You have 12 points. Elite at everything isn't on the menu.
Build your athlete like a character screen: six attributes, five levels each, one budget. Pour four points into a fast marathon and four into strength & power and watch the load curve drift toward overtraining while you slide from specialist to jack-of-all-trades. Go all-in on one thing and you sharpen into a specialist — at the cost of everything you didn't buy. That's not a website limitation. It's physiology.
