Hi
I have a problem with some historic data from my forerunner 405. I've got a fairly large number of activities that have duplicate splits added in and, presumably as a result, no map data is available. The extra splits all get given a lap number of 1 so on a 20 mile run I'll have 21*lap 1 and 1* every subsequent lap. The splits labelled 1 will be all be different - actually there are just 2 sets of 20 laps!?
There doesn't seem to be any consistency about which activity these duplicates have appeared on although I'm pretty sure its been on activities where I have uploaded from the device more than once (I use a default upload not selecting activities to upload).
Not sure this description makes sense but does anyone know why this has happened? Anything I can do about this?
