First and foremost, I really wish that Garmin would partner with My Whoosh like they do with Zwift. Then this problem would go away.
Here is the deal. I am using a Wahoo Kickr Core cycling trainer and I can pair my Forerunner 955 to that no problem and record speed, power, distance etc. What I don't get is elevation and GPS.
I can download the activity file afterwards from MyWhoosh that contains GPS data, elevation etc. What I'd like to do is just add that to the existing activity. I can - in theory though not tried it - merge the two .fit files and then create a new manual activity. But that seems like a lot of faffing around.
Any thoughts or suggestions?
