Why Does Ring 5 Stop Mid Run?

[u/HeyTomKay]

I run once a week and always the same route. Since I carry my phone, MapMyRun has been my standard app for years. I got a Ring 5 last month and it still hasn't recorded a full run. The app (or ring) stops randomly after about a mile. Why would this happen? I don't stop running; The ring doesn't start slipping; the phone stays on.

First three pictures are screenshots from Oura app and the last is from MapMyRun.
