Potential duplication of workouts with HealthFit

I understand that I can use the Apple Watch Indoor Cycling workout to track my indoor training session and then via the HealthFit app transfer it to my Strava account, which is great, But will this potentially end up with duplicate sessions in the health and activity apps. Please note for outdoor rides I link my Garmin Edge 520 to my Strava account, which links back to my activity app on my watch and iPhone. I am trying to keep the mileage for the indoor stationary trainer, which is not recorded in the Watch Cycling app, so I put them it manually into Strava, but this results in a duplication in the activity app. I can use the Strava watch app and pick indoor cycling, but then I do not get any heart rate info and calorie info that the Watch app provides.
