This is not a question.
FYI: If this happens to you and you are a regular user of Garmin Daily Suggested Workouts, it can be really annoying.
Web research seems to indicate you have to hard reset the watch to get back your running activity DSWs.
I found a workaround. If you go to Run>Hold "up">Training>Workouts>Daily Suggestions>Settings>Running Target Type
And toggle off Pace or Heart Rate, it will get rid of "Bike Day" spam in your DSWs, and go back to Running oriented workouts.
Ya welcome
