I'm not sure if I got you correctly, but if you want to record an activity with your Apple Watch and use the STRAVA app on the Apple Watch, everything should be saved in your STRAVA account at the end (distance/map data, heart rate, duration...). It is not necessary to track the activity with your iPhone at the same time.
