Claim: Brighton Derby is located in Brighton Beach Race Course Coney Island (horse racing facility), and its distance is one mile.
Evidence: Open to three-year-olds, it was contested at a distance of one and one half miles (12 furlongs) on dirt. 
The Brighton Derby was an American Thoroughbred horse race run annually by the Brighton Beach Racing Association at its Brighton Beach Race Course at Brighton Beach on Coney Island, New York. 
The race's demise was a result of the 1908 passage of the Hart–Agnew anti-betting legislation by the New York Legislature under Republican Governor Charles Evans Hughes that led to a state-wide shutdown of racing in 1911 and 1912.
