I've noticed in my last few runs that when I'm running and my pace isn't as it shows on the watch during the run, when I go to look at the app, it appears as if I'm standing still and when you look at the map you see that I was running. I've already changed the GPS, but it still didn't have any effect. Here are the runs that show up these days.

It's like I was idle on these runs but that didn't happen. I'm suspecting a GPS glitch.
