About this doc

## Purpose of a Running Pace Calculator

You just got off the treadmill and know your pace per mile or kilometer. This Coda doc automatically tells you what your finish time would be for popular race types like marathons, 10Ks, 5Ks, and more. If you are training for a special race that is outside one of the “traditional” race types (like the Bronx 10 Mile), you can add your custom race to the “Race Types” table with the number of miles or kilometers for that race. The pace calculator will then calculate your finish time for that unique race.

Other features of this pace calculator Coda doc:

• Find how fast your pace should be if you want to finish a race by a certain finish time. For example, this doc will help you find what your per mile or per kilometer pace should be a for a sub-2:30 marathon time.
• Find your pace for any distance run given you know the distance (in milers or kilometers) and finish time
• See your finish time for popular races and your own custom distances given you know your pace per mile or kilometer

## Easily Convert Between Miles and Kilometers

If you are using a running app like Runkeeper or Strava, you can see your pace in miles or kilometers. 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.

## Built for Mobile

Unlike other running pace calculators, this Coda doc is meant to be used on mobile. If you just finished a run and try to use an existing pace calculator website, you’ll find that you have to manually enter in numbers for your pace. With this Coda doc, you can simply hit the +5s and +1m buttons to increase your pace time by 5 seconds and 1 minute (respectively (there are also buttons for -5s and -1m). 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.
