My TiVo recorded these.
The first was Chrome, but was basically just Steve Colburn being interviewed and a few shots of Chrome racing. Nothing new here.

The second was “Gonzo @ the Derby” and as about Hunter S Thompson going to the Derby to write a story. This is more about journalism than racing, and the start of gonzo journalism, but interesting.

The third was “The Shining Star of Losers Everywhere” and was really good, about a mare in Japan who saved a racetrack by losing every race. I hadn’t heard the story of Hari Urara and it was a fun story. I’d definitely recommend watching this one at least.
