According to the article, they are betting on Betfair. When the race starts, you have a delay in placing new bets (5-10 seconds) but no delay in cancelling bets.

"Natenberg: Option volatility and Pricing" I guess. Very instructive, but I have a slight preference for the Hull. They are both rather old but well explained. They give a very good starting point.
