You decide, per athlete, whether their training calendar is coach-only or visible to their parents.
Share it
On an athlete's training calendar, turn on sharing with parents. Their parents then see a read-only version of the training plan when they sign in — the same passwordless parent access used for the schedule.
Per athlete, and reversible
Sharing is set for each athlete individually and can be turned off any time. Leave it off to keep an athlete's plan coach-only.
