About Thoroughbred (Flat) Betting
Flat thoroughbred racing — run on the level with no jumps — is the most heavily bet form of horse racing globally, from the US Triple Crown and the Breeders’ Cup to the major European and Australian carnivals. It is the core of every racebook and of the racing offering at full-service sportsbooks.
Betting blends fixed-odds and, in many markets, pari-mutuel (tote) pools, with deep exotic markets on a single race or across multiple legs.
