FAQ
How do I calculate running pace?
Divide your finish time by the distance. Example: 25:00 for 5K is 5:00 per kilometre. Use Distance + Time mode on this calculator.
Try this example →What is the difference between pace and speed?
Pace is time per unit distance (e.g. min/km). Speed is distance per unit time (e.g. km/h). They describe the same effort in inverse units.
How do I convert min/km to min/mile?
Multiply min/km by 1.609344 (or use this calculator — both units are always shown).
What pace do I need for a sub-2-hour half marathon?
A 1:59:59 half needs about 5:41 per kilometre (9:09 per mile). Use Distance + Pace or the Half Marathon target presets.
Try this example →What pace do I need for a 4-hour marathon?
A 4:00:00 marathon is about 5:41 per kilometre (9:09 per mile). Try the Sub 4:00 marathon shortcut.
