Secretariat

     Secretariat was the greatest horse that ever ran.

The 1973 Kentucky Derby

     (I think I saw Ron Turcotte, Secretariat's jockey, use the whip in the last turn.)
     Secretariat set the track record in that race, and it still stands today.

The 1973 Preakness Stakes

     (Ron Turcotte never used the whip in this race.)
     Again, Secretariat set the track record in that race, and it still stands today.

The 1973 Belmont Stakes

     (Like the Preakness, Ron Turcotte never used the whip in this race.)
     This was Secretariat's best start in the Triple Crown races.
     Again, Secretariat set the track record in that race, and it still stands today. He beat the previous record by more than 2 seconds.
     The margin of Secretariat's victory -- 31 lengths -- is still jaw-dropping.

     Because of Secretariat, the model of the perfect horse was redrawn -- to fit Secretariat's lines.
