Hi, I am looking for (techie) advice.... I use a Garmin Fenix to record my runs. It's a pretty good device except that it doesn't message me to warn me that the battery is low like my fitbit used to do.
one other annoying feature is that I've been running mostly 5, 10 and 15km so the distance setting is in km.
I have run 3 1/2 marathon distances and always run a little over to be certain that I covered the full distance. None of these times are recorded. It may be that I need to change from km to miles to record the 1/2 marathon distance but that doesn't seem like a robust solution.
I have definately run over 21.09km (1/2 marathon) 3 times this year but none show in the performance records.
