It works! I added a toggle to the running app I use Fitocracy to display paces instead of speeds.

The first time I've done anything on a regular android app, and the first time I've really edited an open source project.

Fitocracy was the only app that could show me current speed, average speed, and average speed for less than the whole run without unrealistic hoops. But i was annoyed the speeds were in speeds, not paces.

Hopefully that is just what I need myself. I will try to get it into the original project too as it seems like a worthwhile improvement.
