Hello @jimfred
Thanks for posting about this. You are correct - that erroneous elapsed time will cause your activity to not appear correctly in Feeds.
Here are a few options to try and resolve the issue:
1. Crop your activity if the additional time is at the beginning or end of your activity: How to Crop Activities.
2. Split and crop your activity: How to Split Activities. Keep in mind, this may only fix half of your activity. The other half may continue to have data errors.
3. Manually fix any GPS time code errors:
- Use www.fitfiletools.com - online fit file tools for files, including correcting Time Adjuster and Corrupt Time Fixer. We recommend trying both if one did not resolve the issue. Additional instructions can be found here: Fixing Time Code Errors
- Download the TCX or GPX file and use a simple text edit program to "Find and Replace" the incorrect timestamp and replace it with the correct timestamp. Open the file on a desktop computer, it should open a simple text edit program. Using the same date format as the incorrect timestamp, type the correct date into the replace area to change it to the correct date. Make sure there are no additional timecode errors in the file by scrolling through the file and checking some of the dates. If so, repeat step 4. Save the file and try uploading directly to Strava: https://www.strava.com/upload/select
Unfortunately, we are unable to manually adjust or correct these activities on our end. If you continue to run into these time errors please reach out to Garmin Support directly.
Thank you Jane,
I will try your suggestions.

Hi Jane,
I tried your suggestion. I downloaded the GPX file opened in Notepad and found there were many instances where the date was 2025-05-26 as opposed to 2024-02-05. I carried out find and replace all instances of this and saved as GPX, uploaded and everything is perfect.
Thanks a million for your assistance

Hi Jane,
Thanks for this solution! I had a similar issue and used fitfiletools to correct invalid timestamp(s) - the activity now uploads and displays correctly in Strava 👍
Cheers, Peter
I have a similar problem with an activity showing on the web version of Strava on my laptop but not appearing on the app on my mobile phone. I did have a problem half way through the ride when my Garmin kept losing satallite connections and the mileage recorded is more than it should be. Is there any way this can be fixed so that it will appear in feeds on the mobile app. It's very frustrating as this is a ride I'm very proud of and would like to share. Thanks, Simon
Hi Simon, have you tried using fitfiletools per the link provided in the solution? It worked a treat for mine.
