Secretariat swung wide in the final turn to clear his path and the camera angles shows the muscles rippling through his chest as his hooves dug into that track . He chased them down even running the extra distance he still set and holds the Derby record. Sham the second horse still has the second fastest time in the Derby. Amazing performance that day . Glad it was the age of TV so it is recorded for all to see and generations to come . I don't think the Jockey ever put the whip to him in the 3 races . We are 5 years from the 50th anniversary of those victories . The tracks should make a big deal of that a true marker in time .
