I've a forerunner 245 and when I watch on garmin connect my run, I find a difference on the pace graph. If I look pace and lap avg pace.
Ex : https://connect.garmin.com/modern/activity/5607011329
If you look both pace and lap average pace, you'll see that most of the time my instant pace never reach the lap avg pace.
Does anyone have an idea about what this is about ? My runs are exported on strava and on strava it seems fine.
