Are you referring to your own home feed or other people’s feeds?  What you see and what others see will be different depending on each person’s settings.  For your own feed, have you double checked your feed preferences (click on your profile picture, settings, display preferences, and feed ordering).  If it is set to “personalized”, it will be a list of activities that Strava things you interact most with, but if you set it to “latest activities”, then it should be chronological (for the most part at least).  Keep in mind that the feed will continually change as you and others add new activities.  There isn’t a way to “pin” a special activity to the top of your feed, so anything will work its way down the feed over time.  

Thanks, but I did in fact switch my feed to “latest.” Still not appearing. It’s puzzling.

That’s odd. When I view your profile, I see it right at the top as the most recent activity.  If you are viewing on the mobile app, have you tried force-closing the app and re-opening it?  Sounds like something may not be refreshing on your end for some reason.  

The run on October 08 titled “Running coach beta?” I mean weather it’s on my PC Chrome browser or the app it’s still not showing but if others are seeing it than that’s good. I normally don’t have this visibility issue though. But yeah I don’t mean “my profile”--o  the “home feed” other activities I have appear but not this latest run.

Yep, I am seeing the Running Coach beta 10+k right at the top of your feed.  

To clarify, by feed you mean the list of activities both yours and people you follow, right? Or your profile?

If it’s the former, double check that you haven't accidentally muted the activity, here's the details:

Nope, definitely not muted and still not showing up. Only older runs from days ago are showing. Thanks though.
