daily double
Quick Summary
The daily double is a type of bet in horse racing where a bettor must correctly pick the winners of two specific races to win. This betting system is part of the larger pari-mutuel framework, which originated in France around 1870.12
In pari-mutuel betting, all wagers on a race are placed into a pool. After the track's commission and taxes are deducted, the remaining money is distributed among the winning tickets. The daily double is one of several combination bets that have become popular with the advent of sophisticated totalizator systems, which calculate and display betting pools and odds.2
