Question

Who is the biggest underdog to win the Kentucky Derby? What were it's odds?

Answer 1

ignore barbaro she is a flaming idiot.  7-2 is a favorite not a long shot

Answer 2

The horse that won at the highest odds was Donerail, who paid $184.90 to win on a $2 bet in 1913.  This was at the dawn of pari-mutuel wagering and the payoff perhaps reflects more uncertainty about the system of wagering than the actual status of Donerail.

Most people feel that the true biggest upset was actually in 1940, when Gallahadion won and paid $72.40 to win.  He upset Colonel E. R. Bradley's Bimelech, who was considered invincible and was a short-priced favorite to win.  Gallahadion's victory was a shocker, much as if a horse that was 35-1 had upset Secretariat.

Dark Star, who paid $51.80 to win, was another shocker-- the more so now in retrospect, because the horse that finished behind him, the immortal Native Dancer, had never lost a race before, and never lost a race after the Derby.  Talk about picking the wrong race to lose!  Jockey Eric Guerin is generally discredited with the Dancer's loss, one sportswriter disgustedly saying of Guerin's ride, "He took that colt everywhere [on the track] except the lady's room!"

All of which just goes to show:  no matter how hot a favorite is, how much he is bet down at the mutuel windows, anything can happen.  Horses don't read the tote board.
