GPS and Pace irregularity

[prenaud]

How can there be such a big difference? Same course, a few seconds slower in terms of time, but big difference with distance and pace... I use a Pixel 3a. This course is definitely 3km.

Same just happened to me, pace was tracking as much slower, and as a result, the distance was much less than usual. Any idea why this is happening?

I'm glad I'm not the only one. This is from last summer using a Xiaomi Mi Band 4...

Got the distance right this morning. Can someone explain to me the 34'43" Low Pace? I know the 4'45" Pace is accurate. Unfortunately... 🤣
