How to unsync my Strava from my Apple Watch

Getting some skewed data on my Watch as this scenario typically happens -

I record a run on my watch to see real-time. I record the same run on my Strava app to have more intense data and to have for historical information later as I train for a marathon.

The run recorded on my watch AND the run recorded on my Strava appear in my Activity, which then is showing that I did DOUBLE the miles, DOUBLE the calories, etc. if I look at calories burned today, miles ran/walked, etc.

How do I eliminate the Strava data from syncing to my Apple Watch/Activity?
