Hi @Czachomaster 

Thanks for your post and sorry to hear about the error. I'm wondering if you have a ride activity with erroneous distance data that is causing this discrepancy. Here's how to check for this:

• Sign into your account on a Web Browser at strava.com


• Go to Training>My Activities Direct link is: strava.com/athlete/training


• From the Sport option select "ride" and then select the bike from the drop down. Example:

You will then see a list of all rides assigned to that bike, and you can use the distance filter to sort it with the longest rides showing at the top like this:

I recommend scanning through that list to see where that extra distance showing for the bike is coming from. 

Let us know if that helps resolve the issue.

I found the cause of the problem. I was updating my friend's Garmin Edge Touring computer. To do this, I had to connect it to the Garmin Connect application, which I have paired with Strava. And all of my friend's activities were downloaded to my Strava. And these were mainly activities from previous years. I have a question, is there any way to remove all the activities assigned to the Garmin Edge Touring computer? Is there a way to sort them?

Hi @Czachomaster 

Glad to hear you figured it out. You can't sort them by device but you can sort by date from that My Activities screen.  You mentioned the erroneous activities are from previous years, so if you sort with the oldest activities from the top that might help you locate them, and then you can delete them from that list view.

Alternatively, if you'd like to submit a support ticket, someone from Strava Support will be able to do a bulk delete of all activities that were uploaded from a particular device. If there's a lot of them, I would recommend doing this.
