Q: Passage: The Belmont Stakes is traditionally called "The Test of the Champion" because of its 1.5 mile length -- by far the longest of the three Triple Crown races, and one of the longest for a first-class race in the United States on the dirt. It is also known as "The Run for the Carnations" because the winning horse is draped with a blanket of white carnations after the race, in similar fashion to the blanket of roses and black-eyed Susans for the Derby and Preakness, respectively. The winning owner is ceremonially presented with the silver winner's trophy, designed by Paulding Farnham for Tiffany and Co. It was first presented to August Belmont, Jr. in 1896 and donated by the Belmont family for annual presentation in 1926.
