If you have a more recent Garmin computer, there is the Live Track function, which does require a mobile phone running the Connect app. You select recipients in the app and it sends an email link at the start of a ride.
For iOS, my family also uses the Life360 app, which the teen offspring weren’t so fond of, but it lets the wife know where I am with a good level of resolution (we even used it to see where offspring traveled in Israel this summer). Paid and free versions, with the latter providing all we need.
All of these options require mobile service, of course.
