I did a 5000m track run today on a level track.
Looking at the lap data on Garmin connect, there is Avg Pace and Avg GAP. The two paces varies up to about 30 seconds per km different.
The two paces should be identical as the track is level. There is no elevation change shown in the altitude graph.
The pace chart shows the incorrect GAP pace regardless of whether I select Pace or Grade adjusted pace. The lap average pace is correct.
Both Garmin connect web and Android app have the same problem.
This is not the only time this has happened.
It seems to only happen when I select "track run" as the activity.
Has anyone else had this problem or can explain what is happening here ?
Thanks
