Here are the track and field stats I would be interested in knowing:
Odds of winning a mid-distance race if leading 25% , 50%, 75% into the race
Odds of winning if somewhere in the middle of 25%, 50%, 75% into the race
this type of analytics is really about splits and strategy and could be transferred to cross country and long distance running.
Moneyball is about strategy and tendencies, why a walk is valuable, hitting to certain parts of the field. So similarly i'd like to know do winners of races always go out hard, sit and kick, etc. Comparing results is done via results websites, i'm more interested in the splits data, which you only really get at NCAA's and a few big invitationals.
If someone wants to do that math, I would be interested.
