The 1875 Kentucky Derby was the first running of that annually recurring race, taking place on May 17, 1875. [1] [2] [3] [4] It took place on May 17, 1875 on the Louisville Jockey Club Grounds as a 1.5-mile run. The track was not called Churchill Downs until 1884 and the traditional distance of 1.25 miles was not established until 1896. [5] That first Derby was a 1.5-mile race, and the traditional distance of 1.25 miles was not established until the 1896 Derby. [6] For the first several years the betting format at this race was as auction pools in which people bid for the right to bet on the horse and the highest bidder then placed his bet. The bettor who picked the winning horse won the whole pot. [7] Thirteen of the fifteen jockeys in the race, including winner Oliver Lewis, were African-American. [8] [9] Attendance was estimated at 10,000. [3]
