actually..Secretariats Belmont time of 2:24 flat is not only the stakes and track record, its also the world record that still stands. He shaved 2 full seconds off the the record that day...also, his Kentucky Derby time for a mile and a quarter was 1:59 and 2/5ths....the only sub 2 minute Derby ever. His time at a mile and a quarter in the Belmont was an astonishing 1:59 flat. In the 12 furlong Belmont..he ran the first 6 furlongs in 1:09 4/5, considered a world class time for 6 furlongs...and still won going away. Its still to me, the greatest single sports performance ever..
DIRT record.
The absolute record had already been set by Kelso and Fiddle Isle, respectively. Fiddle Isle had the WR at 2:23.
Monarchos also beat the sub-2:00 Derby in 2001.
