Garmin delayed delivering activity files to us starting around April 16, 2026 at about 00:30 UTC. Garmin is now sending the delayed activities to AI Endurance. Hopefully Garmin will resolve the issue promptly and deliver all the missing activities quickly. If you don’t want to wait you can also upload individual fit files via the fit file upload on the ‘Apps’ page.
If you have Garmin and Strava connected: When the activity finally arrives (either delayed from Garmin or via you manually uploading the fit file) if it has HRV data, it will automatically replace the Strava activity.
Is this still an ongoing issue? I thought it had been resolved but my workouts from yesterday and this morning don’t seem to have sync’d. They are syncing fine to TrainingPeaks and intervals.icu though.
the delays stopped for a while but have started again recently, will keep a close eye and continue to investigate what’s going on and keep you updated
Seems it is still ongoing today.
yes unfortunately. how long was your delay?
After 16 hours I manually uploaded the activity that hadn’t been fetched yet.
Haven’t been uploading here for at least the last 3 days. And still don’t.
Update: still experiencing massive delays. Have now changed the pipeline to log the delay on every import so over the weekend we should gather a good amount of data we can pass on to Garmin if the issue persists.
Thanks everyone for your patience
