So, random question

[Scav]

How come Standbreds can run almost 10 times more a year then thoroghbreds? Same horses basically run every weekend at Balmoral/Maywood and just curious about this? Because of the bred, not having to carry weight but 'pull' it? I know someone knows this answers, so don't be shy and not answer it because it is about standbred's. I am SLOWLY starting to get down with Meadowlands and Maywood/Balmoral
