A brief intro to Ironman data set

I will be adding more details soon but for now this is a quick intro to my research dataset. 
@justmarkham I was thinking of a model that would predict future races times for an athlete who we have enough data for. It would be really amazing if it predicts race time for athletes with no past race history. But that would like v2.

As of now we have 247 distinct Full Iron races with 330,264 races results.
and 247 distinct half Iron races with 297,667 races results.
