Who was the greatest thourobred horse ever?
For me the greatest thoroughbred horse ever is the "Big Red"
Secretariat simply because of his greatest performances and track
records. Secretariat has a world track record that still stands
today and no ever horse can break that track record. He is also a
Triple Crown Champion and winning the last leg "The Belmont Stakes
Race by a staggering 31 Lengths.
Secretariat was by far the best racehorse but i've also heard
that he was a pretty crappy sire so that must be considered
also.
