How to use work out and course?

I made a course but I generally follow Garmin running suggested workouts.

I tried starting work out, then navigation then course but that just set me in course and suggested work out went into ether 

  • You have to do it in the right order. For example, for suggested workouts, I think the order is: 1) select a course 2) select training - suggested workout.

    I've tried yesterday, so I'm 100% sure it works. 

    For other types of workout, I think, but I'm not sure, that the order is reverse.
