Possibility to edit custom data field in Garmin Connect

it's offtopic here, but you can try to download the fit file, edit it, delete the original activity, then import the fit file.

Thanks for reply, this  sounds like a hack, I was wondering if there is any better option, since any default metrics can be edited inline, but custom cannot

No. You can't really edit the default metrics either. Like you can't change the recorded pace or HR. You can trim the activity and change it's type or name. But not the recorded "facts"

Well akshually you can edit time or distance in the Connect App, and average pace will be recalculated accordingly.

You can actually edit a lot more stuff on the Connect website, like HR (avg and max), total ascent/descent, best pace, calories, and cadence (avg/max).

You can't edit avg pace anywhere, probably because Garmin wants to calculate that from time and distance.

Yeah, that's what I meant, we can edit lots of default metrics, but was wondering if custom field value could be edited, since in SDK documentation couldn't find any mention of any property on creating a custom field like 'editable' or so 

because the SDK is about how you do things from Monkey C code in the app, not about what can be done to the fit file in the Garmin Connect app :) But again: no, there's no official way to edit it
