Google Fit Integration
Strava v.4.2.2 is able to integrate with Google Fit as long as you're running OS 4.0 and above.
Strava will send activity time, distance, and calories to Fit and will receive weight from Fit. These details will be sent to Google Fit only when the data is downloaded from the server. For type/distance/time, this happens just by scrolling through the feed. If you want to get historical Strava activity data into Google Fit, you would need to scroll back through your 'Me' feed in the app. If you want Google Fit to have the calories from a given activity, you’ll need to actually tap into the activity.
You can connect to Google Fit from either the activity save screen, the profile edit screen, or the Settings > Link Other Services Screen.
