 As races were not timed to 1/100th of a second at the time, and non-winning times were not taken, no exact time is available.However, considering the terminal velocity of the horses and the distance in lengths, Phil Dandrea estimates the gap between Secretariat and Sham at 0.348 seconds.This is confirmed by the CBS footage of the race in which Sham crosses the finish line 10 frames behind Secretariat.
