Hello,
There is a bug on Garmin Connect, where is is showing Pace as "0:00 min / mi" when the running Pace graph is maximised (screenshot included). This is happening on all of my runs, and on all browsers.
My watch is a Fenix 5X, if that makes any difference. It has been happening for a few weeks at least. ciq.forums.garmin.com/.../1343356.png
