That’s possible and I k ow the watch will do this. I run with both my phone and Apple Watch. For long runs 20-26 miles, I use the phone for music to my AirPods. I run slow enough for the watch battery to be drained after a marathon of I try to have my watch do it all.
I’ve had a few instances where the running track gets all wonky when I go through something like a long underpass tunnel. It’s long enough to miss a GPS signal for many minutes. Instead, it guesses where I am based on distance to cell towers (I think). Or at least, that’s what the running trace seemed like to me. Everytime I went under a tunnel, I found out later that I ran a 3 minute mile — on miles 16, 20, and 22 (that’s not possible).
Now I just disable Bluetooth on my watch entirely while doing long runs. I’ve found the watch by itself to be more accurate, in general.
