Check out this Flyover of my run on Strava: https://strava.app.link/xzDXS9WyCXb

Even if you had given us any context, that would be impossible. For future activities you should check your GPS reception and maybe troubleshoot issues with that. Help articles would be https://support.strava.com/hc/en-us/articles/216917247-Troubleshooting-iOS-GPS-Issues, https://support.strava.com/hc/en-us/articles/216918967-Troubleshooting-Android-GPS-Issues or consulting the manual of your recording device for a more accurate reception.

It looks like a slower run with some walk parts, the overall pace seems to correspond to the pace analysis part...

Interesting, the second post with the link to the activity was not there when I answered, else I would not have observed the missing context. The GPS doesn’t look too bad, so the question is what about the pace was wrong?

Yeah posts that include links have to be approved first I think, hence the delay
