Garmin have announced that training effect can now be calculated from third party apps (phew no more dual recording!) is it possible for intervals to sync a fit file to GC? For example a fit file generated by a wahoo bike computer (either direct to intervals or via Strava).
I did some poking around online and looked at the docs I have and I didn’t find any way to do this. That doesn’t mean it isn’t possible. I have emailed their support.
I’ve done more digging, and the thing for Training Effect is the manufacturer field in the fit file. Anything that they deem a virtual platform will work (Tacx, TrainerRoad etc) but anything that they consider hardware won’t - if you change the manufacturer to Wahoo using fitfiletools Training Effect will not be calculated.
As the content is identical, I can only assume this is a decision for competition reasons.
So, even if intervals.icu could upload a fit file to Garmin, it would need to transform the original source (Strava, Wahoo etc) to change the Manufacturer to intervals.icu (which would require a request to Garmin).
I think I saw it was also mentioned that in order for this to happen, the user must own (and have in their GC account) a Garmin device which calculates Training Effect.
