Imagine trying to train for pole vault, hammer throw, skateboard, surf, cross country MTB, 10m diving and dressage!
I wonder what the best strategy would be. Try and be really good in a few things or not terrible at everything.

Depends on what the scoring optimizes for. If you can get points in each discipline based on getting into the top 3 (collecting medals), you'd definitely highly specialize and skip most disciplines. If you get half the winner's points for ending last on the marathon for example, you'd have to try to participate in all disciplines you could reasonably get to the "finish line".
