Just to add to this, I would center it around the 'process' of trying to select the winners if this is all being done off historical data, otherwise people will just game the system via google/wikipedia. That being said, I definitely like the idea of having it be a social sort of tool where people compete on the winners. Perhaps using the data you can somehow figure out how to generate random horse races based on real historical data and real horses and then people can really try to pick the winners instead of game the system for points through a simple google search.
