The Stationary Activity type on Strava is designed to give you an improved visual of your data without GPS. If you are indoors and riding a stationary trainer (bike) or running on a treadmill (run) there is no useful GPS data, but there is still the need to record and analyze those efforts.
The Stationary activity page looks like any other activity detail page but without the map. Instead, the performance graph is highlighted to give you a view of your heart rate, speed, cadence or power data if available. If you have this accessory data, you will also be able to view Premium features such as heart rate zone breakdown and power analysis. If you don't have any accessory data, then there may not be a performance graph but you will still get credit for your elapsed time!
Because many stationary trainers and rollers vary in resistance, distance recorded for these activities (recorded with a speed sensor or power meter) is not considered comparable with distance outdoors, when GPS data is used. Therefore, only your moving time for a stationary activity will be added to the overall stats on your Profile page.
How to upload Stationary data
From your Garmin device, upload as you normally would on the web. The file you upload can have GPS data, but it is preferable that you turn off your GPS on your device before recording so as to get the best recorded data. If there is no GPS data detected, or if the activity is detected as stationary, Strava will automatically designate the activity under the "Stationary trainer" or "Treadmill" tags. When you go to view the activity after upload, it will appear without the map view as described in the Overview above.
Edit a Stationary Activity
To edit a stationary activity, simply navigate to the "Edit Ride" or "Edit Run" buttons on the activity detail page. Alternatively, you can edit directly from the My Activity page under the Training tab. You can add a title, bike or shoes, change the activity type, make private or add comments/ride notes. You can also make any activity stationary from this Edit page by selecting the Stationary Trainer or Treadmill checkboxes, regardless if the system automatically detected and labeled the activity as stationary.
Tips and Tricks
As mentioned above, it is best to turn of your GPS while recording a stationary activity. This will help with correct reporting of moving time and with the distance stream recorded by your data.
Didn't record with your Garmin? Enter a manual activity. You'll get the credit for the training and all you have to do is enter the basic fields like duration, time of day, date, and distance. To create a manual activity go to "Upload Activity" on your account and choose "Upload an activity manually".
Contact support if you have any questions about stationary activities, or if you are interested in having other file formats supported. When you do, please attach a file as an example to the support ticket.
