So, having spent a few days playing around, I’ve found the following:
– Stava can write activities to Apple Health (and therefore to Apple Workouts)
– However, Strava can’t read activities/workouts from Apple Health
So, if you record activities on the watch using the Apple watch app (workout), you need to use a 3rd party app (RunGap) to get the data out of Health and in to Strava.
If you record activities on the watch using the Strava watch app, it will add these to Apple Health and Apple Workouts automatically.
For now, I’m using Strava on the watch and it appears to be working fine.
Cheers
Nick
