Seabiscuit [May 23, 1933 - May 17, 1947] never won any Kentucky Derby. He was named 'Horse of the Year' in 1938. But that was for his performance in races other than the Derby. It also was for his victory of November 1, 1938 over War Admiral [1934 - 1959], the Triple Crown winner of the Kentucky Derby and the Belmont and Preakness Stakes in the previous year.
Winning Colors [February 14, 1985 - February 17, 2008] was the last filly to win the Kentucky Derby. The young mare finished first in the 1988 Derby. She was the third and most recent of three fillies to claim victory in the world-famous race that's held yearly at the Churchill Downs racetrack in Louisville, Kentucky.
Yes, fillies have been among the Kentucky Derby's winners! Regret [1912 - April 11, 1934] was the first filly [female horse] to win the Kentucky Derby, in 1915, with a time of 2:05.40 minutes. Genuine Risk [February 15, 1977 - August 18, 2008] was the second filly to win the Derby, in 1980, with a time of 2:02.00 minutes. Winning Colors [February 14, 1985 - February 17, 2008] was the third and final filly to win the Derby, in 1988, with a time of 2:02.20 minutes.
Yes, the Kentucky Derby is held in Kentucky. It's held at the Churchill Downs racetrack in Louisville. The 2010 Derby represents the 136th running of the world-famous race.
Isaac Murphy was not only the first African American jockey to win the Kentucky Derby three times, he was the first jockey of any race to accomplish this feat. Murphy was inducted into the United States Racing Hall of Fame in 1955.
Two  minutes 2.66 seconds was the time that it took Mine That Bird [foaled May 10, 2006] to win the 2009 Kentucky Derby. The winning jockey was Calvin H. Borel [b. November 8, 1966]. He had been the winning jockey in the 2007 Derby. He became the winning jockey again in the 2010 Derby.
Seabiscuit did not run in the TC as a three year old.
Winning Colors won the Kentucky Derby in 1988.
Seabiscuit, who is the gratest racehorse ever!!! He returned from serios injury, to win the 1940 Santa Anita Handicap, with crippled jockey Red Pollard.
He did not. The first race in the Triple Crown is the Kentucky Derby. The Derby is restricted to three year olds. Seabiscuit was a late bloomer, when he was three he was lame and cranky due to overwork and excessive training. To compete at that level he would have had to be winning consistantly against some very tough competition.
Orb won the 2013 Kentucky Derby.
The Kentucky Derby is a horse race, you would win it on a horse, specifically a three year old Thoroughbred.
The first horse past the post will win it.
The first gray horse to win the Kentucky Derby was Determine in 1954.
There was no Kentucky Derby in 1832. Its first run was in 1875.
