Marathon pace chart calculator

Get your personal marathon pace chart, with km (or miles) lap times

Do you have to run a Marathon and want to calculate your average pace and speed?
Use our calculator and also get lap times at 5, 10, 15, 20, 21.1, 25, 30, 35 and 40 km.
For example, if you want to finish the Marathon in 4 hours, your running pace should be 5'41"/km. You should complete 10 km in 56'53", 30 km in 2h50'38".
If you prefer, you can choose to have lap times in miles. With the same example of a 4 hour marathon, the average pace is 9'09"/mi and you will have to complete 10 miles in 1h31'31", 20 miles in 3h03'02".

Marathon pace chart calculator: select the unit and insert the marathon time to get your pace (in min/km and min/mi) and your speed (in km/h and mph) and to get your personal marathon pace chart.
A table will show the travel times at different distances keeping the same pace.
