In 1973 Secretariat ran every quarter mile in the KY Derby faster than the previous. He was moving faster at the end of the race and still holds the Derby record 1:59 2/5 seconds (mile and a quarter).
Secretariat had a heart nearly twice as big as other horses at 22lbs. He was literally a freak of nature.
Secretariat won the Belmont Stakes by a record 31 lengths over his stable mate Sham and three other rivals.
Man-O-War finished his career 20-1 with his only loss (2nd place) coming to a horse named "Upset". He did not run in the KY Derby but did win the Preakness and Belmont.
Every horses birthday is January 1.
What's the deal with the last fact? Why is this? I don't know about horses.
