I would like to track my number of continuous days running 1 mile or more.

I begun writing such an app for forerunner 645, sadly there seems to way to tell connect app to display that extra data. Extra data fields or simplay the name for the activity (i.e. "SR#31 210,12km") can be set in the FIT file, but the connect app just ignores this value. A way to tell the connect app the activity name would solve this. I'm quite new to this forum, but I think it might be worth a feature request.
