Two high-profile racing executives – Tim Ritvo and Keith Chamblin – are featured on the Ron Flatter Racing Pod. In his role running the races for The Stronach Group, Ritvo discusses changes at Santa Anita, the future of the Preakness and Pimlico and even takes listener questions. And yes, he talks about post-time drag. As the National Thoroughbred Racing Association’s man in charge of the world’s biggest horseplayers tournament, Chamblin touches on the growth of contests like that, and he looks at the relationship between racing and the expansion of sports betting across the country. Saturday’s Kentucky Derby preps – the Risen Star and the El Camino Real – are previewed, and the Racehorses by the Letters feature looks at the best horse starting with the letter “O.” The Ron Flatter Racing Pod is available at Apple, Google Play, Stitcher and VSiN.com/podcasts.
