And now for something completely different: Horse Racing Data Feeds!

http://www.tab.com.au/LiveOdds/Navigation/Racing/Default.aspx?State=2 <-- a live web service

http://horseform.racingandsports.com.au/index.asp <-- Not exactly a Data Feed, but a really nice summary of racing data.

After a very quick look, it becomes apparent that there's no such thing as a sure thing in horse racing! There's a lot of factors, such as starting barrier, jockey and even the course being run on. It's really interesting, and I feel like playing with some pretend money and see what the results are.
