Excuse me if I’m missing something, but why do you need the internet at all? Can’t you collect your location with a GPS watch as you run and just handle the gpx file offline when you get home?

Unless you’re looking to share location with others as you run - in which case your request makes sense.

Would OwnTracks meet your requirements? https://owntracks.org/

An app that does what I'm asking could serve as a generic way of getting my location data into any number of projects.

As to why not buy a running watch: I already have a smartphone.

OwnTracks seems to cover my use case, but has a lot of unnecessary features built in. I can probably use that.
