If you know your pace in either of these metrics, this tool will do all the conversion for you and help you figure out your finish time based on the metric you’ve selected in step 1 of this tool. No more Googling how many kilometers are in one mile or vice versa, let this tool do all the heavy lifting for you.

There are also built in buttons in the Admin section to help you convert a set distance from miles to kilometers and vice versa.

No more fumbling to enter numbers for your pace after your run. Tap the buttons to increase and decrease time to see what your finish times would be for each race type!

Most tools also require you to hit a “calculate” button to get your finish time or pace. This Coda doc automatically re-calculates your finish time and pace right after you edit your pace per mile, finish time, and distance. Get the numbers you need right away from your run.
