Run Pace Calculator description

A calculator that works out your race finish times based on your pace and distance. Any of the three times can be modified to get an instant update of the other fields. Choose from the list of standard race distances or enter your own custom distance.

We also offer an Equivalent Performance page. Here you can enter a time for any race from 400m to Marathon and get a full list of predictions of how well you will do in other distances.

Finally a Speed Converter utility will enable you to quickly convert between pace per mile / kilometer / 400 meters and kilometers per hour, miles per hour and meters per second. Use the custom miles and custom kilometers on the race calculator to convert between miles and kilometer distances.
