Indoor Cycle time won’t clear

On the workout type tap on the 3 dots top right corner and tap on"Open" then start a workout and when you've finished tap on "End",Scroll down to the bottom and tap on "Done" the watch will remember your last setting and next time you do a workout it should be set to open goal,if not you may have to do it again as the watch enters whatever goal you set most and uses this as a default.

In a workout, tap the circle with the 3 dots in the upper right corner to set/unset workout goals.

You may then actually have to perform a workout for the "new" goal to stick.
