Secretariat's Spectacular Belmont Triumph

Secretariat dominated the field by 31 lengths in the 1973 Belmont Stakes and set a race record that's yet to be beaten. The victory completed a Triple Crown that also included a race record in the Kentucky Derby. Only two horses have won the Triple Crown since — Seattle Slew and Affirmed in '77 and '78 — and with I'll Have Another retiring due to injury, it won't happen this year.
