Duplicate Strava Activities After P2G Uploads Peloton Workouts to Garmin

[sgtcoder]

Describe the bug
When P2G uploads Peloton workouts to Garmin, Garmin Connect later auto-syncs those same workouts to Strava. The problem is that Strava already has the workout (because Peloton sends it there directly), so Garmin’s sync creates a duplicate activity in Strava for the exact same workout.

P2G itself is not uploading to Strava, but its upload to Garmin triggers Garmin’s Strava auto-sync, which does not detect that the activity already exists in Strava.

To Reproduce

1. Peloton is linked to Strava.

2. Garmin Connect is linked to Strava.

3. Sync Peloton workouts into Garmin using P2G.

4. Wait for Garmin → Strava auto-sync.

5. Strava now shows two copies of the same workout:

   • One created by Peloton
   • One created by Garmin, after P2G uploaded it to Garmin

Expected behavior
Garmin Connect should not re-upload an activity to Strava when Strava already has the same workout from Peloton.

Additional context
This only happens because Peloton → Strava and Garmin → Strava are both active. When P2G uploads Peloton workouts into Garmin, Garmin Connect automatically pushes them to Strava, even though Strava already has the Peloton version.

I also noticed that the workout Peloton sent to Strava is 31:59, but the workout P2G sent was only 30 minutes.

Garmin and Strava had some communication issues over the past few days. Given this was previously working fine for P2G, and P2G hasn't changed. I'd be curious to see if this problem persists, or if it was just a side effect of Garmin/Strava communication troubles.

Historically this has worked fine as Strava/Garmin handled de-duping on their end.

@philosowaffle I did not realize they were having issues the past few days. I wonder if that's why my other platform is double syncing too. Do you happen to have the article or link to that so I can monitor and revisit?

I saw a handful of reddit posts, and while they don't mention double syncing issues, I'm more broadly guessing that something was broken with Garmin/Strava connection and that could impact several areas (like de-duping). Here's the Strava incident history.
