(CBS News) After I'll Have Another's victories in the Kentucky Derby and the Preakness Stakes, his entry in Saturday's Belmont Stakes presents the latest in a long line of challengers looking to end the Triple Crown's decades-long drought.
Not since Affirmed's victory by a head over Alydar in 1978 has a contender swept horse racing's three premier races. The 34-year gap stands as the longest in the history of the prize since Sir Barton won the first Triple Crown in 1919.
Dry spells aren't new to racing's prestigious prize. In 1973, Secretariat ended the 25-year reign of what was then the prize's last champion, Citation, winning the Belmont by the race's largest margin (31 lengths) and in its fastest time (2:24). (Secretariat's own reign was short-lived with Seattle Slew defeating Run Dusty Run by four lengths in 1977.)
Take a trip back to the '70s and watch the last three Triple Crown victors win what's known as the Test of the Champion.
