Is it possible to upload only indoor events to strava

Strava pulls all activities from Garmin's API, and does no filtering. Personally, I keep imported activities in Stava "private" by default, and only set them visible to friends, when I want to share them. In this way, besides having the choice which type of activity will be visible, I have also the time to add some photos and comments, before publishing the workouts. 

Ah thanks for your quick answer.

I normally upload my outdoor activities like mountain biking and race biking with my Wahoo but since I have a Garmin forerunner he also upload it to strava. I know that you can erase the activity but I thought maybe you could choose which kind of activities upload automatically.

I answered it in my previous post - no, you cannot select what Strava pulls from Garmin's API, but you can disable the automatic publishing, and control it manually.

Another option is disabling the auto-upload entirely, and only upload activities you wish to publish on Strava, manually.

I could do that! 

Thanks for your help. 

Hope that they maybe change it in the future

Not without another app or service in between.

Is there an app that does it?

I asked something similar recently and someone offered one, maybe I'll find it again. 

I think it was e7andy. I do not remember the name of the app either. I bet you could google it, though

I'm using activityfix.com to modify the activities in Strava after they have been transferred.

I mute the ones I want to hide from the feed. They are still available if you look in my account, but they will not spam my followers.
