The Belmont Stakes is the final race in the annual Triple Crown of thoroughbred horse racing. The race is 1.5 miles in length, and the record for the fastest time of 2 minutes, 24 seconds is held by Secretariat, the 1973 winner. We compared Secretariat’s time from 1973 with the time of each winner of the Belmont Stakes for the years 1999–2011. The following data represent the differences (in seconds) between each winner’s time for the years 1999–2011 and Secretariat’s time in 1973. For example, the 1999 winner took 3.80 seconds longer than Secretariat to finish the race.
