I do remember watching it on TV, I was 16...I remember a line from the announcer near the end when Ron Turcotte turned and looked back, and it was “Sham is tiring, looks like they’ll catch him today”. I’ve never heard that line in the movie, or the clips I’ve seen since. Sham was burned up early trying to stay with Secretariat and he couldn’t go the last 3/8 at all. He would likely have showed a bit better had he not tried to stay close when the pace was other-worldly.
