New here so apologies if I am overlooking something but I have sync’d with garmin including historical for all activities, my outdoor rides and indoor rides recorded with my edge unit are showing but my indoor activites recorded with TrainerRoad (and sync’d with garmin) arent showing.
These activities are listed in Garmin as Indoor Cycling but that activity type doesnt seem to exist in intervals.
Concrete example here - for a race on Saturday 31st I forgot to start my Garmin and recorded on my Coros Apex 4 then manually imported via the Garmin Connect web interface. It was pushed to by Garmin to Runalyze, Stryd almost immediately and various other 3rd parties.
If OP manually imported his FIT, it would be pushed to 3rd parties.
