Our HS coaches start in September 2-3 days per week working with the girls and go all through winter. Our season starts in March and ends late June. Head Coach probably puts over 1,000 hours a year into the sport.
Here coaches are not allowed to gather their team during the school year/out of season. We can do open gyms, stuff like that, but no actual, official team events.
Even with the limitations I have, with all the different teams, individual lessons, open gyms, and the other things I mentioned (and some I haven't), it's easily 1,000 hours a year.
