Hello,
I am using a forerunner 10
Recently, I realized that all races, before August 9th have no altitude profile displayed.
I am pretty sure that this races were previously displayed correctly, but no more altitude profile.
I can only see the speed/distance but not the altitude.
I tried to re-download some of the races from the watch, no change.
Only races since August 11 are displayed correctly.
Any idea what's going wrong ?
Thanks for helping
