The Pace Calculator can be used to calculate (1) your pace if you know both the distance and the time, (2) the distance you'll cover given your pace and time, and (3)  your time if you input your pace and distance.

To use the calculator, click on the pull down menu "Calculate for" and select one the following: pace, time or distance. Under the boxes that are now highlighted in red/brown enter the other two pieces of information. Leave the Green box empty. Press the "Calculate" button. If you make a mistake press "Clear" to start again.
