You can use this pace calculator to easily find your time, pace, or distance for any run. Simply enter two of the three and then click the Calculate button. For example: Enter a time and a distance and your pace will be calculated automatically. The calculator works with both American and metric units so you can easily convert your 10K time into a per mile pace, etc. Also, you'll find standard race distances (marathon, half-marathon, etc.) in the distance dropdown box. And, if you don't see the distance you need there, you can enter a custom one. Happy calculating!
