See what the free plus version has to offer (!): https://vermail.nl/datarun-plus/ . For Vivoactive 3 and FR645(m) users in the plus version a larger custom font is used! For full flexibility see the manual of Datarun premium at https://vermail.nl/datarun-premium/ 
I don't develop this datafield anymore and I will not add any watches.

This is a datafield based on the Flexirunner datafield, which isn't supported since 2016. I've made some adjustments to it:
- the numbers of laps has been replaced by the current time;
- the current pace is averaged over 5 seconds;
- a battery status icon has been added
- support for Fenix 5 and 5x, Forerunner 935, Vivoactive 3, Approach S60 has been added

I've decided to stop developping this app. I have put a lot of hours in a "plus"-version of this app however, based on user feature-requests. It has options for a black background, permanent backlight, ETA-forecast, Stryd power and more. 
However, it is only for the newer watches. You can find it here: https://apps.garmin.com/en-US/apps/913eab77-333f-4666-8451-da97e59b0d99

This datafield is meant to be placed in a single view (so filling up the whole watchface). It is showing the main metrics for running, like elapsed time, elapsed distance, current heartrate, current pace, current cadance, average pace en and running pace for the current lap. The running pace for the current lap is the average pace for the periods in the current lap that speed was more than 2 m/s. 
These are the default settings, but one can make changes; for example to see lap time and lap distance. One can change the contents of the fields through Garmin Express (Garmin Connect app should work, but doesn't always work!). 

Known bugs:
- one user has indicates that his Vivoactive HR has a black background and a black datascreen. This is not really a bug, it is an unfavourable combination of device and app-settings, as it is only one report. If you use a dark background globally, than this app doesn't work well. You will need my Datarun-plus app if you want that.

P.S.: when you experience a bug, then contact me through the contact option on this page!
