I refuse to go running with a phone - too heavy, and too distracting, running outside is one of the few places I _escape_ the phone for a bit. So I made sure to get a fitness tracker with onboard GPS. It syncs to the phone later, when I return, which then uploads workout data to the vendor's cloud.
I look at the results on my PC with a web browser, phone is a passive middleman and is never touched directly for fitness tracking.
