# What Were The Longest Odds To Win The Kentucky Derby?

The Kentucky Derby has been held annually for nearly 150 years. Sometimes, favored horses win the race, but there have been various points throughout Kentucky Derby history where an underdog has taken the victory. The winner of the 1913 Kentucky Derby, Donerail, had the longest odds to win (pre-race odds of 91-1). At the time Donerail won, he had the fastest racing time in history, recorded at two minutes and 4.8 seconds.

## How Horse Racing Betting Works

Horse racing odds illustrate the payoff of the amount of money invested. For example, Donerail’s pre-race odds of 91-1 illustrate that for every \$1 invested into his victory, the bidder would get \$91 in return. One can determine the payoff by multiplying their original bet by the amount of profit to be gained. Although 91-1 seems like a great profit, it is also difficult to achieve.

Horse racing odds also illustrate how likely the horse is to win the race according to the mathematics behind them. If a horse has a large number of people betting on it to win, then the payoff will be smaller. Since Donerail had a 91-1 ratio, that means a small number of people were betting on the horse. So, although a bettor could get \$91 in return if Donerail won, it also meant that the majority of bettors thought it was extremely unlikely for the horse to win based on his competition.

Hayes was Donerail’s owner and trained him for his racing career. Roscoe Goose, Donerail’s jockey, recognized the potential in the horse and convinced Hayes to enter Donerail into the Kentucky Derby, despite Haye’s reluctance.
