There was a horse running in the 3:00 at Southwell this afternoon called Caspian Dusk. It went off at odds of 1-4, making it one of the shortest priced favourites you're ever likely to see, and about as close to a certainty as you can get without actually rendering the running of the race unnecessary.
So naturally when faced with a complete certainty like that, I went the other way and backed it to lose.
It's just finished second in a field of five. I am soooo amused.
