Few points I would like to share.
Most HS coaches don’t know how to handle the combined events. If you plan on doing multis at a young age you NEED to find a club team.
Coaching multis by committee doesn’t work…even though many BIG schools do it.
The best sprinters don’t make the best sprint coaches, the best throwers don’t make the best throws coaches, the best jumpers don’t make the best jumps coaches….BUT the best multis make THE BEST combined event coaches.
