Few of us know the record times for horse races of various distances at different tracks, even though a possible track record was part of the talk leading up to the 1973 Belmont Stakes. For most of us, it took an expert announcer to explain that Secretariat had just run the fastest Belmont in history. Probably after a moment of research it was noted that the winning time was not merely the fastest 1 Â½ miles at Belmont Park, but also the fastest 1Â½ miles-time ever recorded in America.
