miCoach SMART RUN User Manual page 35

Changing your zones (heart rate or pace) during Interval Workouts works the
same as changing your zones in coached workouts. (For more details about
changing zones, see section 4.2.2.1.)
The only difference is the wording.
Pausing and ending an Interval Workout works the same as in a Free Workout
(see section 4.2.1.1).
