed to cover each distance at a constant pace. It does not predict whether you can sustain that pace.
Can I calculate distance from time and pace?
Yes. Select Calculate distance and enter duration and pace. Switching kilometres and miles preserves the physical distance and converts pace.
