I used Garmin Connect Mobile to transfer some Garmin running segments on my watch (f5 plus Ti. - fw 3.10)
Then :
I started a run activity ( not a course / « parcours »)
i ran very close to the location of the start, and perform the segment.
this on 4 differents segment.
I ran those 2/3 times close to the start of each segment,
but the segment was never detected.
Another point, I am also wondering how to get the actual list of segment currently on the watch, and possibly to remove some of those individually.
