A spread bet in horse racing involves betting on the difference in finishing positions between two horses. The spread, also known as the line, is set by the bookmaker and represents the expected difference in finishing positions between the two horses.

For example, if the spread is set at 1.5, and you bet on the favorite to win the spread, they would need to finish at least 2 places ahead of the other horse for your bet to win. If they only finish 1 place ahead, you would lose the bet. Conversely, if you bet on the underdog to cover the spread, they would need to finish within 1 place of the favorite or win the race outright.

Spread bets in horse racing can be placed at the racetrack, off-track betting locations, or online with licensed horse betting sites. It’s important to always gamble responsibly and never bet more than you can afford to lose. Additionally, make sure to check your state’s regulations regarding horse racing betting to ensure that you are betting legally and safely.
